It's hard to understate the impact Dr. William Cohn has had on cardiovascular health as a surgeon at the Texas Heart Institute or on health care innovation as the director of the Center for Device Innovation at the Texas Medical Center. However, his role as chief medical officer of BiVACOR might be his most significant contribution to health care yet.

The company's Total Artificial Heart is unlike any cardiovascular device that's existed, Cohn explains on the Houston Innovators Podcast. While most devices are used temporarily for patients awaiting a heart transplant, BiVACOR's TAH has the potential to be a permanent solution for the 200,000 patients who die of heart failure annually. Last year, only around 4,000 patients were able to receive heart transplants.

"Artificial hearts historically have had bladders that ejected and filled 144,000 times a day. They work great for temporary support, but no one is suggesting they are permanent devices," Cohn says on the show. Read more.

Promising Houston cancer research project wins $18M grant

fresh funding

The Biden-Harris administration is deploying $150 million as a part of its Cancer Moonshot initiative, and a research team led by Rice University is getting a slice of that pie.

AccessPath is a novel, affordable, slide-free pathology system that helps surgeons determine if they have completely removed tumors during surgery. Rebecca Richards-Kortum, a Rice bioengineering professor and director of the Rice360 Institute for Global Health Technologies, is the lead PI on the project that is receiving up to $18 million over five years from the Advanced Research Projects Agency for Health (ARPA-H).

“Because of its low cost, high speed, and automated analysis, we believe AccessPath can revolutionize real-time surgical guidance, greatly expanding the range of hospitals able to provide accurate intraoperative tumor margin assessment and improving outcomes for all cancer surgery patients,” Richards-Kortum says in a news release.

The project is focused on two types of cancer, breast and head and neck cancer, and Ashok Veeraraghavan, chair of Rice’s Department of Electrical and Computer Engineering and a professor of electrical and computer engineering and computer science, is a co-PI and Tomasz Tkaczyk, a professor of bioengineering and electrical and computer engineering at Rice, is also a collaborator on the project.

AccessPath is addressing the challenge surgeons face of identifying the margin where tumor tissue ends and health tissue begins when removing tumors. The project not only hopes to provide a more exact solution but do so in an affordable way.

“Precise margin assessment is key to the oncologic success of any cancer operation,” adds Dr. Ana Paula Refinetti, an associate professor in the Department of Breast Surgical Oncology at The University of Texas MD Anderson Cancer Center and one of the lead surgeons PIs on the project. “The development of a new low-cost technology that enables immediate margin assessment could transform the landscape of surgical oncology — particularly in low-resource settings, reducing the number of repeat interventions, lowering cancer care costs and improving patient outcomes.”

The project optimizing margin identification with a fast-acting, high-resolution microscope, effective fluorescent stains for dying tumor margins, and artificial intelligence algorithms.

AccessPath is a collaboration between Rice and MD Anderson Cancer Center, other awardees in the grant include the University of Texas Health School of Dentistry, Duke University, Carnegie Mellon University and 3rd Stone Design.

“AccessPath is exactly the kind of life-changing research and health care innovation we are proud to produce at Rice, where we’re committed to addressing and solving the world’s most pressing medical issues,” Ramamoorthy Ramesh, Rice’s executive vice president for research, says in the release. “Partnering with MD Anderson on this vital work underscores the importance of such ongoing collaborations with our neighbors in the world’s largest medical center. I am thrilled for Rebecca and her team; it’s teamwork that makes discoveries like these possible.”

Rice-led initiative looks to make cancer detection affordable, equitable

future of health care

A new initiative from two Houston organizations is hoping to develop affordable health care innovation for early cancer detection.

The Center for Innovation and Translation of POC Technologies for Equitable Cancer Care, or CITEC, will be managed through Rice360 Institute for Global Health Technologies, which is part of an ongoing international effort to prepare the future global health workforce.

Rice will be joined by Baylor College of Medicine, University of Texas MD Anderson Cancer Center, University of Sao Paulo, Barretos Cancer Hospital in Brazil, Mozambique Ministry of Health, and Universidade Eduardo Mondlane in Maputo, Mozambique.

