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.

Houston's new state-of-the-art academy FLAMA breaks ground at historic site

Groundbreaking Education

Houston’s newest school for arts and music broke ground in October in the city’s historic East End. The Frank Liu Jr. Academy for Music and Arts (FLAMA), a tuition-free charter school, will welcome students in pre-K through 8th grade next August.

Members of the Liu family, the school’s founding board members, elected officials, and East End community partners gathered at Buffalo Bayou Partnership’s historic Turkey Bend development for the official groundbreaking ceremony on October 8, which kicked off with a performance by the Kinder High School for the Performing and Visual Arts’ Mariachi group.

The new school is on a portion of the former Folgers Coffee Plant, located at 235 N. Norwood St. OMA, an international architectural firm known for its approach to urbanism, cultural projects, and adaptive reuse, is transforming the 1930s plant into a state-of-the-art educational facility.

“We’re excited to celebrate this milestone for FLAMA and look forward to seeing the transformation of the historic Folgers plant into a new home for music and arts education,” said Jason Long, one of the firm’s partners. “Like fine-tuning an instrument, our design recalibrates the existing industrial structure into an open, connected, and expressive environment for learning. FLAMA will be a new learning environment that builds on the character of the existing building while giving it new life for the community.”

Unfolding across three stories, the school draws inspiration from Montessori education principles, which prioritize openness, independence, and collective learning through shared “neighborhoods.”

It all begins when students, families and guests enter through a private courtyard. The welcoming space will change the building’s original industrial facade into a brightly colored, kid-friendly spot, complete with yellow and green blocks spelling out the school’s name. The original windows will be restored to preserve the building’s historic character and upgraded to meet contemporary energy standards. Similarly, all of the school’s classrooms are located around the building’s perimeter, providing an abundance of natural light.

Inside, FLAMA’s three stories are divided so that younger students will find their classrooms at the school’s base, and they will move upward through the school as they progress through grade levels. The ground level has a common area for younger kids that could host drum circles, movement classes, or “breakout play.”

Children in first and second grade have their own larger open space, with an eye-catching staircase, that's inspired by the curve of a French horn. The space lends itself to everything from small gatherings to performances by the school’s early musicians.

As students progress through third grade and up, they’ll find FLAMA’s upper floors created to meet their growing artistic and intellectual needs. One example is the open library, a shared spot for students in third through fifth grades. It has flexible furniture that can transform the space into a place for group study and project work, as well as one that can host after-school activities. Directly above this library is a second common room for middle schoolers where students in sixth, seventh, and eighth grades can study.

These two libraries are connected by an F-shaped floor opening that references both the F-hole of a string instrument and the forte symbol. Musicians know this curly f as a note indicating them to play a passage with strength. That could easily be a metaphor for the school itself, which will combine high-quality education with rigorous academics. This visual cue emphasizes FLAMA’s desire for music and art instruction to amplify learning across reading, writing, math, and science.

“This will be a place where children can discover their talents, families can find opportunities close to home, and music and art can open the doors to a stronger education,” said Congresswoman Sylvia Garcia, who attended the groundbreaking. “I know how much it matters when someone brings opportunity within the reach of a child.”

Dr. R. Scott Allen, FLAMA’s founding superintendent and former principal of Kinder HSPVA, spoke about the school’s vision to pair a rigorous, engaging academic opportunity with deep immersion in music and visual arts.

Congressman Christian Menefee, State Senator Carol Alvarado, and Houston City Councilmember Mario Castillo also delivered remarks at the ceremony, speaking about the school’s power to not only transform Houston’s Second, Third, and Fifth Ward communities, but also bring incredible education opportunities to students. Former Mayor Annise Parker, former State Board of Education Member Staci Childs, State Representative Christina Morales, and Houston City Councilmembers Joaquin Martinez and Sallie Alcorn also attended the event.

“In this city, known for our undeniable contributions to music and arts, the gap has never been ability or talent; it has always been opportunity, and opportunity can be built,” said Kirby Liu, who spoke at the groundbreaking, memorializing his late brother’s vision of arts education for the youngest Houstonians. “When it comes to opportunity being foreclosed on our children, we will try like hell to bust those damned doors down.”

The Frank Liu Jr. Foundation has pledged $20 million in financial support during FLAMA’s first years of operation. Applications are now open for kindergarten and first grade for the 2027-2028 school year.

New manufacturing facility breaks ground at NASA’s Johnson Space Center

making space

HITT Contracting has broken ground on NASA’s Applied Spaceflight Fabrication Facility (ASFF) at Johnson Space Center, the Washington, D.C.-based construction firm announced late last month.

The project, known as Building 70, will house a high-bay machine shop to support component production for future NASA space missions, according to HITT. The 37,625-square-foot building is the first part of a larger goal to create an engineering complex that unites assembly space, lab capabilities and manufacturing at JSC. It will consolidate machining equipment and operations that are currently spread across multiple campus buildings into one location.

The project broke ground in October at JSC’s Historic District. The Houston Business Journal reports construction is expected to wrap in August of 2028.

“This project will modernize facilities that support America’s space missions,” PJ Ross, chief financial officer at HITT, said in a LinkedIn post. “Proud of our team and partners as we begin construction that will advance aerospace testing and innovation.”

HITT Contracting is one of seven companies awarded infrastructure contracts by NASA earlier this year for work at JSC. According to NASA, the construction contracts “[support] up to $300 million in upgrades to mission‑support facilities, utilities, and equipment across the NASA Johnson campus.”

Construction Drive reports that HITT will also renovate Building 13 South on the JSC campus as part of the $300 million initiative.

“Building for precision manufacturing starts with understanding how the space needs to perform,” Todd Hudson, vice president at HITT Contracting, added in the release. “Our team brings the technical expertise and collaborative approach to deliver a facility that meets the Johnson Space Center’s needs today and supports the next generation of spaceflight innovation. We’re proud to continue our partnership with NASA.”

NASA also recently announced awards as part of its expanded Moon Base exploration, science and infrastructure capabilities. Houston-based Intuitive Machines and seven other spacetech companies, including SpaceX, Blue Origin and Firefly Aerospace, were selected to receive funding.

The awards are part of the next phase of NASA’s CLPS (Commercial Lunar Payload Services) initiative, which will grant the companies a combined total of up to $10 billion over 10 years.

Intuitive Machines and Webster-based MEI Technologies were also awarded contracts this past summer from NASA to develop robots for exploring the surface of Mars. Read more here.
