Why this Houston medical device innovator is pumped up for the first total artificial heart

HOUSTON INNOVATORS PODCAST EPISODE 248

It's hard to understate the impact Dr. William Cohn has had on cardiovascular health as a surgeon at the Texas Heart Institute or on health care innovation as the director of the Center for Device Innovation at the Texas Medical Center. However, his role as chief medical officer of BiVACOR might be his most significant contribution to health care yet.

The company's Total Artificial Heart is unlike any cardiovascular device that's existed, Cohn explains on the Houston Innovators Podcast. While most devices are used temporarily for patients awaiting a heart transplant, BiVACOR's TAH has the potential to be a permanent solution for the 200,000 patients who die of heart failure annually. Last year, only around 4,000 patients were able to receive heart transplants.

"Artificial hearts historically have had bladders that ejected and filled 144,000 times a day. They work great for temporary support, but no one is suggesting they are permanent devices," Cohn says on the show.

The difference with BiVACOR's device is it abandons the bladder approach. Cohn explains that as assist pumps evolved — something his colleague, Dr. Bud Frasier, had a huge impact on — they featured new turbine and rotor technology. Daniel Timms, BiVACOR's founder and CTO, iterated on this technology beginning when he was a postdoctoral student at Queensland University of Technology in Australia.

"BiVACOR is the first artificial heart that leverages what we learned from that whole period — it has no bladders, it has no valves. It has one moving part, and that moving part is suspended in an electromagnetic field controlled by a computer and changed thousands of times a second," Cohn says. "It will never wear out, and that's why we think it's the world's first total artificial heart."

The company is seeing momentum, celebrating its first successful human implantation last month. The device was used for eight days on a patient at Baylor St. Luke’s Medical Center before the patient received a heart transplant.

Cohn says that BiVACOR has plans to use the TAH as "bridge-to-transplant" device in several other surgeries and expects to get FDA approval for that purpose in the next three to four years before working toward clearance for total artificial heart transplants.

Cohn has worked to support medical device startups at CDI at TMC for the seven years it has existed — first under Johnson and Johnson and then under TMC when it took the program over. He describes the center and its location as the ideal place for developing the future of health care, with Houston rising up to compete with regions known for medical device success — both coasts and Minnesota.

"Being in the shadow of the largest medical center on the planet — 106,000 employees show up there every 24 hours," Cohn says, "if you want to innovate, this is the place to do it."

Play it back: How this Houstonian is leading heart health innovation

HOUSTON INNOVATORS PODCAST EPISODE 246

Heart health innovation is at a major moment in history — and Houston is at the center of it.

Last summer, Dr. Joseph Rogers, president and CEO of the Houston-based Texas Heart Institute, joined the Houston Innovators Podcast to share how he came to be at the helm of THI, as well as the incredible technologies the institute is working on to address heart failure, a global epidemic affecting at least 26 million people worldwide, 6.2 million adults in the U.S.

This month, one of THI’s technologies reached a major milestone. BiVACOR, a Houston company successfully implanted the company's first Total Artificial Heart in a human. The device was implanted in the patient on July 9. Eight days later, a donor heart became available and was transplanted into the patient, removing the TAH, establishing the device as a successful bridge-to-heart-transplant solution for patients, THI reported.

In addition to this breakthrough in health tech, THI is focused on addressing Cardiometabolic Syndrome at a new conference on Friday, August 23, in Houston. The full-day symposium will take place in collaboration with Arianna Huffington, the founder and CEO of Thrive Global. Dr. Rogers is co-directing the program with Dr. Stephanie Coulter, medical director for THI Center for Women’s Heart & Vascular Health.

In the episode, Rogers explains why he's bullish on Houston and THI leading heart health innovation alongside other health care organizations — nonprofits, universities, local government — to collaborate in ways never been done before. And THI is dedicated to this mission.

"We should act as a convener," Rogers says. "Houston is the place to do this.

"The reason I think this is such an important community to address this problem is it's the most diverse city in the United States. And I've never lived anywhere or heard of another city that I was so convinced believed they could do anything they set their minds to. It's about making the community aware of the problem and a potential solution — and then working on trying to solve it," he continues. "But I think all of the pieces are here to show the world how to do this at a community level."

Houston health care organization to host conference about cardiac health crisis

heartbeat heroes

Cardiometabolic Syndrome (CMS) is a major danger to public health around the world. No one knows this better than the Texas Heart Institute, which will host its first Cardiometabolic Syndrome Conference on Friday, August 23.

The conference’s subtitle, “A population health crisis” brings home the unpleasant reality that many recent projections anticipate drastic growth for the condition.

