Commercializing a health tech innovation is a long game — fraught with regulatory obstacles, cyclical rounds of funding, and continuous improvement — all fueled by the desire to enhance treatment and save lives.

That's Tim Boire's plan. And it's a thorough one at that. On this week's episode of the Houston Innovators Podcast, Boire — president and CEO of VenoStent, a medical device startup that’s designing a unique material for hemodialysis patients — shares his roadmap for his company.

"We believe we can be pioneers of a paradigm shift in vascular surgery — to not just treat problems after they've already occurred, but actually prevent them from occurring in the first place," he says in the episode.

VenoStent's most recent hurdle cleared is closing a $16 million series A round of venture funding. Two Charleston, South Carolina-based firms — Good Growth Capital and IAG Capital Partners — led the round. The TMC Venture Fund also contributed.

Now, VenoStent is headed for a 200-patient trial in the United States, with an ultimate goal of product launch in 2026. The company's unique medical device is a bioabsorbable wrap that reduces vein collapse by providing mechanical support and promoting outward vein growth.

Boire had the idea for VenoStend when he was completing his PhD at Vanderbilt University. He completed the program, and then joined the HealthWildcatters accelerator in 2017 in Dallas. After that, Boire and his co-founder, Geoff Lucks, decided to take the leap and move to Houston to join JLABS at TMC. The rest, as they say, is history.

“Houston’s been a great place to hire,” Boire says. “We've been I think very fortunate to find our employees who are stellar, true believers in the technology — amazing engineers, and amazing people.”

And, of course, Boire has a plan to continue this hiring success. He says the goal is to grow to a team of 16 by the end of the year. Marketing and sales roles will likely be filled in 2025 ahead of product launch.

“When we think about what our mission is at VenoStent, it’s to ultimately improve patient care — and we are very passionate about this specific problem that patients experience and go through,” Boire says.

“That's what drives everything we're doing as a company to improve quality and length of life for patients who have chronic kidney disease that progresses to a point where they need dialysis to sustain life," he continues. "We believe that we can become the standard care for vascular surgery starting with hemodialysis access."

As VenoStent's trials and growth goes according to plan, Boire says this product can be used for other implications.

Boire shares more on his grand plan, plus how he weathered the storm that is fundraising at a time where so much venture capital activity has slowed. Listen to the interview here — or wherever you stream your podcasts — and subscribe for weekly episodes.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
