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.

PATH EX

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

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.

Rice University launches new center to study roots of Alzheimer’s and Parkinson’s

neuro research

Rice University launched its new Amyloid Mechanism and Disease Center last month, which aims to uncover the molecular origins of Alzheimer’s, Parkinson’s and other amyloid-related diseases.

The center will bring together Rice faculty in chemistry, biophysics, cell biology and biochemistry to study how protein aggregates called amyloids form, spread and harm brain cells. It will serve as the neuroscience branch of the Rice Brain Institute, which was also recently established.

The team will work to ultimately increase its understanding of amyloid processes and will collaborate with the Texas Medical Center to turn lab discoveries into real progress for patients. It will hold its launch event on Jan. 21, 2026, and hopes to eventually be a launchpad for future external research funding.

The new hub will be led by Pernilla Wittung-Stafshed, a Rice biophysicist and the Charles W. Duncan Jr.-Welch Chair in Chemistry.

“To make a real difference, we have to go all the way and find a cure,” Wittung-Stafshede said in a news release. “At Rice, with the Amyloid Mechanism and Disease Center as a catalyst, we have the people and ideas to open new doors toward solutions.”

Wittung-Stafshede, who was recruited to Rice through a Cancer Prevention and Research Institute of Texas grant this summer, has led pioneering work on how metal-binding proteins impact neurodegenerative disorders, including Alzheimer’s and Parkinson’s diseases. Her most recent study, published in Advanced Science, suggests a new way of understanding how amyloids may harm cells and consume the brain’s energy molecule, ATP.

According to Alzheimer’s Disease International, neurodegenerative disease cases could reach around 78 million by 2030 and 139 million by 2050. Wittung-Stafshede’s father died of dementia several years ago.

“This is close to my heart,” Wittung-Stafshede added in the news release. “Neurodegenerative diseases such as dementia, Alzheimer’s and Parkinson’s are on the rise as people live longer, and age is the largest risk factor. It affects everyone.”

This Houston airport saw sharp passenger decline in 2025, study shows

Travel Talk

A new global airport travel study has revealed passenger traffic at Houston's William P. Hobby Airport (HOU) sharply decreased from 2024 to 2025.

The analysis from travel magazine LocalsInsider examined recently released data from the Bureau of Transportation Statistics (BTS), the U.S. International Trade Association, and a nationwide survey to determine the following American traveler habits: The most popular U.S. and international destinations, emerging hotspots, and destinations on the decline. The study covered passenger travel trends from January through July 2025.

In the report's ranking of the 40 U.S. airports with the sharpest declines in passenger traffic, HOU ranked 13th on the list.

About 4.26 million arrivals were reported at HOU from January through July 2024, compared to about 3.96 million during the same seven-month period in 2025. According to the data, that's a significant 7.1 percent drop in passenger traffic year-over-year, or a loss of 300,974 passengers.

"As travelers chase new hotspots, some destinations are seeing reduced passenger traffic whether due to rising costs, shifting airline schedules, or evolving traveler preferences, some destinations are seeing a decrease in visitors," the report's author wrote.

It appears most major Texas airports had drops in passenger traffic from 2024 to 2025. Dallas Love Field Airport (DAL) saw the worst in the state, with a dramatic 7.4 percent dip in arrivals. DAL also ranked 11th on the list of U.S. airports with the steepest declines in passenger traffic.

More than 5.13 million arrivals were reported at DAL from January through July 2024, compared to over 4.75 million during the same seven-month period in 2025.

This is how passenger traffic has fallen at other major Texas airports from 2024 to 2025:

Austin-Bergstrom International Airport (AUS):

  • 6,107,597 – Passenger arrivals from January to July 2024
  • 5,828,396 – Passenger arrivals from January to July 2025
  • -4.6 percent – Year-over-year passenger change
Dallas/Fort Worth International Airport (DFW):
  • 23,830,017 – Passenger arrivals from January to July 2024
  • 23,251,302 – Passenger arrivals from January to July 2025
  • -2.4 percent – Year-over-year passenger change

San Antonio International Airport (SAT):

  • 2,937,870 – Passenger arrivals from January to July 2024
  • 2,836,774 – Passenger arrivals from January to July 2025
  • -3.4 percent – Year-over-year passenger change
El Paso International Airport (ELP):
  • 1,094,431 – Passenger arrivals from January to July 2024
  • 1,076,845 – Passenger arrivals from January to July 2025
  • -1.6 percent – Year-over-year passenger change

NASA names new chief astronaut based in Houston

new hire

NASA has a new chief astronaut. Scott Tingle, stationed at the space agency’s Johnson Space Center in Houston, assumed the post Nov. 10.

Tingle succeeds NASA astronaut Joe Acaba, who had been chief astronaut since February 2023. Acaba now works on the staff of the Johnson Space Center’s director.

As chief astronaut, Tingle runs NASA’s Astronaut Office. His job includes developing astronauts’ flight crew operations and assigning crews for space missions, such as Artemis missions to the moon.

Tingle, a former captain in the Navy, was named a NASA astronaut candidate in 2009. He has logged over 4,500 flight hours in more than 50 aircraft.

Tingle was a flight engineer aboard the International Space Station, where he spent 168 days in orbit during two expeditions that launched in December 2017. Since returning to Earth, he has held various roles in the Astronaut Office, including mission support, technical leadership and crew readiness.

Before joining NASA, Tingle worked in El Segundo, California, on the technical staff of The Aerospace Corp., a nonprofit that supports U.S. space programs.

Tingle recalls expressing his desire to be an astronaut when he was 10 years old. It took him four tries to be accepted by NASA as an astronaut candidate.

“The first time I figured it was kind of too early. The second application, they sent out some feelers, and that was about it. Put in my third application, and got a couple of calls, but it didn’t quite happen,” Tingle said in an article published on the website of Purdue University, his alma mater.
