Heart disease is one of the most common causes of death in the United States — one in five deaths, according to the CDC. But there's not a long-term solutions for patients — even for those lucky enough to have a successful heart transplant. But a Houston-headquartered medical device company is working on one.

BiVACOR has created a technology that, theoretically, could completely replace a patient's heart and last them the rest of their lives.

"The design is critical," says Thomas Vassiliades, CEO of BiVACOR, on the Houston Innovators Podcast. He joined the organization last year after spending 20 years of a heart surgeon, then transitioning to medical device development over a decade ago.

Vassiliades explains the industry's challenges on the show, saying that there's no comprehensive, lasting replacement to the human heart on the market. While some treatments — like transplants and medical devices that partially replace the heart's capabilities — exist, nothing that completely replaces the heart lasts longer than 10 to 12 years.

"The BiVACOR system is based on magnetic levitation," Vassiliades says about the technology. "Our pump is just one moving impeller that sits in the middle of the housing where the blood is. Imagine an artificial heart — the container that has your blood — and the device spinning in the inside — basically a wheel spinning your blood to the rest of your body.

"The device is suspended by magnets — it's not touching anything," he continues. "So, theoretically, the device has no wear and can last as long as the patient can possibly live. That's new to the field."

Daniel Timms, BiVACOR's founder and CTO, knew there had to be a better, more permanent solution and has been working on the technology since he was a postdoctoral student at Queensland University of Technology in Australia. His work took him to Houston's Texas Heart Institute, the "center of the universe when it comes to blood pumps," says Vassiliades.

The company recently raised $18 million in funding to support its growing team and continued growth. BiVACOR is a Class 3 medical device — the most rigorously regulated type of device, so the funding raised will support the company as it continues to meet the FDA's requirements and proceeds into implantation and clinical trials.

While headquartered in Houston and has close ties to THI, most of BiVACOR's team works out of Huntington Beach, California, just 30 minutes away from its manufacturing partner — something that has been critical for the design phase. Other employees work in Europe and Australia, which has resulted in government grant funding. Each market the company works in has a strategic purpose — and Houston's role is testing.

"We're going to be training all our clinical sites in Houston, and we're going to continue to do ongoing testing," he says. "We're very comfortable with the design of the device, ... but there's always more. And we have a long-term plan to iterate on the device to make it even better."

Vassiliades shares more of the challenges he's facing as he commercializes BiVACOR's technology on the podcast. Listen to the interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

mover and shaker

A Houston-based preclinical artificial heart device company has a new head honcho as it grows its team and further develops its technology.

BiVACOR named Thomas Vassiliades as CEO effective immediately. He replaces the company's founder, Daniel Timms, in the position. BiVACOR is on track to head toward human clinical trials and commercialization, and Vassiliades is tasked with leading the way.

“BiVACOR led an extensive CEO search, and Tom was the clear choice given his experience, background, leadership style, and exceptional track record,” says Timms in a news release. “Tom has the skillset and credibility to guide BiVACOR through its next chapter of transformation and advancement as we undertake the next stage of clinical activities leading up to First in Human early feasibility studies.”

Vassiliades has over 30 years of experience within the medical device industry as well as cardiothoracic surgery. He was most recently the general manager of the surgery and heart failure business at Abiomed and held several leadership roles at Medtronic. Dr. Vassiliades received his MD from the University of North Carolina, and his MBA was achieved with distinction at Emory University.

“I am excited and honored to join the BiVACOR team, working closely with Daniel and the entire team as we look forward to bringing this life-changing technology to the market,” says Dr. Vassiliades in the release. “Throughout my career, I’ve been guided by the goal of bringing innovative cardiovascular therapies to the market to improve patient care and outcomes – providing solutions for those that don’t have one. BiVACOR is uniquely well-positioned to provide long-term therapy for patients with severe biventricular heart failure.”

Timms will take over BiVACOR's technical team working on the Total Artificial Heart system as CTO. The device, billed as the first long-term therapy for patients with severe heart failure, is an implantable artificial heart based on rotary blood-pump technology. Similar in size to an adult fist, it is small enough to be implanted in many women and some children yet capable of delivering enough cardiac power to a man who's exercising. Unlike the two-chamber human heart, BiVACOR's device features a single chamber.

The medical device company, which has operations in Houston and Australia, recently announced the addition of eight new employees doubling their team. The growth comes following its series B raise last year.

“It is a testament to the great progress the team has made and to the importance of the unmet clinical need addressed by the Total artificial Heart technology," Timms says on the appointment of Vassiliades. "We look forward to Tom’s leadership as BiVACOR navigates the path to commercialization.”

