Earlier this month, 16 medical device companies wrapped up their time at the Texas Medical Center's accelerator program and pitched their companies to fellow health professionals, guests, and more. While each made important connections in the local ecosystem during the program, a quarter of the entrepreneurs had roots in Houston already.

Four of the 16 TMCx09 companies that are headquartered in Houston. They have built solutions within sepsis, surgery, and transplant spaces in health care. Here's a little more about the homegrown companies that pitched at the event.

The standard practice for acute heart failure patients is very invasive, says William Altman, CEO of CorInnova.

"The problem with existing devices is that they have invasive blood contact," Altman says. "Problem with that is blood contact is bad. It can cause up to 15 percent rate of stroke, which could kill you, and after five to seven days it provides 10 percent rate of blood destruction and has a 47 percent rate of kidney disfunction."

CorInnova's technology features a device that can be easily inserted through a 1-inch incision, and then be used for increase blood pumping by 50 percent.

"Surgeons tell us this is less invasive than minimally invasive aortic valve replacement, which is a widely done surgery, so this promises widespread adoption for our technology as we get it approved," Altman says.

The human prototype is expected to be ready in two years, with the next year being focused on animal studies. CorInnova is raising $12 million to accomplish its goals.

An estimated 10 to 15 percent of the United States population will get a gallstone in their lifetime. Should one of those stones cause trouble or blockages, the only solution is to remove the gallbladder completely through surgery. However, Matthew Nojoomi, CEO and co-founder of Ictero Medical, has another idea.

Ictero Medical has created a minimally invasive treatment that uses cryoablation to defunctionize the gallbladder without having to remove it.

"The CholeSafe System not only treats the source of the disease, but it leverages existing clinical workflows that doctors use to access the gallbladder," says Nojoomi, adding that the process only uses mild station and pain control.

The company expects to get to humans in the next two years, and has launched a financing round.

Currently, sepsis is hard to identify in patience. Even if a patient is in a hospital, and that hospital knows the patient has sepsis, the individual still has a 38 percent chance of dying, says Sinead Miller, CEO of PATH EX.

"Right now the problems associated with sepsis are very clear," she says. "It's the leading cause of death in our ICUs, and it's also associated with the highest hospital cost and readmission rates."

PATH EX's technology allows medical professionals to better diagnose and treat sepsis. The PATH EX therapeutic device can be hooked up to a patient and flow his or her blood through the machine to capture bacteria, clean and recirculate the blood, and faster diagnose what sort of bacteria the patient has attracted. The device technology is similar to hemo hemodialysis, Miller explains.

The Houston company, which recently won big at the Ignite Healthcare Network's Fire Pitch Competition, was named an honoree within the Johnson and Johnson Breakthrough Medical Technologies Quickfire Challenge.

The company was recently received clearance from the Food and Drug Administration as a breakthrough device technology. PATH EX closed its $615,000 seed round — with plans for a series A next year — and has received $1 million in SBIR grant funding. The company was founded two years ago, and relocated to call Houston HQ this year.

Volumetric is banking on their technology being among the inventions that will lead the medical industry into the future. The human tissue-printing technology company has created the 3D printer and the "ink" that can create whole organs for transplant.

"We can create complicated vascular architectures inside of soft water-based gels, in this case, mimicking the structure and function of human lung tissue," says Jordan Miller, CEO. "We can oxygenate red blood cells."

The company is commercializing its technology and has three streams of revenue, which as generated almost $1 million in revenue in Volumetric's second year. The company is also in the process of closing its seed round of fundraising.

Earlier this year, the startup, which works out of Rice University, was featured on the cover of Science magazine.

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”

Rice University to lead AI conferences in Paris this spring and summer

where to be

Houston’s own Rice University will host a series of conferences on artificial intelligence in Paris, France, starting this month. The series will tackle the impact and possibilities of AI in fields like econometrics and online privacy security.

