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.

Houston space tech co. rolls out futuristic lunar rover for NASA's Artemis missions

to the moon

Houston-based space exploration company Intuitive Machines just unveiled its version of a lunar terrain vehicle that’s designed to be used by astronauts in NASA’s Artemis moon discovery program.

Intuitive Machine recently rolled out its RACER lunar terrain vehicle (LTV) at Space Center Houston. RACER stands for Reusable Autonomous Crewed Exploration Rover.

The rover can accommodate two astronauts and nearly 900 pounds of cargo. In addition, it can pull a trailer loaded with almost 1,800 pounds of cargo.

Intuitive Machines will retain ownership and operational capabilities that will enable remote operation of the LTV between Artemis missions for about 10 years.

NASA chose Intuitive Machines and two other companies to develop advanced LTV capabilities.

“The objective is to enable Artemis astronauts, like the Apollo-era moonwalkers before them, to drive the rover, which features a rechargeable electric battery and a robotic arm, across the lunar surface, to conduct scientific research and prepare for human missions to Mars,” Intuitive Machines says in a post on its website.

The company tapped the expertise of Apollo-era moonwalkers Charlie Duke and Harrison Schmitt to design the pickup-truck-sized RACER. Intuitive Machines engineered the LTV in partnership with Atlas Devices, AVL, Barrios, Boeing, CSIRO, FUGRO, Michelin, Northrop Grumman, and Roush.

“This [project] strategically aligns with the Company’s flight-proven capability to deliver payloads to the surface of the Moon under [NASA’s] Commercial Lunar Payload Services initiative, further solidifying our position as a proven commercial contractor in lunar exploration,” says Steve Altemus, CEO of Intuitive Machines.

Astronauts at NASA’s Johnson Space Center are testing the static prototype of the company’s LTV. Meanwhile, the fully electric mobile demonstration LTV will undergo field testing later this month near Meteor Crater National Park in Arizona.

NASA expects to choose an LTV provider or providers in 2025.
