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.

Austin company to bring AI-powered school to The Woodlands

AI education

Austin-based Alpha School, which operates AI-powered private schools, is opening its first Houston-area location in The Woodlands.

The 8,000-square-foot school, scheduled to be ready for the 2026-27 academic year, initially will serve students in kindergarten through eighth grade. Alpha says the school will offer “open workshop spaces and innovative classrooms that support personalized instruction, core academics, leadership development, and real-world life skills.”

Alpha sets aside two hours each school day for the AI-driven, self-paced study of core subjects like math, reading and science. The rest of each school day consists of life-skills workshops focusing on topics such as leadership and financial literacy.

Alpha’s school in The Woodlands has begun accepting applications for the 2026-27 school year. Annual tuition costs $40,000.

“The Woodlands is one of the most dynamic, forward-thinking communities in Texas, and Alpha is proud to bring

an innovative educational model that complements its strong academic foundation,” says Rachel Goodlad, head

of expansion for Alpha.

Founded in 2014, Alpha School combines adaptive technology-driven instruction with immersive life-skills workshops. Its model emphasizes mastery-based learning in core subjects alongside development of communication, critical thinking, financial literacy and leadership skills. It operates more than 15 schools across the country.

Elsewhere in Texas, Alpha operates schools in Austin, Brownsville, Fort Worth and Plano. Alpha also operates 12 Texas Sports Academy campuses in Texas, including locations in Houston, Pearland and Richmond, along with a NextGen Academy esports school in Austin, a school for gifted students in Georgetown, and lower-cost Nova Academy campuses in Austin and Bastrop.

Alpha has fans and critics. While supporters tout students’ high achievement rates, detractors complain about the high tuition and the AI-influenced depersonalization of education.

“Students and our country need to be in relationship with other human beings,” Randi Weingarten, president of the American Federation of Teachers, a teachers union, tells The New York Times. “When you have a school that is strictly AI, it is violating that core precept of the human endeavor and of education.”

Alpha co-founder MacKenzie Price, a podcaster and social media influencer, doesn’t share Weingarten’s views.

“Parents and teachers: We need to embrace this change,” Price wrote after President Trump signed an executive order promoting AI in schools.

The Times notes that Alpha doesn’t employ AI as a tutor or a supplement. Rather, the newspaper says, AI is “the school’s primary educational driver to move students through academic content.”

Houston researcher secures $1.7M to develop drug for aggressive form of breast cancer

cancer research

A University of Houston researcher has joined a $3.2 million effort to develop a new drug designed to attack a cancer-driving protein commonly found in triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is one of the most difficult-to-treat forms of cancer and accounts for 10 percent to 15 percent of all breast cancer cases. The disease gets its name because tumors associated with it test negative for estrogen receptors, progesterone receptors and excess HER2 protein, making it difficult to target. Due to this, TNBC is often treated with general chemotherapy, which can come with negative side effects and drug resistance, according to UH.

UH College of Pharmacy research associate professor Wei Wang is developing a drug that can target the disease more specifically. The drug will target MDM2, a protein often overproduced in TNBC that also contributes to faster tumor growth.

Wang is working on a team led by Wei Li, director of the University of Tennessee Health Science Center College of Pharmacy’s Drug Discovery Center. She has received $1.7 million to support the research.

Wang and UH professor of pharmacology and toxicology Ruiwen Zhang have discovered a compound that can break down MDM2. In early laboratory models, the compound has shown the ability to shrink tumors.

Wang and Zhang will focus on understanding how the treatment works and monitoring its effectiveness in models that closely mirror human disease.

“We will study how the drug targets MDM2 and evaluate the most promising drug candidates to determine effective dosing, understand how the drug behaves in the body, compare it with existing treatments and assess early safety,” Wang said in a news release.

Li’s team at the University of Tennessee will be working on the chemistry and drug design end of the project.

“This work could lead to an entirely new class of therapies for triple-negative breast cancer,” Li added in the release. “We’re hopeful that by directly removing the MDM2 protein from cancer cells, we can help more patients respond to treatment regardless of their tumor type.”