CMS is a combination of interrelated metabolic maladies that are risk factors not just for cardiovascular disease, but also fatty liver disease and cancer. According to THI, the underlying conditions for CMS may include hypertension, insulin resistance and type II diabetes, elevated serum lipids, and obesity, all increasingly common among the global population.

The conference will address the crisis with the help of Arianna Huffington, the founder and CEO of Thrive Global and former editor in chief of The Huffington Post Media Group. Thrive's behavior change technology may be a possible step in the right direction to prevent CMS.

“We are at a pivotal moment in the fight against cardiometabolic syndrome,” Huffington says in a press release. “This conference is not just a gathering of experts, but a catalyst for innovative thinking and actionable solutions. By integrating diverse perspectives and harnessing the collective expertise of our attendees, we can transform disease prevention strategies and improve health outcomes globally.”

THI experts will both lead the conference and participate in discussions. The co-directors are renowned cardiologists, Dr. Joseph G. Rogers, CEO and president of The Texas Heart Institute, and Dr. Stephanie Coulter, medical director for THI Center for Women’s Heart & Vascular Health. Topics will include screening and treatment guidelines, the impact of CMS on children, and integrating social determinants of health into clinical practice. Health professionals among the attendees will include cardiologists, hepatologists and endocrinologists.

“We must transcend traditional healthcare solutions to effectively tackle the rising burden of cardiometabolic syndrome,” says Rogers. “By bringing together key stakeholders and encouraging collaboration among multidisciplinary healthcare professionals, we aim to ignite groundbreaking ideas and forge novel strategies to combat this pressing health crisis."

Speaking of novel technologies, THI and BiVACOR this month reported that they successfully implanted the company's first Total Artificial Heart in a human at Baylor St. Luke’s Medical Center in the TMC.

The milestone is part of an FDA-approved early feasibility study that will test the safety and performance of the TAH device, which is based on a magnetically levitated rotor that takes over functions of a failing heart while a patient is awaiting a heart transplant, according to a statement from the organizations.

The "bridge-to-transplant" device could support an active adult male, as well as many women and children suffering from severe biventricular heart failure or univentricular heart failure.

BiVACOR received approval from the FDA for the early feasibility study in late 2023 and has four other patients enrolled in the study. At the time the study was approved, 10 hospitals were enrolled as possible sites.

“I’m incredibly proud to witness the successful first-in-human implant of our TAH. This achievement would not have been possible without the courage of our first patient and their family, the dedication of our team, and our expert collaborators at The Texas Heart Institute ... our TAH brings us one step closer to providing a desperately needed option for people with end-stage heart failure who require support while waiting for a heart transplant. I look forward to continuing the next phase of our clinical trial,” Daniel Timms, PhD, founder and CTO of BiVACOR, adds.

About 100,000 patients suffering from severe heart failure could benefit from BiVACOR’s artificial heart, the company says. Globally, only about 6,000 heart transplants are performed each year, while 26 million people worldwide are affected by heart failure.

BiVACOR was founded in 2008 and maintains its headquarters in Houston, along with offices in Huntington Beach, California, and Brisbane, Australia.

To date, the company has raised nearly $50.8 million, according to CB Insights. The company raised $18 million in 2023, and $22 million in 2021.

Earlier this year, BiVACOR named a new CEO in Jim Dillon, a longtime executive in the medical device sector.

Last summer, Rogers joined the Houston Innovators Podcast to share his excitement with THI's innovations.

Italian aerospace company sets up first U.S. office at Houston Spaceport

welcome to houston

Como, Italy-based aerospace company Involve Space recently made the Houston Spaceport the site of its first U.S. office.

Involve Space develops high-altitude balloon platforms for Earth observation, scientific research and hardware testing. The balloons carry instruments into the stratosphere (a layer of the upper atmosphere) to collect images and data, conduct experiments and test technology.

The company plans to launch its first commercial missions from Houston by the end of this year, according to a news release.

“Houston is the global center of aerospace, and our presence at Houston Spaceport strengthens our international growth trajectory,” Jonathan Polotto, founder and CEO of Involve Space, said in the release.

Founded in 2021, Involve Space incorporates aerospace hardware, AI and geospatial tools into its offerings. Its proprietary CLEAR platform uses conversational AI to help customers interpret data and support decision-making.

Located at Ellington Airport, the Houston Spaceport provides a base for Involve Space’s North American operations, including business development and partnerships with aerospace companies and researchers.

Other tenants at the Houston Spaceport include NASA, Axiom Space, Venus Aerospace and Intuitive Machines.

Involve Space’s relationship with the Houston Spaceport began in January 2025, when it conducted its first U.S. pilot launch. During the five-hour mission, the balloon reached an altitude of about 85,000 feet and traveled about 250 miles across Texas.