Houston named a top market for remote tech workers, startup doubles its staff, and more innovation news

short stories

Houston is starting 2022 strong in terms of innovation news, and there might be some headlines you may have missed.

In this roundup of short stories within Houston startups and tech, the Bayou City is ranked based on its ability to employ remote tech talent, a coworking company opens a new location, a med device startup doubles its staff, and more.

New report finds Houston a top market for remote tech talent

In a new report, Karat — a Seattle-based human resources company — looked at which metros were best for attracting remote tech talent. The company first completed the report based on 2020 due to a changing workforce spurred by the pandemic.

"Last year we took our first look at the rapidly expanding remote software engineer hiring landscape. As more organizations shifted to remote or hybrid working models we had started to see significantly improving candidate performance outside of the more-established tech hubs," writes Patrick Wu, data analyst at Karat, in a blog post. "Today, as even more top tech companies commit to hiring remote software engineers, we’re taking a look at how this landscape has continued to evolve."

Houston ranked No. 6 this year in the list of 10 metros just ahead of No. 7 Austin. Last year, Houston ranked as No. 2 and Dallas at No. 9, but that North Texas metro fell off the top 10 for 2021. Pittsburgh maintained its top spot on this list year over year.

BiVACOR, a Houston-based cardiatric medical device company, announced that it has doubled the size of its team with the addition of eight team members. The growth comes following its series B raise last year.

“The diversity of skills and experience throughout the company is something we are very proud of, and I am pleased to welcome this all-star group of individuals to the team,” says Daniel Timms, BiVACOR founder and CEO, in a December news release. “They will each play an integral role in the overall accomplishments of BiVACOR, specifically as we undertake benchtop and preclinical verification activities so that we can commence our First in Human early feasibility study in the near future.”

Here's who recently joined the company at both its United States and Australia-based operations:

  • Nathan Kong, purchasing administrator
  • Farhad Akhavan, systems engineer
  • David Duarte, verification and validation engineer
  • Paul Chiver, manufacturing technician
  • Lindsey Brede, financial controller
  • Dawnel Scott, director QA/RA
  • Mairi Maclean, director of product development
  • Nicole Bartnikowski, scientific manager (Australia)

“Having the ability to attract and hire individuals with the industry knowledge and pedigrees of this world-class team is a testament to how BiVACOR is perceived in the industry," Timms continues. "Each of them brings a unique perspective and skillset to BiVACOR and will play an important role in furthering our technology.”

BiVACOR is developing its Total Artificial Heart, or TAH. The device, billed as the first long-term therapy for patients with severe heart failure, is an implantable artificial heart based on rotary blood-pump technology. Similar in size to an adult fist, it is small enough to be implanted in many women and some children yet capable of delivering enough cardiac power to a man who's exercising. Unlike the two-chamber human heart, BiVACOR's device features a single chamber.

Houston-based artificial heart company snags $22M in fresh funds

money moves

Houston-based medtech company BiVACOR has picked up $22 million in funding — in the form of a series B round and a federal grant — to propel development of its Total Artificial Heart device for treatment of severe heart failure.

In a May 19 news release, BiVACOR says it received a series B round of $19 million and a National Institutes of Health grant of $3 million. Boston-based Cormorant Asset Management and Australia's OneVentures, through its OneVentures Healthcare Fund III, led the round.

OneVentures first invested in BiVACOR three years ago. According to Australia's Financial Review, OneVentures initially pumped $3 million (Australian dollars) into BiVACOR, with the potential of contributing as much as $10 million if BiVACOR met certain milestones. BiVACOR received a round of seed funding from U.S. investors in 2013.

"BiVACOR's one-of-a-kind technology is supported by a remarkable team that has moved this technology a significant distance toward the clinic," Paul Kelly, managing partner of OneVentures, says in BiVACOR's news release.

The fresh cash will support preparation for the first human trials of the device. As a short-term measure, the device can be implanted in someone awaiting a heart transplant. It's also designed to be a long-term alternative to a heart transplant.

The BiVACOR device, billed as the first long-term therapy for patients with severe heart failure, is an implantable artificial heart based on rotary blood-pump technology. Similar in size to an adult fist, it is small enough to be implanted in many women and some children yet capable of delivering enough cardiac power to a man who's exercising. Unlike the two-chamber human heart, BiVACOR's device features a single chamber.

"The commitment and interest from our investors validate our technology and the need for improved options to treat end-stage biventricular heart failure," says Daniel Timms, founder and CEO of BiVACOR. "With this financing, we will be able to expand our world-class team and undertake … verification activities so that we can commence our first-in-human early feasibility study in the near future."

