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.”

Why this Houston medical device innovator is pumped up for the first total artificial heart

HOUSTON INNOVATORS PODCAST EPISODE 248

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.

The difference with BiVACOR's device is it abandons the bladder approach. Cohn explains that as assist pumps evolved — something his colleague, Dr. Bud Frasier, had a huge impact on — they featured new turbine and rotor technology. Daniel Timms, BiVACOR's founder and CTO, iterated on this technology beginning when he was a postdoctoral student at Queensland University of Technology in Australia.

"BiVACOR is the first artificial heart that leverages what we learned from that whole period — it has no bladders, it has no valves. It has one moving part, and that moving part is suspended in an electromagnetic field controlled by a computer and changed thousands of times a second," Cohn says. "It will never wear out, and that's why we think it's the world's first total artificial heart."

The company is seeing momentum, celebrating its first successful human implantation last month. The device was used for eight days on a patient at Baylor St. Luke’s Medical Center before the patient received a heart transplant.

Cohn says that BiVACOR has plans to use the TAH as "bridge-to-transplant" device in several other surgeries and expects to get FDA approval for that purpose in the next three to four years before working toward clearance for total artificial heart transplants.

Cohn has worked to support medical device startups at CDI at TMC for the seven years it has existed — first under Johnson and Johnson and then under TMC when it took the program over. He describes the center and its location as the ideal place for developing the future of health care, with Houston rising up to compete with regions known for medical device success — both coasts and Minnesota.

"Being in the shadow of the largest medical center on the planet — 106,000 employees show up there every 24 hours," Cohn says, "if you want to innovate, this is the place to do it."

Health care leader says Houston's innovation ecosystem is shifting into third gear

houston innovators podcast episode 113

It's never been a better time for health care innovation in Houston. At least, that's what Dr. Toby Hamilton as observed in his time as a health care startup founder and innovation leader in Houston.

"Houston is absolutely beginning to show up on the national radar regarding health care innovation — as we should," Hamilton says on this week's episode of the Houston Innovators Podcast. "We are shifting our innovation vehicle into third gear for the first time, and I'm excited to see what fourth gear looks like, because it's around the corner.

Hamilton started his career as a physician before founding Emerus Holdings, a micro-hospital system in the Houston area which later exited to private equity. He also founded a nonprofit focused on connecting hospital innovation leaders called the Healthcare Innovators Professional Society and led the Texas Medical Center's Biodesign program for two years.

Over the years, he says he's seen the potential develop for Houston to hold a significant role in health care innovation across the world — it's just going to take all hands on deck.

"As a community, if we can get behind that vision and be the place that tests, develops, and creates opportunities, Houston has the potential to be unlike anything in the world," he says on the show.

Hamilton hopes to contribute to that momentum and his latest endeavor is tackling a huge obstacle in health care: access. He founded Hamilton Health Box in 2019 and had a full year of operations including a pilot program before the COVID-19 shutdown.

Essentially, Hamilton's vision recreates the traditional method of providing health care access to a company's employee base. The program brings an on-site care team to the company's offices so that employee patients have immediate access to treatment and preventative care.

"Hamilton Health Box that was designed to deliver the lowest possible price of primary and preventative care," Hamilton says. "We built that to be able to take that care to the jobsite and meet the customer where they are at."

In the new year, Hamilton says he hopes to expand on this model and reach groups of people without access to this type of care — like in rural communities.

Texas grocer H-E-B finally rolls out digital tap-to-pay services

hi, tech

Texas' favorite grocery store has some good news for shoppers who have a habit of forgetting their wallets. H-E-B is starting a phased rollout for digital tap-to-pay services, starting in San Antonio before spreading to the rest of the chain's stores.

The rollout began Monday, October 7. A release says it'll take "about a week" to spread to all stores in the region before making it ways across Texas. Although it is not known which stores will add the service on what date, the rollout includes all H-E-B stores, including Mi Tienda, H-E-B's Mexican grocery store that has locations in Houston.

With tap to pay, shoppers will finally be able to use smartphone-based systems such as Apple Pay, Samsung Pay, and Google Pay, as well as tapping a physical card.

Payments can be made with those apps, or "digital wallets," at cash registers and self-checkout lanes, as well as restaurants and pharmacies within H-E-B stores. They won't be accepted right away at H-E-B fuel pumps, but customers can use them to pay for gas if they bring their phones to the fuel station payment window.

This isn't exactly cutting-edge technology; Google Wallet launched in 2011, leading the market, and was followed by Apple Pay in 2014. But it's not ubiquitous either. In 2023, a poll by Forbes Advisor found that barely more than half of respondents used digital wallets more than traditional forms of payment.

H-E-B is on a bit of a payment revolutionizing kick, also launching a debit card in 2022 and a partnership in August of 2024 with the H-E-B-owned delivery service Favor for its fastest order fulfillment yet. Central Market and Joe V’s Smart Shop, two other H-E-B brands, also recently launched tap to pay.

“At H-E-B, we’re always exploring a broad range of technologies to enhance how customers shop and pay for products,” H-E-B vice president Ashwin Nathan said in a statement. “This has been one of the most requested services we have received from our customers and partners, and we are excited to now make this popular technology available at all our H-E-B locations.”