One of Involve Space’s first U.S. customers is Houston-based Rhodium Scientific, a space biotech company. Polotto and Rhodium Scientific founder and CEO Olivia Gamez Holzhaus signed a deal to conduct biotech experiments aboard Involve Space’s stratospheric balloon platforms before planned missions to orbit.

“The presence of innovative platforms like those developed by Involve strengthens the Spaceport’s role as a site for testing, validating, and deploying advanced technologies between aeronautics and space,” Jim Szczesniak, director of aviation for Houston Airports, added in the release.

UH lands $3M grant to expand opioid overdose training

Overdose Response

The University of Houston has received a $3 million federal grant to expand its potentially life-saving overdose response training program.

The grant will support the Houston Health Department’s FRONTLINES program that trains first responders in Harris and Fort Bend counties to recognize opioid overdoses and administer the drug naloxone, which can counter the effects of an opioid overdose. The four-year grant comes from the Substance Abuse and Mental Health Services Administration within the Department of Health and Human Services, and it builds on eight years of work at UH, according to a release from the university.

As part of the expansion, UH medical, social work and psychology students will now also be able to take part in FRONTLINES’ overdose-response training. Some of the students will also be selected to help train community members, ultimately passing along the life-saving skills throughout Houston.

FRONTLINES is a collaboration with the City of Houston, the Fertitta College of Medicine, Baylor College of Medicine and the Houston Recovery Center. It was co-founded by Dr. James Bray, chair of the Department of Behavioral and Social Sciences at the University of Houston’s Tilman J. Fertitta Family College of Medicine, in 2018.

“When someone experiencing an opioid overdose is reached in time, naloxone can save their life,” Bray said in a news release. “We’ve seen the impact this training can have in Houston, and now we have an opportunity to extend that reach across Harris and Fort Bend counties, putting lifesaving knowledge and tools into the hands of more first responders.”

In 2024, around 450 residents of Harris County died from opioid overdoses, according to a Texas Department of State Health Services report. The report found that fentanyl was involved in about three-quarters of the deaths.

In 2025, UH also received a $2.6 million gift from the estate of Dr. William A. Gibson to expand its opioid research and develop a vaccine to help block fentanyl's effectiveness in entering the brain. The vaccine research is part of the Michael C. Gibson Addiction Research Program led by UH professor of psychology Therese Kosten and founding member of the UH Drug Discovery Institute Colin Haile.

Texas public libraries drive billions in economic impact, report finds

Beyond the Stacks

A new statewide study examining the economic impacts of public libraries has revealed they have generated over $3.8 billion in value to local communities — a return of $4.74 for every $1 invested.

The report, "Beyond the Stacks: Measuring the Economic and Community Value of Texas Public Libraries" was conducted by third-party consultancy JBK Economics Group in partnership with the Texas Library Association. About 300 of the total 513 public libraries in Texas participated in a survey for the report.

A major finding from the survey revealed that public libraries create billions in economic value for the communities they serve at a fraction of what it costs to pay employee wages and benefits, operating expenditures, and capital expenditures. About 11,200 jobs were directly and indirectly supported by public libraries, the report found.

The report found its $4.74 to $1 ratio by adding up the total value of the services provided by these institutions (an estimated $2.48 billion), and comparing it to total expenditures ($808.6 million).

"Public libraries had about the same economic footprint as the Texas motion picture and sound recording industry ($2.9 billion in Gross Domestic Product in 2024) or the Texas paper manufacturing industry ($4.0 billion in Gross Domestic Product in 2024)," the report said.

Many Houstonians are already familiar with Houston Public Library's expansive catalog and programming, but there are many more services the library provides that might fly under the radar. A few examples include access to subscription-based research databases and news outlets, and the Library of Things, a collection of cookware and bake ware, musical instruments, craft kits, and other tools or activity materials that are available for cardholders to borrow. Individual branches also provide free Wi-Fi, computer access, and meeting spaces.

Houston-area residents also have access to services at several other local libraries depending on their address, such as the Harris County Public Library, Montgomery County Memorial Library System, or Fort Bend County Libraries, just to name a few.

These are additional services and partnerships that Texas public libraries commonly provide, per the survey results:

93 percent provide voter registration and/or serve as voting locations
84 percent provide partnerships with local social services agencies
82 percent provide job application assistance
68 percent facilitate applications for government benefits
38 percent provide on-site social services
30 percent provide telehealth rooms and/or resources

"Public libraries are practical, welcoming and rooted in the communities they serve — they are unmistakably Texan," said Texas Library Association executive director Shirley Robinson in a press release. "This study puts a dollar value on the opportunities libraries create every day. Whether someone visits a library to apply for a job, access the internet, learn a new skill or simply find a new favorite book, those services create real value for Texans and their communities."
