Houston-based PolyVascular, which develops minimally invasive solutions for children with congenital heart disease, was named the overall winner of the American Heart Association’s annual Health Tech Competition earlier this month.

The company was founded in 2014 by Dr. Henri Justino and Daniel Harrington and was part of TMCi's 2017 medical device cohort. It is developing the first polymer-based transcatheter pulmonary valve designed specifically for young children, allowing for precise sizing and redilation as the child grows while also avoiding degradation. PolyVascular has completed preclinical studies and is working toward regulatory submissions, an early feasibility study and its first-in-human clinical trial thanks to a recent SBIR grant from the National Heart, Lung, and Blood Institute.

With the new AHA honor, PolyVascular will be invited to join the association’s Center for Health Technology & Innovation Innovators’ Network, which connects entrepreneurs, providers and researchers to share and advance innovation in cardiovascular and brain health.

“This is a tremendous honor for PolyVascular—we’re especially proud to bring hope to families and children living with congenital heart defects,” Justino said in a news release. “Our technology—a minimally invasive valve that can be expanded over time to grow with the child—has the potential to dramatically reduce the need for repeated open-heart surgeries.”

The Health Tech Competition is a live forum for health care innovators to present their digital solutions for treating or preventing cardiovascular diseases and stroke.

Finalists from around the world addressed heart failure, hypertension, congenital heart defects and other issues that exist in cardiovascular, brain and metabolic health. Solutions were evaluated on the criteria of validity, scientific rigor and impact.

The judges included Texas-based Dr. Eric D. Peterson, professor of medicine in the division of cardiology at UT Southwestern Medical Center, and Dr. Asif Ali, clinical associate professor of cardiovascular medicine at the University of Texas Medical School in Houston and director at Cena Research Institute.

According to the American Heart Association, nearly half of U.S. adults live with some form of cardiovascular disease or stroke.

“The American Heart Association plays a pivotal role in advancing innovative care pathways, and we’re excited that our solution aligns with its guidelines and mission,” Justino said in a news release. “It’s time these life-changing technologies reach the youngest patients, just as they already do for adults.”

New innovation hub grows with the addition of 6 Houston startups

moving in

The East End Maker Hub in Houston's East End District is growing with the recent addition of six startups.

"All of these companies cite the East End Maker Hub's physical innovation infrastructure, customizable spaces, strategic location, and potential collaborators as motivations for moving their operations into the hub," Patrick Ezzell, president of Urban Partnerships Community Development Corp., one of the hub's creators, says in an April 26 news release. "All are in the process of growing their teams and view Houston and, more specifically, the East End as a key resource for human capital heading into the future."

The companies that recently joined the East End Maker Hub are:

Alchemy Industrial. The company is a contract manufacturer that uses advanced technologies to develop industrial products for the medical, renewable energy, and drone sectors. Mush Khan, a British-born entrepreneur, established the startup last year.
CarbonATM. Led by Frank Zamarron and a group of former NASA engineers, CarbonATM aims to improve monitoring of ambient air quality with a low-cost portable device.
Gbowo Inc. This startup, founded in 2020, seeks to help companies reduce the environmental and financial costs of last-mile deliveries through the use of low-speed electrical vehicles. Ganiu Ladejobi is the founder and CEO.
Horizon Aeromarine. Established in 2020, the startup develops software and electronics from unmanned aerial and marine vehicles. Laura Sammons and Denver Hopkins are the founders.
Parallax 621. Founded by Benjamin Peters and Phillip Lentz, the Parallax 621 tech think tank develops technology based on theoretical physics research.
Polyvascular. The startup, established in 2014, makes a polymer-based heart valve for children with congenital heart disease.

The East End Maker Hub, at 6501 Navigation Blvd., is a collaboration between TXRX Labs and Urban Partnerships Community Development that houses crafters, fabricators, and tech manufacturers. TXRX Labs invested $1.25 million in equity to set up the hub. Urban Partnerships Community Development raised $35.75 million in capital to get the project off the ground.

Houston startup with life-saving innovation receives $2M grant

for the children

A $2 million federal grant will enable Houston-based PolyVascular to launch human trials of what it hails as the first polymer-based heart valve for children.

