A team of Rice University engineers has developed an implantable probe over a hundred times smaller than the width of a hair that aims to help develop better treatments for spinal cord disease and injury.

Detailed in a recent study published in Cell Reports, the probe or sensor, known as spinalNET, is used to explore how neurons in the spinal cord process sensation and control movement, according to a statement from Rice. The research was supported by the National Institutes of Health, Rice, the California-based Salk Institute for Biological Studies, and the philanthropic Mary K. Chapman Foundation based in Oklahoma.

The soft and flexible sensor was used to record neuronal activity in freely moving mice with high resolution for multiple days. Historically, tracking this level of activity has been difficult for researchers because the spinal cord and its neurons move so much during normal activity, according to the team.

“We developed a tiny sensor, spinalNET, that records the electrical activity of spinal neurons as the subject performs normal activity without any restraint,” Yu Wu, a research scientist at Rice and lead author of the study said in a statement. “Being able to extract such knowledge is a first but important step to develop cures for millions of people suffering from spinal cord diseases.”

The team says that before now the spinal cord has been considered a "black box." But the device has already helped the team uncover new findings about the body's rhythmic motor patterns, which drive walking, breathing and chewing.

"Some (spinal neurons) are strongly correlated with leg movement, but surprisingly, a lot of neurons have no obvious correlation with movement,” Wu said in the statement. “This indicates that the spinal circuit controlling rhythmic movement is more complicated than we thought.”

The team said they hope to explore these findings further and aim to use the technology for additional medical purposes.

“In addition to scientific insight, we believe that as the technology evolves, it has great potential as a medical device for people with spinal cord neurological disorders and injury,” Lan Luan, an associate professor of electrical and computer engineering at Rice and a corresponding author on the study, added in the statement.

Rice researchers have developed several implantable, minimally invasive devices to address health and mental health issues.

In the spring, the university announced that the United States Department of Defense had awarded a four-year, $7.8 million grant to the Texas Heart Institute and a Rice team led by co-investigator Yaxin Wang to continue to break ground on a novel left ventricular assist device (LVAD) that could be an alternative to current devices that prevent heart transplantation.

That same month, the university shared news that Professor Jacob Robinson had published findings on minimally invasive bioelectronics for treating psychiatric conditions. The 9-millimeter device can deliver precise and programmable stimulation to the brain to help treat depression, obsessive-compulsive disorder and post-traumatic stress disorder.

Houston startup with unique vascular innovation enrolls subjects in new trial

medical device momentum

A Houston-based company has enrolled the initial subjects in a first-of-its-kind trial.

VenoStent was created to improve vascular surgery outcomes for patients undergoing arteriovenous fistula (AVF) creation surgery.

“When a vein is connected to an artery, as in AVF creation, the vein experiences a 10x increase in pressure and flow that is traumatizing to veins. Many fail to become usable for dialysis,” Geoffrey Lucks, VenoStent COO and co-founder, says in a news release.

Enter VenoStent’s SelfWrap Bioabsorbable Perivascular Wrap, better known as simply SelfWrap. In May 2023, SelfWrap gained FDA approval to begin its US IDE Study, SAVE-FistulaS: The SelfWrap-Assisted ArterioVEnous Fistula Study.

Roughly half a million Americans need hemodialysis just to survive another day. Nearly all of those patients require a vascular access creation surgery, but the procedure has a 50-percent failure rate in its first year. VenoStent and SelfWrap are aimed at improving those odds. It works by using the body’s own healing mechanism.

SelfWrap is a flexible, bioabsorbable vascular wrap that helps to recreate the arterial environment in veins. Over time, the body replaces the SelfWrap with venous tissue.

The company has begun to enroll patients for what will eventually be a 200-subject study. Some of those people have radiocephalic fistulas, others have brachiocephalic ones. This is important, because it will likely prove that the technology works for most types of AVFs. The sites for this clinical trial are at the Surgical Specialists of Charlotte, P.A. in Charlotte, NC, and the Cardiothoracic and Vascular Surgeons in Austin.

“While it’s ambitious and sets a high bar for FDA Approval, we owe it to the chronic kidney disease (CKD) patient community to provide the highest level of clinical evidence,” Timothy Boire, CEO and cofounder, says in the release. “We’re confident based on years of preclinical and clinical data that we’ll demonstrate superiority to standard of care with this breakthrough technology.”

