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."

Houston biodesign innovators ready to spin out startup with life-saving vascular tech

Yes, you can die of a broken heart — although it's not in the hyperbolic way you might be thinking. Fewer than 20 percent of people who have an aortic aneurysm rupture survive the event. But aortic aneurysms can be treated if they’re caught before they burst. A new Houston company is devoted to a novel solution to helping patients with abdominal aortic aneurysms (AAA).

That company is Taurus Vascular. As part of the current class of the TMC Innovation Biodesign Program, fellows Matthew Kuhn and Melanie Lowther were tasked with creating a biomedical company in a year. The founders started their journey last August. At the end of this month, they'll be kicked out of the nest, Kuhn tells InnovationMap. Taurus is also in Rice University's 2023 cohort of OwlSpark, an ongoing summer program for startups founders from the Rice community.

Kuhn is a biomedical engineer who just scored his forty-fifth patent. The CEO says that he hit it off quickly with his co-founder and COO, Lowther, former director entrepreneurship and innovation at Texas Children’s Hospital.

Members of the Biodesign Program are paid a livable stipend to devote themselves fully to creating a pioneering company. Kuhn says that he became interested in finding a more effective way to heal AAAs during his four and a half years as a project leader at the Center for Device Innovation at the Texas Medical Center.

“It was ripe for innovation and we landed on a concept of some merit,” he says.

The current standard of care for AAAs is EVAR, or endovascular aneurysm repair, in which a surgeon inserts a stent to relieve pressure on the aneurysm.

“It used to be if you had a AAA, you had a gnarly procedure,” he says, which included a large incision across the abdomen. EVAR eliminated that, but its problem is that it often results in endoleaks. As many as 20 percent of patients need another EVAR within five years.

Taurus Vascular’s technology improves on EVAR by placing a self-deploying stent to create a drainage pathway between the high-pressure aneurysm sac and a low-pressure nearby vein — mitigating the adverse impact of endoleaks that would otherwise cause the aneurysm to continue to grow. The simple solution will allow patients to live longer, healthier lives after their procedure.

Kuhn says that being in Houston has been and will continue to be instrumental in his company’s success. Part of that, of course, is his relatively cosseted status as a founder in the Innovation Biodesign Program. But he says that the industry as a whole has become almost like a family.

“It feels very different from startup life for other industries where it feels competitive,” he explains. "You have to be a little crazy to start a medical device company and there’s a sense that we’re all in the same boat. People are so generous with their time to share resources. I feels like I have 100 co-founders."

Following the end of Taurus Vascular’s time in the program that helped conceived it, its founders will remain in the same building, continuing to work to support their technology. The next step is raising a seed round that will pay for the company’s chronic animal studies. Because Taurus Vascular is producing a Class III medical device, its approval process to get to market is the most stringent the FDA has.

The goal is to be commercial by 2030, says Kuhn. By then, Taurus Vascular will have healed many a heart.

Sandbox VR brings new gaming center to Houston's tech-savvy population

Get In The Game

Sandbox VR, a futuristic, full-body virtual reality gaming experience, has announced it will enter the Houston market this month, opening its first local gaming center on January 23.

"Houston's reputation as a hub for innovation and technology makes it a perfect fit for Sandbox VR," said Steve Zhao, CEO and founder of Sandbox VR, in a statement. "The city's diverse, tech-savvy population and strong entertainment culture create an ideal environment for our immersive VR experiences. LOL Entertainment continues to exceed our expectations as a partner, and we're excited to bring our cutting-edge virtual reality gaming to Texas's largest city."

The new gaming center opens Friday, January 23 at 797 Sorella Court in CityCentre.

One of the games that stands out is the Stranger Things: Catalyst game, based on the blockbuster Netflix television series. Groups of one to six players will be dropped into the sinister Hawkins Lab and the mysterious Upside Down to fight Demogorgons and other monsters. The game features Matthew Modine reprising his role as Dr. Martin "Papa" Brenner, who imbues players with psychic powers.

Baylor College of Medicine names Minnesota med school dean as new president, CEO ​

new leader

Dr. Jakub Tolar, dean of the University of Minnesota Medical School, is taking over as president, CEO and executive dean of Houston’s Baylor College of Medicine on July 1.

Tolar—who’s also vice president for clinical affairs at the University of Minnesota and a university professor—will succeed Dr. Paul Klotman as head of BCM. Klotman is retiring June 30 after leading Texas’ top-ranked medical school since 2010.

In tandem with medical facilities such as Baylor St. Luke’s Medical Center and Texas Children’s Hospital, Baylor trains nearly half of the doctors who work at Texas Medical Center. In addition, Baylor is home to the Dan L Duncan Comprehensive Cancer Center and the Texas Heart Institute.

The hunt for a new leader at Baylor yielded 179 candidates. The medical school’s search firm interviewed 44 candidates, and the pool was narrowed to 10 contenders who were interviewed by the Board of Trustees’ search committee. The full board then interviewed the four finalists, including Tolar.

Greg Brenneman, chair of Baylor’s board and the search committee, says Tolar is “highly accomplished” in the core elements of the medical school’s mission: research, patient care, education and community service.

“Baylor is phenomenal. Baylor is a superpower in academic medicine,” Tolar, a native of the Czech Republic, says in a YouTube video filmed at the medical school. “And everything comes together here because science saves lives. That is the superpower.”

Tolar’s medical specialties include pediatric blood and bone marrow transplants. His research, which he’ll continue at Baylor, focuses on developing cellular therapies for rare genetic disorders. In the research arena, he’s known for his care of patients with recessive dystrophic epidermolysis bullosa, a severe genetic skin disorder.

In a news release, Tolar praises Baylor’s “achievements and foundation,” as well as the school’s potential to advance medicine and health care in “new and impactful ways.”

The Baylor College of Medicine employs more than 9,300 full-time faculty and staff. For the 2025-26 academic year, nearly 1,800 students are enrolled in the School of Medicine, Graduate School of Biomedical Sciences and School of Health Professions. Its M.D. program operates campuses in Houston and Temple.

In the fiscal year that ended June 30, 2024, Baylor recorded $2.72 billion in operating revenue and $2.76 billion in operating expenses.

The college was founded in 1900 in Dallas and relocated to Houston in 1943. It was affiliated with Baylor University in Waco from 1903 to 1969.