Founded in 2008, BiVACOR maintains offices in Cerritos, California, and Brisbane, Australia. The company is affiliated with Houston's Texas Heart Institute, where the world's first artificial heart was implanted. BiVACOR's headquarters is at the Texas Medical Center complex.

The company employs about a dozen people and says the funding will enable it to bring on another 10 employees.

For 13 years, BiVACOR has been working on technology aimed at eliminating the need for heart transplants. Thus far, the BiVACOR device has been tested only on cows.

"In heart failure, the heart becomes unable to pump enough blood to keep the body healthy and strong. At least 26 million people around the world are living with the disease, and the number is rising as populations age," IEEE Spectrum reported in 2019. "Patients with severe heart failure have a bleak outlook: Their best option is a heart transplant, but the limited number of donor hearts means that only about 5,000 patients around the world receive transplants each year. Thousands more patients are eligible for transplants, and some die while waiting for a donor organ."

Houston founders launch edtech startup, pilot to pinpoint why students are struggling

learning gaps

Early detection. It sounds simple enough: identify a problem before it has the chance to become a bigger one.

But in practice, early detection is much more difficult to navigate, especially in education, when it comes to identifying the reasons behind a student's academic struggles.

That’s why co-founders Alapati “Al” Ware and Estela Montanez launched Progress Report, a Houston-built K-12 learning-intelligence platform designed to go beyond identifying that a student is struggling.

The platform recently began its pilot program with 35 educators and more than 200 students in Texas and Arizona.

“It’s a micro-learning school that works with children with disabilities, primarily dyslexia and nonverbal students,” Ware tells InnovationMap.

The platform is also being used by homeschool parents, home teachers and Houston educators, including those at SWPS College & Career Preparatory Academy, a Houston charter school.

Ware says Progress Report was designed to fill a gap he and Montanez saw in existing edtech. Some platforms cater almost entirely to students, leaving teachers with little insight into if and how a child is learning. Others focus heavily on district data, where “the student is just a number,” leaving teachers to navigate disconnected tools.

“Our goal was [to] focus purely on the teacher because the teacher is the backbone,” Ware says.

Progress Report traces student performance to learning gaps and prerequisite skills, helping educators understand not only where a student is struggling, but what may be causing it.

The platform then helps teachers build individualized instruction for general education students, students with special education and Individualized Education Program (IEP) needs, and Spanish-speaking learners—all within one educator-controlled system.

The goal is to reduce the guesswork and hours of manual work educators can spend developing individualized lesson plans.

For Ware and Montanez, the mission is also personal.

The concept dates back to around 2023, when the co-founders first had to navigate and address their children’s educational needs.

Ware, Progress Report’s CEO and CTO with a background in edtech, built the platform end-to-end after watching his daughter, who had an IEP related to speech, struggle to get the support she needed.

Montanez, the company’s COO, brought another perspective. Her son is on the autism spectrum. She now leads Progress Report’s operations, partnerships and pilot execution while helping carry its focus on bilingual families from Puerto Rico to Houston.

Together, they began researching ways to personalize their children’s learning and help them progress academically. Montanez’s son went on to become an AP student and high school athlete, while Ware’s daughter began reading more than two grade levels above her grade, they tell InnovationMap.

But Progress Report isn’t designed simply to give a struggling student more work.

Take a student who appears to have difficulty with math.

The problem may not actually be math, the founders share. The student could understand the calculations but struggle to comprehend complex words used in a math problem.

Progress Report is designed to trace those performance patterns back to learning gaps, prerequisite skills or other instructional barriers. From there, it can recommend a next instructional step while leaving the educator in control.

The same concept applies to accommodations.

The system can read IEPs, 504 Plans, Present Levels of Academic Achievement and Functional Performance (PLAAFPs), evaluations and other special education records. Approved IEP goals can then be mapped into the student’s learning graph, while accommodations can carry over into lesson planning and question delivery.

The founders say that approach separates Progress Report from simply adding another artificial intelligence chatbot to a classroom. And still, they believe teachers have to remain at the center.

Teachers, in fact, helped build Progress Report.

The founders began meeting with Houston-area educators months before the pilot. Their feedback helped shape the platform before testing began.

“We’ve been building alongside these educators,” Ware says.

Parents are another piece.

Progress Report can give parents access to their child’s learning record so they can see learning gaps as they develop. Teachers can also see information on work being completed at home when the parent and educator are working together.

After the pilot wraps, Ware and Montanez plan to introduce a $29.99 monthly subscription for homeschool parents, teachers and other educators. They say the price was intentionally kept relatively low to help make the tools more accessible.