“While early detection and treatment of cancer can improve survival, available tests for early cancer detection are too complex or too expensive for hospitals and clinics in medically underserved areas,” CITEC co-principal investigator Rebecca Richards-Kortum, a Rice bioengineering professor and director of Rice360, says in a news release.

The project is part of a five-year grant from the National Institutes of Health to launch a top-tier research center in the Texas Medical Center to develop point-of-care technologies that improve early cancer detection in low-resource in America and internationally that are effective and affordable. Rice’s leading collaboration group to help secure the grant includes engineers, oncologists and international global health partners from three continents. in low-resource settings in the United States and other countries.

CITEC will aim to target development of POC tests for oral, cervical and gastrointestinal cancers through the first-year grant from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) of $1.3 million—up to $6.5 million over five years. CITEC is funded by a NIBIB grant.

Last month, NIBIB announced that CITEC will be one of six research centers that it will support, along with an additional center, through its Point of Care Technology Research Network (POCTRN).

Dr. Sharmila Anandasabapathy, vice president of global health at Baylor College of Medicine, and Tomasz Tkaczyk, bioengineering professor at Rice, are the other two cco-principals on the initiative.

“CITEC will identify needed technologies, accelerate their development, evaluate their performance and impact in diverse settings and train local users and technology developers to create and disseminate more equitable POC technologies,” Anandasabapathy says in the release.

Rice University students collaborate on COVID-19 solutions

game changers

An annual program with Rice University and its partners in Africa had to do things differently in light of the COVID-19 pandemic. Not only did operations have to shift to a virtual approach, but the projects themselves instead addressed the needs created by the disease.

Rice 360˚ Institute for Global Health, which collaborates with the Malawi University of Science and Technology (MUST) and the University of Malawi, The Polytechnic (Poly), continued their annual programming virtually over six weeks. The collaboration brings students together to solve global health issues, and this year's issue to address was overwhelmingly COVID-19.

"We had to give a lot of thought to whether we might have to cancel the program, and that was really heartbreaking to think about," says Rice 360˚ Director Rebecca Richards-Kortum, professor of bioengineering, in a news release. "Back in those days of late March and early April, I never really imagined how wonderful the virtual internship program could be."

Thirteen undergraduate interns and eight teaching assistants from Rice and Malawi, worked on six different projects, and three were presented in an online event on July 16. Here were the projects that were presented.

  • A disinfecting system that has the capability to sterilize multiple N95 masks at once. The system uses ultraviolet lights that can kill the coronavirus in around 30 minutes. Alternatively, the project included a smaller version that could be powered by solar energy. Yankholanga Pelewelo of MUST, Carolyn Gonawamba of Poly, and Andrew Abikhaled and Bhavya Gopinath of Rice developed the technology.
  • A walk-in decontamination unit that can decontaminate up to 3,000 people per day. The team of interns developed a prototype that consisted of PVC frame covered in plastic with nozzles to spray disinfectant. The project has already received interest from labs and hospitals for the device. Team members included Brenald Dzonzi of Poly, Mwayi Yellewa of MUST, and Kaitlyn Heintzelman, Krystal Cheung, and Sana Mohamed of Rice.
  • A redesigned intubation box that gives doctors better access to patients during the procedure. More than half of the 3,000 health care workers who have died from the coronavirus were doctors who focused on respiratory procedures, the team pointed out, and this daunting fact calls for redesigned tools. In total, the student innovators pitched three different designs that each included armholes in the sides, with a third hole on top to let a clinician or nurse assist with the procedure. The student team consisted of Chikumbutso Walani of Poly, Ruth Mtuwa of MUST, and Lauren Payne and Austin Hwang of Rice.

The other three projects included in the program but didn't present were designs for face shields, a hand sanitizer station and a contactless temperature monitor. All of the projects were led by teaching assistants Aubrey Chikunda and Chisomo Mukoka from MUST; Hannah Andersen, Nimisha Krishnaswamy, Alex Lammers and Ben Zaltsman of Rice; and Hope Chilunga and Francis Chilomo from Poly.

While pivoting the program to virtual comes with its challenges, Maria Oden — a professor of bioengineering, director of Rice's Oshman Engineering Design Kitchen and director of Rice 360˚ — recognizes the opportunities it provides as well.

