Houston-based Spark Biomedical has created a revolutionary wearable device that provides unprecedented levels of opioid withdrawal relief.

The device known as the Sparrow Therapy System is worn over the ear for five to seven days and sends mild electrical signals to trigger cranial nerves that sit near the skin's surface.

Once activated, the nerves release endorphins that the body has stopped producing on its own during opioid use. The endorphins satisfy the opioid receptors and in turn reduce or prevent the intense symptoms that often come along with opioid withdrawal. According to Spark BioMed CEO Daniel Powell, the technology also helps patients better control their "flight or fight mechanisms," allowing them to make clearer, more logical decisions as they come off of the drug.

"If you ask 100 people who've gone through opioid withdrawal, I would bet 99 of them will tell you they thought they were going to die," Powell says. "Giving them the ability to manage that is huge. It's the first step towards addiction recovery. It's not solving the addiction, but it is an absolute barrier to move forward."

The product was approved by the FDA in January of 2020, after clinical trials showed that the Sparrow could meaningfully reduce withdrawal symptoms in the first hour of use. According to Powell, roughly a third of patients in the trial were completely out of withdrawal and patients' Clinical Opioid Withdrawal Scales scores reduced by more than 53 percent across the board.

Spark, which won Venture Houston's inaugural pitch competition earlier this year, partnered with Houston-based Velentium (which also happened to grow 93 percent last year after partnering with General Motors on Project V) to bring the product from concept to commercial physician prescribed product. "We needed a more sophisticated design house to help us finish it," Powell says.

The up-and-comers were connected through one of Spark's investors. Powell, in a previous career, had also sold a neurostimulator that Velentium CTO Randy Armstrong had invented.

"You're seeing more and more Houston centric medical innovation than we've ever seen before," says Velentium CEO Dan Purvis. "And the cool thing about that is there ends up being a camaraderie amongst entrepreneurs, medical researchers and scientists."

And though the release of Sparrow marks a huge milestone, neither Spark of Velentium are stopping there. Moving forward, Spark aims to conduct a massive study on how a similar technology, dubbed the Roo, can aid infants born to opioid-dependent mothers wean from the drug.

The company also aims to create a next generation Sparrow with the help of Velentium, and will look at long-term uses of the product. Powell says that Spark will look to determine if the product can prevent relapses and help to cure addiction when worn daily or regularly.

"Our big, crazy, ambitious goal is can we actually help people recover from addiction," Powell says. "We're really not addressing psychology, that's going to be in cognitive behavioral therapy. But if we can remove the neurological results of drug use, we think we can make at least start to stack the deck in the favor of the patient versus having the deck stacked completely against them all the time."

Baylor College of Medicine names Minnesota med school dean as new president, CEO ​

new leader

Dr. Jakub Tolar, dean of the University of Minnesota Medical School, is taking over as president, CEO and executive dean of Houston’s Baylor College of Medicine on July 1.

Tolar—who’s also vice president for clinical affairs at the University of Minnesota and a university professor—will succeed Dr. Paul Klotman as head of BCM. Klotman is retiring June 30 after leading Texas’ top-ranked medical school since 2010.

In tandem with medical facilities such as Baylor St. Luke’s Medical Center and Texas Children’s Hospital, Baylor trains nearly half of the doctors who work at Texas Medical Center. In addition, Baylor is home to the Dan L Duncan Comprehensive Cancer Center and the Texas Heart Institute.

The hunt for a new leader at Baylor yielded 179 candidates. The medical school’s search firm interviewed 44 candidates, and the pool was narrowed to 10 contenders who were interviewed by the Board of Trustees’ search committee. The full board then interviewed the four finalists, including Tolar.

Greg Brenneman, chair of Baylor’s board and the search committee, says Tolar is “highly accomplished” in the core elements of the medical school’s mission: research, patient care, education and community service.

“Baylor is phenomenal. Baylor is a superpower in academic medicine,” Tolar, a native of the Czech Republic, says in a YouTube video filmed at the medical school. “And everything comes together here because science saves lives. That is the superpower.”

Tolar’s medical specialties include pediatric blood and bone marrow transplants. His research, which he’ll continue at Baylor, focuses on developing cellular therapies for rare genetic disorders. In the research arena, he’s known for his care of patients with recessive dystrophic epidermolysis bullosa, a severe genetic skin disorder.

In a news release, Tolar praises Baylor’s “achievements and foundation,” as well as the school’s potential to advance medicine and health care in “new and impactful ways.”

The Baylor College of Medicine employs more than 9,300 full-time faculty and staff. For the 2025-26 academic year, nearly 1,800 students are enrolled in the School of Medicine, Graduate School of Biomedical Sciences and School of Health Professions. Its M.D. program operates campuses in Houston and Temple.

In the fiscal year that ended June 30, 2024, Baylor recorded $2.72 billion in operating revenue and $2.76 billion in operating expenses.

The college was founded in 1900 in Dallas and relocated to Houston in 1943. It was affiliated with Baylor University in Waco from 1903 to 1969.

​Planned UT Austin med center, anchored by MD Anderson, gets $100M gift​

med funding

The University of Texas at Austin’s planned multibillion-dollar medical center, which will include a hospital run by Houston’s University of Texas MD Anderson Cancer Center, just received a $100 million boost from a billionaire husband-and-wife duo.

Tench Coxe, a former venture capitalist who’s a major shareholder in chipmaking giant Nvidia, and Simone Coxe, co-founder and former CEO of the Blanc & Otus PR firm, contributed the $100 million—one of the largest gifts in UT history. The Coxes live in Austin.

“Great medical care changes lives,” says Simone Coxe, “and we want more people to have access to it.”

The University of Texas System announced the medical center project in 2023 and cited an estimated price tag of $2.5 billion. UT initially said the medical center would be built on the site of the Frank Erwin Center, a sports and entertainment venue on the UT Austin campus that was demolished in 2024. The 20-acre site, north of downtown and the state Capitol, is near Dell Seton Medical Center, UT Dell Medical School and UT Health Austin.

Now, UT officials are considering a bigger, still-unidentified site near the Domain mixed-use district in North Austin, although they haven’t ruled out the Erwin Center site. The Domain development is near St. David’s North Medical Center.

As originally planned, the medical center would house a cancer center built and operated by MD Anderson and a specialty hospital built and operated by UT Austin. Construction on the two hospitals is scheduled to start this year and be completed in 2030. According to a 2025 bid notice for contractors, each hospital is expected to encompass about 1.5 million square feet, meaning the medical center would span about 3 million square feet.

Features of the MD Anderson hospital will include:

  • Inpatient care
  • Outpatient clinics
  • Surgery suites
  • Radiation, chemotherapy, cell, and proton treatments
  • Diagnostic imaging
  • Clinical drug trials

UT says the new medical center will fuse the university’s academic and research capabilities with the medical and research capabilities of MD Anderson and Dell Medical School.

UT officials say priorities for spending the Coxes’ gift include:

  • Recruiting world-class medical professionals and scientists
  • Supporting construction
  • Investing in technology
  • Expanding community programs that promote healthy living and access to care

Tench says the opportunity to contribute to building an institution from the ground up helped prompt the donation. He and others say that thanks to MD Anderson’s participation, the medical center will bring world-renowned cancer care to the Austin area.

“We have a close friend who had to travel to Houston for care she should have been able to get here at home. … Supporting the vision for the UT medical center is exactly the opportunity Austin needed,” he says.

The rate of patients who leave the Austin area to seek care for serious medical issues runs as high as 25 percent, according to UT.
