Undergraduate students from Rice University were awarded the top prize in a health innovation challenge.

Design by Biomedical Undergraduate Teams (DEBUT) Challenge, which is organized by the National Institutes of Health (NIH) and the non-profit organization VentureWell, selected medical device team UroFlo as its winner, claiming the $20,000 prize. The technology, a continuous bladder irrigation system, was recognized for its potential to revolutionize post-operative care and improve patient outcomes.

The winning team from Rice consists of 2024 bioengineering graduates Anushka Agrawal, Sahana Prasanna, Robert Heeter, Archit Chabbi, Kevin Li, and Richard Chan. The UroFlo system provides care to patients after surgery and reduces the burden on health care professionals by implementing state-of-the-art sensors and machine learning algorithms with a touchscreen user interface. This helps with data collection, processing and visualization. UroFlo promises to enhance the management of urinary tract infections (UTIs) and help prevent blood clots.

“We have learned so much from this process and we are really proud of what we have accomplished,” says Chabbi in a news release. “It’s truly rewarding to know that our work can impact patients’ experience and help improve quality of care. Over the many hours we spent working in the Oshman Engineering Design Kitchen (OEDK) at Rice, we’ve not only developed an amazing set of skills, but have also forged really strong connections with one-another and the nearby medical community at the Texas Medical Center.”

The award will be presented on Oct. 25 in Baltimore during the annual Biomedical Engineering Society (BMES) conference.

UroFlo was also with first place in the Johns Hopkins Healthcare Design Competition in the Post-Surgical Infection Management category; first place in the American Society for Artificial Internal Organs Student Design Competition; “Best Medical Device Technology Award” in the 2024 Huff Engineering Design Showcase and competition held by the OEDK; “Outstanding Bioengineering Design Project,” Rice Department of Bioengineering; “Best Presentation” in the Texas Children’s Hospital Surgical Research Day; finalist and “Best Engineering Project” in Rice’s 2024 Shapiro Research Showcases; and semi-finalist in the H. Albert Napier Rice Launch Challenge. UroFlo will continue after Rice, as the project will be developed further.

“We are all very passionate about biomedical engineering, and dedicated and committed to making a difference” Chan said in a news release. “We actually decided to continue to develop UroFlo after our graduation from Rice a few months ago with the hope of improving our innovative solution for urological care.”

In other news, Rice University’s Naomi Halas won $7.5 million over five years from the United States Department of Defense (DOD) Air Force Office of Scientific Research (AFOSR) with her project proposal Multidisciplinary University Research Initiative (MURI) for her project titled “Combining Nonequilibrium Chemistries with Atomic Precision,” which competed in the category “plasmon-controlled single-atom catalysis.”

“Combining Nonequilibrium Chemistries with Atomic Precision” addressed the need for more energy-efficient and less protocol-intensive chemical processes that involve using light to drive chemical reactions and single-atom “reactors” to catalyze chemical reactions that are nearly 100 percent specific in terms of reaction products.

Plasmons work when they make metal nanoparticles act like antennas, and certain designed reactor sites on their surfaces can then carry out chemical reactions at a fraction of the “energy expenditure of conventional industrial catalysts” according to a news release.

Rice University and Baylor College of Medicine have also received $2.8 million in funding from the National Heart, Lung, and Blood Institute (NHLBI) for their research on reducing inflammation and lung damage in acute respiratory distress syndrome (ARDS) patients.

“Cell Based Immunomodulation to Suppress Lung Inflammation and Promote Repair,” will be co-led byRice’s Omid Veiseh, a professor of bioengineering and faculty director of the Rice Biotech Launch Pad, and professor of surgery at Baylor Ravi Kiran Ghanta. They will develop a new translational cell therapy platform “ to allow a better local administration of cytokines to the lungs in order to suppress inflammation and potentially prevent lung damage in ARDS patients” according to a news release.

A ventilator that was designed by a team at Rice University has received Emergency Use Authorization from the U.S. Food and Drug Administration amid the COVID-19 pandemic.

