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.

2 leading Texas universities rank among world’s best for entrepreneurs

honor roll

The Lone Star State’s two biggest universities—the University of Texas at Austin and Texas A&M University—rank among the world’s best schools for entrepreneurs.

PitchBook’s annual list of the world’s top 100 universities for entrepreneurs takes into account both undergraduate and graduate programs. PitchBook analyzed more than 222,000 startup founders whose startups are VC-backed.

UT’s “unique” advantage

UT Austin landed at No. 10 on the list, down from No. 8 last year. PitchBook identified 1,002 UT-alumni founders at 948 startups. Collectively, those startups have raised $34.7 billion, according to PitchBook.

Among the 948 UT Austin-affiliated startups, these five have raised the most capital:

  • No. 1 Tucson, Arizona-based World View, $2.8 billion
  • No. 2 Austin-based Apptronik, $966 million
  • No. 3 Mountain View, California-based Lightmatter, $821 million
  • No. 4 Austin-based Function Health, $807 million
  • No. 5. San Francisco-based Niantic, $779 million

“The unique UT Austin advantage is the alignment between the university and the city,” Foundra.ai says. “Unlike schools where the campus ecosystem and the local startup scene are disconnected, Austin’s startup community actively recruits UT students and alumni, and UT programs actively send students into the local ecosystem.”

Texas A&M’s “living laboratory”

UT Austin’s biggest in-state rival, Texas A&M, appeared at No. 79 on the list, down from No. 76 last year. PitchBook tallied 317 A&M-alumni founders at 295 startups. Collectively, those startups have raised $9.8 billion, according to PitchBook.

Among the 317 A&M-affiliated startups, these five have raised the most capital:

  • No. 1 Austin-based RigUp, $817 million
  • No. 2 Austin-based ICON, $543 million
  • No. 3 Scottsdale, Arizona-based HomeLight, $413 million
  • No. 4 Everett, Washington-based Zap Energy, $326 million
  • No. 5 San Diego-based Splice Therapeutics, $320 million

A cornerstone of Texas A&M’s entrepreneurship offerings is the Center for Applied Entrepreneurship and Innovation at the Mays School of Business. The business school says the center “helps students explore, test, build, buy, and transform businesses in real markets.”

“Grounded in Texas as a living laboratory and guided by the Aggie core values, the center advances applied learning through industry engagement, AI-enabled experimentation, and collaboration across Mays and Texas A&M,” the business school says.

The most “exceptional” schools on PitchBook’s list

In announcing its rankings, PitchBook said: “Great entrepreneurs can come from anywhere, but some universities have a truly exceptional track record of attracting and producing future founders.”

The most exceptional universities, based on PitchBook’s criteria, are:

  • No. 1 University of California, Berkeley
  • No. 2 Stanford University
  • No. 3 Harvard University
  • No. 4 Cornell University
  • No. 5 Massachusetts Institute of Technology (MIT)

Planned KBR spinoff scores $1B NOAA deal for extreme weather forecasting

weather watch

Amid a major spinoff, Houston-based KBR's Mission Technology Solutions business has been awarded a five-year contract for up to $1.1 billion from NOAA’s National Weather Service to help predict and combat extreme weather conditions.

Under the follow-on Commercial Data Program National Mesonet Program (CDP NMP) contract, KBR will provide weather and observational data from commercial stations, university and research campuses, and other non-federal providers nationwide. The information collected will assist in predicting severe temperatures and high-impact weather conditions like extreme storms.

"This award underscores KBR's proven track record of delivering vital data that strengthens national forecasting capabilities," Todd May, KBR’s senior vice president of Mission Technology Solutions, said in a news release.

According to a separate release from NOAA, the contract expands upon KBR's existing relationship with the agency. KBR will work with about 70 private industry partners on services such as data recording, collection, aggregation and processing, and will lead the CDP NMP's "network of networks."

“NOAA gathers environmental information from a wide variety of sources, and a growing list of private industry partners have joined our agency to collect this vital data,” Ken Graham, director of NOAA’s National Weather Service, said in the release. “This agreement streamlines the process that turns raw data into the gold-standard forecasts that Americans depend on.”

KBR will utilize its Speed to Mission ImpactSM technology for the project to supply data from across regions, measurement types, and system configurations. Both KBR and NOAA say the expanded data collection contract will help the agency create more accurate and timely forecasts, particularly for severe weather and extreme events, while also creating a path for new weather-observation technologies.

KBR has supported the CDP NMP for more than 9 years. The program will be managed in Greenbelt, Maryland.

"We're driving expanded integration of commercial sensor and data sources into this platform and are honored to know our work helps forecasters give their communities earlier warnings and more time to prepare for dangerous weather,” May added in a release.

KBR’s Mission Technology Solutions business will be rebranded as Trinzic after its planned spin-off, the company announced last month. The spin-off is expected to close in January 2027.

Trinzic will work as an independent, publicly traded company focused on technology and engineering services for the space and national security sector. KBR will remain a separate publicly traded company that will focus on sustainable technology and services to support the energy transition.

This is the salary required to live comfortably in Texas in 2026

Money Matters

A new national report looking at the income it takes to live comfortably in each of the 50 states has revealed Texans need to earn slightly less now than a year ago.

SmartAsset analyzed what a single individual, as well as family of four, must earn to cover minimum basic needs adjusted using the 50/30/20 budgeting rule. The resulting estimate represents the annual, pre-tax income needed to live comfortably in every U.S. state.

A single, full-time worker needs to make $90,563 to live comfortably in the Lone Star State, the report found, which is down a meager 0.2 percent from last year ($90,771).

Under the 50/30/20 budgeting strategy, that means a single Texas earner would have $45,282 to spend on necessities like housing and utilities, $27,169 for discretionary spending, and $18,113 for emergencies or retirement savings.

Texas ranked 34th nationally in SmartAsset's list of states with the highest income needed for a single adult to live "in sustainable comfort" in 2026. Only five other states — Tennessee, Maryland, Louisiana, North Carolina, and Mississippi — saw a decline in the income needed to live comfortably this year.

For a family of four to live comfortably in Texas, income requirements change significantly, according to the findings. To support a two-child household, a family needs $203,424 in combined total household income to be considered financially stable. This is down slightly from 2025, when SmartAsset reported a family of four in needed $204,922 to live comfortably in Texas.

This is a comfortable lifestyle for a family of four in Texas, according to the report:

  • $101,712 dedicated to necessities and living expenses
  • $61,027 dedicated to discretionary spending
  • $40,685 dedicated to emergencies, savings, or debt repaymen

According to the report, a family of four now needs to make at least $200,000 to live comfortably in 40 U.S. states, a figure that is far out of reach for many American families.

"As housing, grocery, transportation and other essential costs pressure household budgets, earning a six-figure salary no longer guarantees financial comfort in much of the U.S.," the report said. "A single adult now needs at least $80,000 a year to live comfortably in every state, while the threshold exceeds $100,000 in nearly half of states. For a family of four, the income needed to live comfortably is as much as $329,000."

Still, earning the minimum income to live comfortably in Texas doesn't guarantee financial stability in the Lone Star State's major cities. Earlier this year, SmartAsset determined single residents in Houston need to make about $90,000 to qualify as financially stable, while families of four need around $205,000.