In conjunction with the grant, Dr. Will Clifton has joined the medical device company as chief operating officer. He will oversee the grant as principal investigator, and will manage the company's operations and R&D. Clifton is president and co-founder of Houston-based Enventure, a medical innovation incubator and education hub. He previously was senior director of medical affairs at Houston-based Procyrion, a clinical-stage medical device company.

PolyVascular's Phase II grant came from the Small Business Innovation Research (SBIR) program, which promotes technological projects.

The PolyVascular heart valve will help treat congenital heart disease affecting more than 1 million around the world. PolyVascular plans to launch clinical trials of the valve in children 5 and over within two years.

"Congenital heart disease remains the most common category of birth defect and a leading cause of childhood death in the developed world," reads a March 30 news release from PolyVascular, founded in 2014.

PolyVascular says the valve can be implanted without surgery, and can avoid the use of valve replacements from humans or animals. Those valve replacements are difficult to find and often don't last too long, leading to frequent follow-up surgeries.

"Our aim at PolyVascular is to transform the care of children with congenital heart disease by developing an entirely new generation of valves made of medical-grade polymer devoid of any biological tissue," Dr. Henri Justino, chief medical officer at PolyVascular, says in a release. "The valves in use so far for children have been made of biological tissue. Unfortunately, our immune systems target and destroy this biological tissue, sometimes rapidly, rendering the valve ineffective."

The SBIR grant isn't the only win for PolyVascular in recent years.

In 2019, the startup came away with several honors in the 2019 Texas A&M New Ventures Competition. It won the pitch competition (complete with a $5,000 cash award), and received the Biotex Investment Prize, Amerra Visualization Services Prize, and GOOSE Society Investment Prize.

Also in 2019, PolyVascular, a member of TMCx's 2017 medical device cohort, won in the medical device and health disparities and equity categories at the fifth annual Impact Pediatric Health pitch competition. Additionally, the Southwest National Pediatric Device Consortium granted the company up to $25,000.

Last year, MedTech Innovator, a nonprofit accelerator in the medical technology sector, announced PolyVascular was one of 50 companies chosen to participate in the organization's flagship four-month accelerator program.

"During these uncertain and challenging times, the need for health innovations — specifically those that promise to deliver long-term value to the health care system and patients — is more critical than ever," said Paul Grand, CEO of MedTech Innovator.

Another Houston startup, Vivante Health, also was picked for the MedTech Innovator program. Vivante is a digital health company that helps people address digestive health and wellness.

2 TMCx companies leave SXSW with awards and grant money

Med tech

Two Houston companies are walking away from SXSW with awards and grant funds.

PolyVascular, a member of TMCx's 2017 medical device cohort, won the fifth annual Impact Pediatric Health pitch competition's medical device and health disparities and equity categories. Additionally, the Southwest National Pediatric Device Consortium granted the company up to $25,000.

PolyVascular co-founder Henri Justino represented his company in three-minute pitch, and team members Dan Harrington and Kwon Soo Chun were also in attendance.

The company was one of 12 finalists in the competition, which took place on March 8 at SXSW in Austin. Among the judges was Houston doctor, Chester Koh, professor of urology, pediatrics, and OB/GYN at Baylor College of Medicine and Pediatric Urologist at Texas Children's Hospital.

"At the Southwest National Pediatric Device Consortium, we are always looking for the next cutting-edge breakthrough in the world of medical devices," says Koh in a release. "Impact Pediatric Health's reputation for bringing together the leaders in pediatric medical technology innovations makes it the perfect venue to help identify and accelerate the next generation of medical device companies impacting our youngest of patients."

Founded in 2014, PolyVascular produces polymeric transcatheter valves for children with congenital heart disease — the most common birth defect and number one cause of infant mortality in the developed world. The company's goal is to reduce that number of infant deaths by introducing a higher quality of valves.

Meanwhile, VastBiome, a 2018 biodesign TMCx company, received a $1,000 grant and is now one of two finalists for the San Francisco-based Illumina Accelerator program. The company works with scientists with ongoing clinical trials focusing on the microbiome as it pertains to therapy.

