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."

Activate

Hard tech incubator Activate supports scientists in "the outset of their entrepreneurial journey." The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. It named its second Houston cohort this summer.

This year, the incubator grew to include its largest number of concurrent supported fellows, with 88 companies currently being supported nationally. In total, Activate has supported 296 fellows who have created 236 companies. Those companies have raised over $4 billion in follow-on funding, according to Activate. In Houston, it has supported several Innovation Awards finalists, including Solidec, Bairitone Health and Deep Anchor Solutions. It is led locally by Houston Managing Director Jeremy Pitts.

EnergyTech Nexus

Cleantech startup hub EnergyTech Nexus' mission is to accelerate the energy transition by connecting founders, investors and industrial stakeholders and helping to develop transformative companies, known as "thunderlizards."

The hub was founded in 2023 by CEO Jason Ethier, Juliana Garaizar and Nada Ahmed. It has supported startups including Capwell Services, Resollant, Syzygy Plasmonics, Hertha Metals, EarthEn Energy and Solidec—many of which are current or past Innovation Awards finalists. This year Energy Tech Nexus launched its COPILOT Accelerator, powered by Wells Fargo Innovation Incubator (IN²) at the National Renewable Energy Laboratory (NREL). COPILOT partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. Energy Tech Nexus also launched its Liftoff fundraising program, its Investor Program, and a "strategic ecosystem partnership" with Greentown Labs.

Greentown Labs

Climatetech incubator Greentown Labs offers its community resources and a network to climate and energy innovation startups looking to grow.

Rice University launches  engineering-led brain science and health institute

brain research

Rice University has announced the creation of a new interdisciplinary center known as the Rice Brain Institute (RBI).

The new hub will aim to use engineering, natural sciences and social sciences to research the brain and reduce the burden of neurodegenerative, neurodevelopmental and mental health disorders.

“The Rice Brain Institute reflects Rice’s strength in collaboration without boundaries,” Rachel Kimbro, dean of the School of Social Sciences, said in a news release. “Our researchers are not only advancing fundamental science but they’re also ensuring that knowledge reaches society in ways that promote human flourishing.”

RBI researchers will work in thematic clusters focusing on neurodegeneration, mental health, brain injury and neurodevelopment. The clusters will work toward goals such as significantly improving key brain health outcomes, reducing mortality and mental health disorders and improving quality of life for patients living with brain injuries and neurodevelopmental disorders, according to Rice.

The institute will focus on “engineering-driven innovation,” rather than traditional neuroscience, to design tools that can measure, model and modulate brain activity based around Rice’s expertise in soft robotics, neuroimaging, data science and artificial intelligence—making it unique among peer organizations, according to Rice.

Additionally, RBI will be structured around three collaborative Rice “pillars”:

  • The Neuroengineering Initiative, launched in 2018, brings together neuroscience, engineering, and related fields experts
  • The Neuroscience Initiative, a new initiative that brings together cell biologists, neurobiologists, biochemists, chemists and physicists to explore fundamental mechanisms of the brain and nervous system
  • The Brain and Society Initiative, also a new initiative, considers brain research within the broader social and policy landscape

Rice’s Neuroengineering Initiative has already garnered more than $78 million in research funding, according to Rice, and has established major partnerships, like the Rice-Houston Methodist Center for Neural Systems Restoration.

“Rice is uniquely equipped to bridge and connect scientific understanding of the brain and behavior sciences with the technologies and policies that shape our world,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, added in the news release. “By uniting faculty in neuroengineering, neuroscience and psychological sciences, this interdisciplinary hub embodies the kind of bold, nimble collaboration that allows Rice to turn discovery into societal impact to save lives and enhance human flourishing.”

The formation of the RBI coincides with recent support of the Dementia Prevention Research Institute of Texas (DPRIT), which landed voter approval earlier this week and aims to make Texas the center for dementia research via brain-health tech. According to the World Economic Forum, brain disorders and mental health disorders cost the global economy an estimated $5 trillion per year and could be as high as $16 trillion by 2030.

“Few areas of research have as direct and profound an impact on human well-being as brain health,” Rice President Reginald DesRoches added in the news release. “As rates of Alzheimer’s, dementia and other neurological diseases rise in our country and around the world, universities have a responsibility to lead the discovery of solutions that preserve memory, movement and quality of life. We all know someone who has been affected by a brain-related health issue, so this research is personal to all of us.”

Texas voters OK $3 billion for new dementia research institute

state funding

Texas voters on Nov. 4 overwhelmingly approved a ballot measure that provides $3 billion in state funding over a 10-year span for the newly established Dementia Prevention and Research Institute of Texas (DPRIT).

Thanks to the passage of Proposition 14, Texas now boasts the country’s largest state-funded initiative dedicated to dementia research and prevention, according to the Alzheimer’s Association. Up to $300 million in grants will be awarded during the 10-year funding period.

“This is a transformative moment for Texas and for the fight against Alzheimer’s and all other dementia,” said Joanne Pike, president and CEO of the Alzheimer’s Association. “Texans have chosen to invest in hope, innovation, and solutions for the millions of families affected by these devastating diseases. With the passage of Proposition 14, Texas is now poised to lead the nation in dementia research and prevention.”

The association says DPRIT will drive scientific breakthroughs, attract top-notch dementia researchers to Texas, and generate thousands of jobs statewide.

An estimated 460,000 Texans are living with dementia, the association says, and more than one million caregivers support them.

DPRIT is modeled after the Cancer Prevention and Research Institute of Texas (CPRIT). Since 2008, the state agency has awarded nearly $4 billion in grants to research organizations for cancer-related academic research, prevention programs, and product development.

An analysis by the McKinsey Health Institute found that investing in brain health initiatives like DPRIT could boost Texas’ GDP by $260 billion. Much of that GDP bump could benefit the Houston area, which is home to dementia-focused organizations such as UTHealth Houston Neurosciences, Baylor College of Medicine’s Center for Alzheimer’s and Neurodegenerative Diseases, the University of Texas Medical Branch at Galveston’s Collaborative Alzheimer’s Disease and Memory Disorders Program, and the Houston Methodist Research Institute’s John M. O’Quinn Foundation Neurodegenerative Disorders Laboratory.

The Greater Houston Partnership says DPRIT holds the potential “to elevate Texas — particularly Houston — as a hub for brain health research.”

State Sen. Joan Huffman, a Houston Republican, is one of DPRIT’s champions. She sponsored legislation this year to create the institute and ask Texas voters to approve the $3 billion in funding.

“By establishing the Dementia Prevention and Research Institute of Texas, we are positioning our state to lead the charge against one of the most devastating health challenges of our time,” Huffman said in May. “With $3 billion in funding over the next decade, we will drive critical research, develop new strategies for prevention and treatment, and support our health care community.”