They are also exploring ways to work with organizations that could help families who can’t afford the platform.

Moving forward, the goal is considerably bigger.

Over the next five years, Ware and Montanez want Progress Report to become what they describe as a “gold standard” in every state. They know getting there will require building relationships with educators, technology leaders, policymakers and school board members.

For now, they’re starting with a few hundred students and a question that sounds simple but can be remarkably difficult to answer: Why is this student struggling?

If Progress Report works the way its founders envision, teachers and parents will have a clearer answer.

Pioneering cohousing development opens in Houston's historic 2nd Ward

Housing in Hou

An experimental, multi-generational building in the East End is now open and accepting residents. Only 10 of the 33 units remain available at East End Commons, the first project from CoHousing Houston.

Located at 115 Lenox, East End Commons was first conceived in 2017 and is designed to combine the security of home ownership with the community aspect of apartment life, essentially a condominium but with added focus on bringing neighbors together.

Units range from 900-2,000 square feet, offering ample private home space, but with a large Common House area and central courtyard for gatherings, working, and interaction. Large front porches encourage people to spend time outside where they can meet their neighbors, as do extensive foot paths for casual meetings.

"At East End Commons, you know your neighbors before you move in — so you have a network of people and spaces that are immediately there for you," said founding resident Kelli Soika. "We designed for larger shared spaces versus larger personal spaces in order to foster the breakdown of the barriers that lead to loneliness."

Combating loneliness and isolation is certainly necessary. A 2025 survey conducted by the American Psychological Association shows that most Americans feel a sense of societal division and lonely. A loss of "third spaces," where people gather outside the home or work, is a prime factor. East End Commons aims to alleviate some of that disconnectedness.

"I wanted to live in a neighborhood that is imbued with a sense of community above the individual, like we have all experienced in Houston during times of disaster recovery," said Lynn Morstead, one of East End Commons‘ founding residents. "In those instances, such as Hurricane Harvey, we surface from our separateness and come together in new and unexpected ways. With East End Commons, the goal is to translate that notion beyond a set period of time and make it a fixture of everyday life. I call it 'disaster-free neighborliness.'"

East End Commons was designed by Kathleen English of English + Associates. Sustainability is part of the project's design, with amenities such as geothermal heating and cooling exchange HVAC, pre-heated water systems, low-energy use air conditioning and heating, and native landscaping.

Prices for units range from $300,000 to the $900,000s, which can be more than double the home price in the rapidly gentrifying East End. HOA fees not only help maintain communal areas, they also cover shared internet, water, and other communal expenses. Similarly, government of the building is handled democratically via a community board that aims to make decisions by building consensus.

MD Anderson president to retire after nine years, interim successor named

retirement plan

An era is ending at The University of Texas MD Anderson Cancer Center.

On Aug. 26, Dr. Peter WT Pisters announced his plans to retire from his role as president of the comprehensive cancer center. He will work on a smooth transition of leadership with interim president Dr. Jeffrey E. Lee throughout September.

“I first arrived at UT MD Anderson 32 years ago with a passion for doing everything I could to advance our mission to end cancer. Serving as the only faculty member to become president, and now marking nine years in the role, I can say with great pride and gratitude that there is no better place than UT MD Anderson to turn hope into healing for patients and families everywhere,” Pisters said in a news release. “With a timeless strategy, a strong leadership team, unprecedented levels of financial health, and a priceless culture anchored in our deeply held Core Values, now is the right time for me to transition to other opportunities. UT MD Anderson has never been stronger, and its future has never been brighter.”

Pisters assumed the presidency in 2017 and helped launch some of the most cutting-edge new clinics in MD Anderson history. One of those was the James P. Allison Institute, named for the Nobel Laureate scientist who discovered a way to suppress immune response on tumors so that immune cells would attack cancer cells instead. As head of his titular clinic, Allison pioneered several new immunotherapies against cancer.

Pisters also oversaw the creation of the Institute for Data Science in Oncology in 2024, an innovative consortium of scientists dedicated to enhancing single-cell imaging to improve precision in cancer treatments. The institute also brought together teams to use data-driven analytics regarding safety, quality and access.

The UT System Board of Regents praised the leadership and work of Pisters in a statement, wishing him well in the next phase of his career.

“The Board of Regents and I are profoundly grateful to Dr. Pisters for his exceptional presidency over the past nine years and for thoughtfully concluding his service when UT MD Anderson is thriving at its best position of peak performance, strength and impact. We wish him our very best with his retirement and in his next chapter,” Kevin P. Eltife, chairman of the UT System Board of Regents, added in the release.