“Artificial intelligence is transforming the global economy and raising profound questions about how technology intersects with society,” Caroline Levander, Rice’s vice president for global strategy, said in a news release. “By convening scholars from multiple disciplines and countries in Paris, Rice is helping shape the international conversation about how AI should be developed, governed and used.”

The four conferences in Paris aim for a multi-disciplinary approach that tackles aspects of AI from diverging angles. The conferences come as part of Rice’s increased partnership with French researchers at the Université Paris Sciences & Lettres. The two institutions have formed a binary star system of academic sharing and support.

“Paris has quickly become one of the most important global hubs for artificial intelligence research, entrepreneurship and policy,” Levander said. “For Rice, having a presence in the city allows our scholars to engage directly with that ecosystem while building collaborations that connect Europe and the United States around the future of AI.”

The conferences will be held at the Rice Global Paris Center. Topics scheduled are:

Emerging Topics in Operations Management: Platforms, Blockchains and AI

April 27-29

This conference will focus on how companies like Uber, Airbnb, Spotify, and DoorDash can use blockchain ledgers to deliver goods and services more transparently. It will also look at tokenized incentives, presumably forms of cryptocurrency and non-fungible tokens in the app space.

Econometrics and AI

May 5-7

This conference will explore how AI can be used in various economic statistical models and practices.

Human Flourishing in the Age of AI

June 3-5

This conference will be a collaboration between engineers and philosophers about the ethics and impact of AI on the lives of its users.

On the Crossroads of AI and Society: Incentives, Privacy and Fairness

July 15-16

This conference will consider how to stakeholders can ensure AI’s actions most benefit people, particularly in the fields of healthcare education, energy and public policy.

Houston claims 19% of Texas’ new live-work-play growth

by the numbers

In Texas, Houston is a big player in the live-work-play real estate movement.

A new 21-city analysis from coworking marketplace CoworkingCafe shows the Houston area added five live-work-play projects—mixed-use developments with residential, office and recreational components—over the past decade.

From 2016 to 2025, Houston accounted for 19 percent of Texas’ new live-work-play inventory, the analysis shows. Among the new local developments were Arrive Upper Kirby, St. Andrie, and The Laura:

  • Arrive Upper Kirby, which was sold in 2021 for $182 million, offers more than 61,000 square feet of retail and restaurant space adjacent to apartments and offices. The 13-story, 265,000-square-foot project was completed in 2017.
  • St. Andrie, a 32-acre, mixed-use community, was completed in 2019. The apartment-anchored development includes an H-E-B grocery store and 37,000 square feet of office space.
  • The Laura, spanning 110,000 square feet, was completed in 2023. Among the apartment complex’s amenities is a coworking space.

According to Northspyre, a software provider for real estate developers, live-work-play projects enable people to meet their needs, such as housing, workplaces, stores, restaurants, and recreation facilities, in a single place.

A total of 542 live-work-play developments opened between 2016 and 2025 in the 21 cities, with another 69 in the pipeline for 2026, CoworkingCafe says. Among major markets, New York City made up the largest share (119) of new live-work-play developments from 2016 to 2025.

The Houston area’s five projects were built in 2018, 2019, 2020, 2024, and 2025, CoworkingCafe data indicates, with another project scheduled for completion next year. The Greater Houston Partnership recently highlighted four mixed-use projects taking shape in the region, but only one of them is scheduled to be finished in 2027. It can take two to five years or more to complete a mixed-use development.

Of the five Houston developments finished in the past decade, 56 percent of the space went toward multifamily units, 29 percent toward offices, and 16 percent toward retail, CoworkingCafe says.

As noted by the Houston-Galveston Area Council, economic development in the 21st century “is about cultivating quality live-work-play environments that attract, retain, and grow a diverse and skilled population. Employers and businesses are increasingly choosing to make long-term investments in places that connect and engage people to strengthen economic competitiveness and promote innovation.”

With eight completed projects, Austin led construction of live-work-play developments in Texas from 2016 to 2025, according to CoworkingCafe. Dallas, which welcomed five live-work-play developments during that period, tied with Houston. San Antonio data wasn’t available.