Another TMCx company, Zibrio, was up for an award in the 2019 SXSW Pitch event, but left the contest empty handed.

TMCx has multiple representatives at the festival, and the organization partnered with Energizing Health to host events throughout the first weekend of the conference.

UTMB launches new department for space medicine, names inaugural leader

department launch

In space, no one can hear you scream—but they can hear you discuss your medical history and recent symptoms.

The University of Texas Medical Branch (UTMB) announced last month that it would form a new Department of Aerospace and Exploration Medicine within its School of Public and Population Health under the leadership of Dr. Ronak V. Shah, who will serve as inaugural chair.

“Human exploration is changing rapidly, and the health challenges associated with distance, isolation, and limited resources are changing along with it,” Shah said in a news release. “Creating the Department of Aerospace and Exploration Medicine gives us an opportunity to build on decades of expertise at UTMB as we prepare for the future.”

The new department elevates UTMB’s existing Aerospace Medicine Division and provides "broader academic structure for expanding research, education, and collaboration across disciplines," according to the release. Shah was previously named director of the division in 2022 after serving as medical director of Johnson Space Center.

Space exploration in particular has a wide variety of highly specific medical side effects that are in need of the formalized study that the department will specialize in. For example, zero- and low-gravity environments cause everything from detached fingernails to flattened eyeballs. Even in modern, high-tech spacecraft, the human body feels the impacts of space.

It’s an area of medicine UTMB is uniquely suited for. Starting in the 1950s with NASA’s director of medical research Dr. Charles A. Berry, UTMB partnered with the blossoming era of exploration by monitoring astronauts. In 1993, UTMB and the NASA Johnson Space Center created the joint Aerospace Medicine Residency Program, which used bed facilities at the Galveston branch to simulate weightlessness. Wherever there has been a question about how flight and space affect health, odds are UTMB has been involved.

The Department of Aerospace and Exploration Medicine will launch several new initiatives soon. One planned for 2027 is an Undersea and Hyperbaric Medicine Fellowship that will allow scientists to study the physiology of high-pressure flight.

“In the era of a growing global space economy, we are revisiting questions such as who is flying, what is their destination, what vehicle will get them there?” Shah added in the release. “The answers to these questions will drive what research is needed and how we train the next generation.”

Energy AI company opens first U.S. office at Houston's the Ion

new to hou

Building on its partnership with Houston-based oilfield services provider Halliburton, energy-sector AI company Shape Digital recently opened an office at The Ion. It’s the company’s first U.S. location.

Shape Digital’s workforce in Houston includes employees specializing in tech support, business development and client services. The company’s local hiring projections and headcount weren’t available. The new office will be located within Industrious at the Ion, according to Rice Alliance.

A key driver of the new Houston office: The company forecasts North America will account for more than 20 percent of its business in 2027.

“North America is a critical market for industrial innovation, and Houston sits at the center of companies driving that progress,” Caio Sene, vice president of client services at Shape Digital, said in a release. “Growing our presence here allows us to work alongside operators as they look for practical ways to turn existing operational data into clear recommendations for what to do next.”

Shape Digital, which also has offices in Singapore and Brazil, develops decision-making platforms for the oil and gas sector.

The Ion District office gives Shape Digital a presence close to Halliburton’s headquarters. In May, the two companies forged a partnership to combine Halliburton’s Digital Field Solverdecision-making system with Shape Digital’s AI portfolio.

Shape Digital layers AI software atop existing operations data rather than replacing legacy systems or adding new software.

The company’s suite of AI agents draws on more than 200 operations-monitoring algorithms, continually learning from company and industry data. The suite comprises four products: Shape Aura, Shape Lighthouse, Shape Lumen and Shape Reef.

Shape Digital says that by working with a customer’s existing operations data, it can deliver ROI in less than two months without any additional investment in equipment or infrastructure.

The company is a 2021 spinoff of Japan-based Modec. Modec builds, owns, and operates floating offshore oil and gas production facilities. Its Modec America subsidiary is based in Houston.
