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.

Persona AI teams with Under Armour to protect next-gen robots

Future Fabrics

Houston-based Persona AI has cemented a partnership with sportswear manufacturer Under Armour to provide materials to protect future robots operating in dangerous conditions.

Through the partnership, Persona AI and Under Armour will launch a research initiative to explore whether advanced performance textiles can improve the durability and resilience of humanoid robots operating in harsh industrial environments.

“This is an opportunity to apply our innovation expertise in a new context,” Kyle Blakely, senior vice president of innovation, design studio, development, and testing at Under Armour, said in a news release. “Robotics presents a fascinating new design challenge, and we aim to play a leading role in shaping performance solutions for these environments. As humanoid systems take on more physically demanding roles, we see real potential to create new market opportunities, and we’re exploring how concepts like thermal management, abrasion resistance, and flexibility translate beyond sport."

Founded in June 2024 by former NASA engineer Nicolaus Radford and former Figure AI CTO Jerry Pratt, Persona AI has quickly risen to be a top name in the development of humanoid robotic systems. Radford previously was the principal investigator at NASA’s Dexterous Robotics Lab before becoming CEO of Nauticus Robotics. While at NASA, he was the chief engineer behind Robotnaut 2, the first humanoid robot on the International Space Station.

Persona AI raised $25 million in preseed funding to develop humanoid robots designed to operate in shipyards and other industrial sites. The company has inked partnerships with HD Korea Shipbuilding & Offshore Engineering, HD Hyundai Robotic, and Korean manufacturing firm Vazil Company to create and deploy humanoid robots for complex welding tasks in shipyards.

These environments often involve exposure to dangerous chemicals, harsh weather and other potential hazards. The partnership between Persona AI and Under Armour will combine the clothing manufacturer’s development of resilient but flexible materials with the humanoid design of Persona AI.

Though best known for its sportswear, Under Armour produces a wide range of specialist fabrics and clothing, including an entire line used by the U.S. military. The company’s track record of developing high-performance fabrics built to withstand war zones and desert conditions makes it a strong partner in Persona AI’s latest endeavor.

“We chose to work with Under Armour because of their track record of innovation with these types of performance materials,” Radford said. “As we develop humanoids for intense and potentially hazardous environments, this collaboration helps us understand how advanced materials can enhance long-term reliability, thereby informing solutions to better protect workers in the field.”

Texas solar power poised to surpass coal for the first time in 2026

Powering Texas

Solar power promises to shine even brighter in Texas this year.

A new forecast from the U.S. Energy Information Administration (EIA) indicates that for the first time, annual power generation from utility-scale solar will surpass annual power generation from coal across the territory covered by the Electric Reliability Council of Texas (ERCOT).

Solar generation is expected to reach 78 billion kilowatt-hours in 2026 in the ERCOT grid, compared with 60 billion kilowatt-hours for coal, the EIA forecast says. The ERCOT grid supplies power to about 90 percent of Texas, including the Houston area.

“Utility-scale solar generation has been increasing steadily in ERCOT as solar capacity additions help meet rapid electricity demand growth,” the forecast says.

Although natural gas remains the dominant source of electricity generation in ERCOT, accounting for an average 44 percent of electricity generation from 2021 to 2025, solar’s share of the generation mix rose from four percent to 12 percent. During the same period, coal’s share dropped from 19 percent to 13 percent.

EIA predicts about 40 percent of U.S. solar capacity, or 14 billion kilowatt-hours, added in 2026 will come from Texas.

Although EIA expects annual solar generation to exceed annual coal generation in 2026, solar surpassed coal in ERCOT on a monthly basis for the first time in March 2025, when solar generation totaled 4.33 billion kilowatt-hours and coal’s totaled 4.16 billion kilowatt-hours. Solar generation continued to exceed that of coal until August of that year.

“In 2026, we estimate that solar exceeded coal for the first time in March, and we forecast generation from solar installations in ERCOT will continue to exceed that from coal until December, when coal generation exceeds solar,” says EIA. “We expect solar generation to exceed that of coal for every month in 2027 except January and December.”

For 2027, EIA forecasts annual solar generation of 99 billion kilowatt-hours in the ERCOT grid, compared with 66 billion kilowatt-hours of annual coal generation.

In April, ERCOT projected almost 368 billion kilowatt-hours of demand in ERCOT’s territory by 2032. ERCOT’s all-time peak demand hit 85.5 billion kilowatt-hours in August 2023.

“Texas is experiencing exceptional growth and development, which is reshaping how large load demand is identified, verified, and incorporated into long-term planning,” ERCOT President and CEO Pablo Vegas said. “As a result of a changing landscape, we believe this forecast to be higher than expected … load growth.”