VenoStent recently completed a $16 million Series A, financed by Good Growth Capital and IAG Capital. This is the first-ever randomized controlled trial of a medical device designed to improve outcomes from arteriovenous fistula (AVF) creation surgery in the United States.

Rice University medical device spinout secures nearly $19M series A

fresh funding

A health tech startup based out of a newly formed accelerator program at Rice University has raised venture funding.

Motif Neurotech closed its series A round with an oversubscribed $18.75 million. The company, which develops minimally invasive bioelectronics for mental health treatment, was formed out of the Rice Biotech Launch Pad that launched last fall.

The round was led by Arboretum Ventures, with participation from new investors KdT Ventures, Satori Neuro, Dolby Family Ventures, re.Mind Capital and existing investors Divergent Capital, TMC Venture Fund, PsyMed Ventures, Empath Ventures and Capital Factory, according to a news release from Rice.

“Minimally invasive bioelectronics are the future of mental health treatment,” Jacob Robinson, CEO and founder of Motif Neurotech, says in the release. “Thirty percent of patients with depression don’t respond to two or more medications, and there is a significant need for additional treatment options that are effective and easily accessible."

The fresh funding will go toward developing the inaugural product, the DOT microstimulator, a wireless, battery-free device that can provide at-home therapy for treatment-resistant depression, or TRD, a major depressive disorder.

“This is a pivotal moment for the company as it closes its Series A in addition to the recent successful completion of the proof-of-concept first-in-human implant of the DOT stimulator device," Tom Shehab, managing partner of Arboretum Ventures, says in the release. "We believe Motif’s device will greatly improve the quality of life for patients who have been diagnosed with difficult to treat mental health disorders, including TRD."

Shehab, along with Amy Kruse, chief investment officer of Satori Neuro, will reportedly join Motif Neurotech's board of directors alongside Anthony Arnold, president and CEO of Sensydia Corporation, and Jacob Robinson, professor of electrical and computer engineering and bioengineering at Rice.

The Rice Biotech Launch Pad was established to take biotech innovations from concept to clinical trials in five years or less. It occupies 15,000 square feet of space on campus and is funded through federal grants and donations.

Houston innovator makes major headway on his portable stroke rehab device

research milestone

A University of Houston professor has taking a huge step in advancing his game-changing stroke recovery tech.

Jose Luis Contreras-Vidal, the director of the UH BRAIN Center, recently published his work on a noninvasive brain-machine in a summer issue of the journal Sensors. InnovationMap first reported on Contreras-Vidal's technology in 2022, when it was being tested.

Contreras-Vidal's device uses a wireless, mobile dry-electrode headset placed on the scalp to convert electroencephalography (EEG) recordings (or measurements of electrical activity in different parts of the brain) to interface with a closed-loop brain–computer (BCI) and communicate with exoskeleton devices. Together, the technology triggers robotic movement based on the wearer's brain activity.

The technology has potential to boost cortical plasticity after a stroke, which can improve motor skills recovery.

According to a statement from UH, a patent is pending on Contreras-Vidal's BCI algorithm and the self-positioning dry electrode bracket used on the scalp. The technology has also now been validated and tested at the University of Houston.

Contreras-Vidal says the technology makes stroke recovery easier for the user and even possible at home.

“Most commercial EEG-based BCI systems are tethered to immobile processing hardware or require complex programming or set-up, making them difficult to deploy outside of the clinic or laboratory without technical assistance or extensive training," he says in a statement. "A portable and wireless BCI system is highly preferred so it can be used outside lab in clinical and non-clinical mobile applications at home, work, or play.”

Additionally, the technology uses off-the-shelf components and is adjustable to fit about 90 percent of the population, according to UH.

"Current commercial EEG amplifiers and BCI headsets are prohibitively expensive, lack interoperability, or fail to provide a high signal quality or closed-loop operation, which are vital for BCI applications,” Contreras-Vidal adds.

The development of this technology was originally funded in part by an $813,999 grant from the National Science Foundation’s Division of Translational Impacts. UH reports that about 795,000 people in the United States suffer from a stroke annually.

