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."

Pharma giant considers Houston for $1B manufacturing campus

in the works

Another pharmaceutical giant is considering Houston’s Generation Park for a manufacturing hub.

According to a recent filing with the Texas Jobs, Energy, Technology and Innovation (JETI) program, Bristol Myers Squibb Co. is considering the northeast Houston management district for a new $1 billion multi-modal pharmaceutical manufacturing campus.

If approved, the campus, known as Project Argonaut, could create 489 jobs in Texas by 2031. Jobs would include operations technicians, engineering roles, administrative and management roles, production specialists, maintenance support, and quality control/assurance. The company predicts annual average wages for these positions to be around $96,000, according to the filing.

The project currently includes the 600,000-square-foot facility, but according to the filing, Bristol Myers Squibb “envisions this site growing in scale and capability well beyond its opening configuration."

The Texas JETI program offers companies temporary school property tax limitations in exchange for major capital investment and job creation. E.R. Squibb & Sons LLC applied for a 10-year tax abatement agreement in the Sheldon Independent School District.

The agreement promises a $ 1 billion investment. Construction would begin in 2027 and wrap in 2029.

“The proposed project reflects [Bristol Myers Squibb Co.’s] enduring commitment to bringing innovative medicines to patients and ensuring the long-term supply reliability they depend on,” the filing says. “The proposed project is purpose-built to support and manufacture medicines spanning multiple therapeutic areas and modalities, positioning the site as a long-term launch and commercial campus for decades to come. These medicines will provide therapies to the [Bristol Myers Squibb Co.’s] patients located in markets both nationally and internationally.”

The Fortune 100 company is considering 16 other cities for the new manufacturing facility in the Central and Eastern markets in the U.S. According to the Houston Chronicle, Bristol Myers Squibb Co is still in the “evaluation process” for its potential manufacturing site.

Last fall, Eli Lilly and Co. selected Generation Park for its $6.5 billion manufacturing plant. More than 300 locations in the U.S. competed for the factory. Read more here.

Houston health tech co. lands NIH grant for AI cancer prediction tool

fresh funding

Houston-based CellChorus and Stanford Medicine were recently awarded a Phase I Small Business Innovation Research grant for the company's AI platform to test how certain cancer patients will respond to therapies.

The funding comes from the National Cancer Institute of the National Institutes of Health. According to a filing, the grant totaled just under $400,000.

CellChorus, which spun out from the University of Houston’s Technology Bridge, has developed TIMING (Time-lapse Imaging Microscopy In Nanowell Grids), which analyzes the behavior of thousands of individual immune cells over time and can identify early indicators of treatment success or failure.

The company will work with Stanford's Dr. David Miklos and Dr. Saurabh Dahiya, who have built the Bone Marrow Transplantation and Cell Therapy Biobank. The biobank manages and stores biological samples from patients treated at their clinic and in clinical trials.

"Predicting which patients will achieve durable responses after CAR-T therapy remains one of the most important challenges in the field,” Miklos said in a news release. “We aim to uncover functional cellular signatures that can guide treatment decisions and improve patient outcomes.”

The project will specifically profile cells from patients with relapsed/refractory large B-cell lymphoma (r/rLBCL). According to CellChorus, only about half of r/rLBCL patients who receive CAR-T therapy "achieve a durable, long-term remission." Others do not respond to therapy or experience relapse.

“The sooner we know whether a cancer therapy is working, the better. To maximize patient benefit, we need technology that can provide a robust and early prediction of response to therapy. The technology needs to be scalable, cost-efficient, and capable of rapid turnaround times,” Rebecca Berdeaux, chief scientific officer of CellChorus, added in the release. “We are excited to work with Drs. David Miklos and Saurabh Dahiya and their colleagues on this very important project.”

CellChorus has previously received SBIR grants from federal agencies, including a $2.5 million award in 2024 from its National Center for Advancing Translational Sciences (NCATS) and a $2.3 million SBIR Fast-Track award from the National Institute of General Medical Sciences in 2023.

Houston museum showcases America's founding documents in rare exhibit

Experience History

As the United States prepares to celebrate its 250th birthday, Houstonians have a chance to see rare documents from the founding of the nation. Freedom Plane National Tour: Documents That Forged a Nation, presented by the National Archives Foundation, will be on display at the Houston Museum of Natural Science through Monday, May 25.

The collection includes a rare engraving of the original Declaration of Independence; official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton; a draft of the Bill of Rights; the Treaty of Paris, the documented that recognized America's independence from Great Britain; and the tally of votes approving the Constitution.

The National Archives specifically chose Houston as one of only eight cities in the country to host the exhibit as a means to help the documents reach a wider audience outside of the main hub of semiquincentennial events in New England and the Washington, D.C. area.

"One of the things we decided when we put the tour together because we wanted to be off the East Coast," said Patrick Madden, CEO of the National Archives Foundation, who was onsite for the exhibit's opening in Houston. "There's a lot of 250th celebration stuff happening in the original 13 colonies. How do we get it to major markets where larger numbers of people can see it? So in the case of Houston, obviously, [is a] major market in this part of the country, but also we've partnered with the museum twice before with National Archives exhibits, so we knew that they would be up to the task of handling the exhibit and the crowds."

The star of the collection is a rare engraving of the original Declaration of Independence. Secretary of State and future president John Quincy Adams commissioned 200 exact replicas of the document from engraver William J. Stone in 1823. Less than 50 now remain. Madden joyfully pointed out that there are errors in this document, a potent reminder that the men who forged a nation made mistakes.

"There's a couple of typos in it where they had to make corrections," said Madden. "So even the founders, you know, they're all human. That resonates because here these people are making this move against the most powerful nation in the world and putting their lives on the line for a country based on ideas."

Other impressive parts of the collection include official Oaths of Allegiance signed by George Washington, Aaron Burr, and Alexander Hamilton, as well as one of the drafts of the Bill of Rights. Many states would not ratify the Constitution until certain rights were included in the document, leading to Washington going on a national tour assuring state leaders enshrining protections was first on the list. The draft copy on display specifically shows the First Amendment in progress.

Houston is the fourth stop on the exhibition's tour, which will take the documents to Denver, Miami, Dearborn, and Seattle through the summer. Freedom Plane is just one part of a larger patriotic celebration at the HMNS, which includes a film series celebrating American science and culture and general Americana decoration throughout the main hall.

Admission to Freedom Plane is free to the public, but separate from general admission to the museum. Space is limited, and passes are available on a first-come, first-serve basis. Non-members should expect long waits or the possibility that the day's passes are sold out. Only museum members can reserve passes for specific times. Flash photography is prohibited due to the fragile nature of the documents.