The ApolloBVM was worked on March by students at Rice's Brown School of Engineering's Oshman Engineering Design Kitchen, or OEDK. The open-source plans were shared online so that those in need could have access to the life-saving technology. Since its upload, the ApolloBVM design has been downloaded by almost 3,000 registered participants in 115 countries.

"The COVID-19 pandemic pushed staff, students and clinical partners to complete a novel design for the ApolloBVM in the weeks following the initial local cases," says Maria Oden, a teaching professor of bioengineering at Rice and director of the OEDK, in the press release. "We are thrilled that the device has received FDA Emergency Use Authorization."

While development began in 2018 with a Houston emergency physician, Rohith Malya, Houston manufacturer Stewart & Stevenson Healthcare Technologies LLC, a subsidiary of Kirby Corporation that licensed ApolloBVM in April, has worked with the team to further manufacture the device into what it is today.

The Rice team worked out of OEDK throughout the spring and Stewart & Stevenson joined to support the effort along with manufacturing plants in Oklahoma City and Houston.

"The FDA authorization represents an important milestone achievement for the Apollo ABVM program," says Joe Reniers, president of Kirby Distribution and Services, in the release. "We can now commence manufacturing and distribution of this low-cost device to the front lines, providing health care professionals with a sturdy and portable ventilation device for patients during the COVID-19 pandemic."

Reniers continues, "It is a testimony to the flexibility of our people and our manufacturing facilities that we are able to readily utilize operations to support COVID-19 related need."

The device's name was selected as a tribute to Rice's history with NASA and President John F. Kennedy's now-famous speech kicking off the nation's efforts to go to the moon. It's meaningful to Matthew Wettergreen, one of the members of the design team.

"When a crisis hits, we use our skills to contribute solutions," Wettergreen previously told CultureMap. "If you can help, you should, and I'm proud that we're responding to the call."

Rice University students and staff team up with Canadian company to make low-cost ventilators

hi, tech

As the COVID-19 case numbers continue to grow, hospitals around the world are either experiencing or expecting a shortage of ventilation units. In Houston, a team of students and staff at Rice University have designed a solution.

Along with Canadian global health design firm, Metric Technologies, the Rice team has developed an automated bag valve mask ventilator that can be crafted for less than $300. Moreover, the team expects to share the designs so that these low-cost machines can be produced everywhere.

The project is being called Take a Breatherand was inspired by an early prototype that a group of engineering seniors developed in 2019 at Rice's Brown School of Engineering'sOshman Engineering Design Kitchen, or OEDK. The idea was to take a bag valve mask, which medical professionals use manually by squeezing with their hands, and create a device that can instead compress the bag automatically.

The parts of the device are largely created via 3D printing and laser cut, according to a press release from Rice, and only took around a week to prototype. While the original project was created to help emergency medicine professionals using a manual ventilator, the device is very relevant in the current coronavirus crisis.

"The immediate goal is a device that works well enough to keep noncritical COVID-19 patients stable and frees up larger ventilators for more critical patients," says Amy Kavalewitz, executive director of the OEDK, in the release.

As principal at Metric Technologies, Dr. Rohith Malya, who is assistant professor of emergency medicine at Baylor College of Medicine and an adjunct assistant professor of bioengineering at Rice, saw the growing need for for automated ventilator masks in emergency medicine.

"This is a clinician-informed end-to-end design that repurposes the existing BVM global inventory toward widespread and safe access to mechanical ventilation," Malya says in the release.

According to Malya, more than 100 million bag valve masks are produced annually. The designed device, which can work with these bags, has been named the ApolloBVM — a nod to when President John F. Kennedy announced from the Rice campus that it was his mission to get America to the moon.

"This project appeals to our ingenuity, it's a Rice-based project and it's for all of humanity," he says in the release. "And we're on an urgent timescale. We decided to throw it all on the table and see how far we go."

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