Other leaders in Houston’s medical industry have tapped into innovative ways to treat and rehabilitate stroke patients in recent years. Baylor St. Luke's Hospital began using AI to reduce the time it takes to treat patients who've suffered from a stroke in 2021.

Houston health tech startup secures $16M series A, prepares for first U.S. clinical trials

money moves

Fueled by fresh funding in the bank, a medical device startup has announced upcoming trials.

VenoStent, Inc., a company developing an innovative tool to improve outcomes for hemodialysis patients, has closed $16 million in a series A round of financing. Two Charleston, South Carolina-based firms — Good Growth Capital and IAG Capital Partners — led the round.

The company also announced it received Investigational Device Exemption from the FDA for its United States clinical trial, SAVE-FistulaS.

“Our mission at VenoStent is to improve the quality and length of life of dialysis patients. On the heels of our very promising results in several preclinical studies and a 20-patient feasibility study that led to our Breakthrough Designation last year, this recent IDE approval is perhaps our biggest milestone to date," Tim Boire, CEO of VenoStent, says in a news release. "We now enter an exciting new epoch in our company’s development that we believe will ultimately result in FDA Approval and vastly improve the quality and length of life for patients."

VenoStent's series A will fund the trial, expand manufacturing capabilities, and more. The company is targeting the more than 800,000 people in the U.S. with end-stage renal disease. Currently, more than half of the surgeries performed to initiate hemodialysis fail within a year. VenoStent's novel therapeutic medical device is a bioabsorbable wrap that reduces vein collapse by providing mechanical support and promoting outward vein growth.

“This trial is designed to provide the highest level of clinical evidence. We’re excited to be in this position to treat the first patients in the United States with this technology, and demonstrate the safety and efficacy of our device,” continues Boire in the release.

Per the release, the company is aiming for FDA Approval and be the first-to-market device to improve hemodialysis access surgery.

“We’re extremely pleased to be partnering with VenoStent on this critical mission. This company and technology are poised for commercial success to address a critical, unmet need,” says Bob Crutchfield, operating partner at Good Growth Capital, in the release.

The TMC Venture Fund also contributed to the series A investment round, along with SNR, Baylor Angel Network / Affinity Fund, Creative Ventures, Cowtown Angels, Alumni Ventures, and other notable angel investors. Past investors in VenoStent include KidneyX, National Science Foundation, National Institute of Health, Y Combinator, Health Wildcatters, and the Texas Halo Fund.

“VenoStent’s data and traction to date is impressive and gives us a lot of confidence in their continued success. We look forward to helping them get this Breakthrough product to market and help patients that are in dire need of this innovative technology,” says Joel Whitley, partner at IAG Capital Partners, in the release.

Texas earns 22nd 'best state for business' title as GDP hits $2.9T

booming economy

The Texas business sector recently received a double dose of good news.

For the 22nd consecutive year, Chief Executive magazine named Texas the best state for business. In tandem with that achievement, preliminary new estimates from the U.S. Bureau of Economic Analysis show the size of Texas’ economy jumped to $2.9 trillion in 2025, up by a nation-leading growth rate of 2.5 percent compared with the previous year.

Speaking about the Chief Executive honor, Gov. Greg Abbott says Texas benefits from pro-growth policies, a strong workforce, strategic investments in education, training for high-demand skills and the presence of critical infrastructure.

“Texas is where businesses innovate and where opportunity abounds. … We will continue to move at the speed of business as we build a more prosperous Texas for generations to come,” the governor says.

An annual Chief Executive survey of CEOs, presidents and business owners determines which state is the best for business. Texas has landed at No. 1 every year since Chief Executive launched the ranking.

“Truly, this is an incredible run that Texas has going,” says Christopher Chalk, publisher of Chief Executive. “CEOs are a tough group to please, and yet year after year Texas continues to earn the top spot—no small feat.”

It’s also no small feat for a state to notch annual gains in its gross domestic product (GDP), a measurement of economic power based on the value of goods and services produced each year.

With an estimated GDP of $2.9 trillion last year, Texas maintains its position as the eighth-largest global economy compared with the nations of the world, based on preliminary estimates from the International Monetary Fund.

In reference to Texas’ GDP growth, Abbott says the Lone Star State is “the premier destination for job creators from across the country and world. We will keep attracting world-class investment, create jobs, and expand opportunity for Texans for generations to come.”