"It would have been easy and understandable to cancel this internship, but that's not what happened, and look what the result was," Oden says in the release. "Over 90 people have tuned in to see the work of the interns. That's something we've never achieved with our in-person internships. We can learn from this experience."

UH med school granted $2M gift to offer student scholarships

scholarship gift

A new scholarship endowment aims to support students in the University of Houston’s recently established medical school.

The University of Houston’s Tilman J. Fertitta Family College of Medicine received a planned estate gift commitment estimated at $2.1 million to establish the Bob Diehl and Teresa Evans Diehl Scholarship Endowment. The scholarship will assist full-time medical students who demonstrate financial need and meet academic standards.

“Endowed scholarships like this do more than ease the burden of tuition—they empower our students to focus on learning, leadership and compassionate care,” Jonathan McCullers, UH vice president of health affairs and dean of the Fertitta College of Medicine, said in a news release. “We are deeply grateful to the Diehls for their vision and commitment to expanding access to health care through education.”

The endowment aims to provide annual scholarship support for students enrolled in the Fertitta College of Medicine. The gift also aligns with the university's fundraising initiative focused on expanding opportunities for students, known as Can’t Stop Houston: The Centennial Campaign, which works to expand research ahead of UH’s 100th anniversary next year.

The Diehls are both graduates from UH, and Bob Diehl spent 38 years working at UPS.

“It brings me happiness to know that my endowment will make a difference in young people's lives and in the communities that will need those future doctors,” he said in the release.

The Fertitta College of Medicine welcomed its inaugural class of 30 students in 2020 and expects classes to grow to 120 students in the coming years, according to UH. The university believes scholarship opportunities will be crucial for students to pursue medical education despite financial challenges.

“The Diehl family’s generosity will open doors for talented future physicians who are called to serve our communities but may otherwise face financial barriers to pursuing a medical education,” McCullers added.

Houston medtech firm secures $30M for neurosurgical robot

stroke surgery

Robotic neurosurgery is an exciting new frontier in medicine, and Houston-based medtech firm XCath is leading the charge with its revolutionary Iris robotic system. The company announced in March that it had secured $30 million in Series C funding to continue developing systems to tackle blood clots in the human brain.

“We are grateful to our investors for their conviction in our shared mission to improve clinical outcomes for patients impacted by endovascular diseases,” Eduardo Fonseca, CEO of XCath, said in a news release. “In 2025, the XCath team advanced the frontiers of endovascular robotics. This funding accelerates our commitment to expanding access to life-saving care so that where a patient lives no longer determines whether they live.”

XCath–which also has campuses in Pangyo, South Korea–has already achieved a number of remarkable firsts in robotic neurosurgery. The Iris is the only endovascular robotic system currently in development to perform intracranial navigation or neurointerventional treatment, and is the only robot in the world to have performed an intracranial neurovascular procedure involving the robotic manipulation of three devices.

These new Series C funds, which bring the company's total investment to $92 million, will go toward developing a clinical telerobot capable of performing a mechanical thrombectomy. This would bring unprecedented accuracy and precision to the surgical removal of brain clots, significantly reducing the risk of neurosurgery.

“Robotic surgery succeeds when innovation is paired with practical execution,” Dr. Fred Moll, chairman of the XCath board of directors, said in the release. “XCath has built a promising technology foundation, and just as importantly, a team that values rigor and appreciates perspective. I’m excited to support them as they take on the mission of globalizing access to gold-standard care for stroke patients.”

In November 2025, the Iris debuted under the control of Dr. Vitor Mendes Pereira at The Panama Clinic in Panama City, alongside local Principal Investigator Dr. Anastasio Ameijeiras Sibauste. It was only the second time in human history that a robot had been used for intracranial neurovascular intervention, and it established Iris as a viable technology in the fight against stroke.

“Treatment of stroke and other neurovascular diseases represents one of the most significant financial opportunities in healthcare, supported by positive reimbursement dynamics and strong demand from health systems,” Nicholas Drysdale, CFO of XCath, added in the release. “With our continued investor support and disciplined capital deployment, XCath is positioned to build a category-leading platform in endovascular robotics”.
