Houston-based medical device company Saranas has tapped a veteran of the healthcare industry as its new CEO.

Mike MacKinnon most recently was president and partner at Madison Ventures +, a private equity firm based in Greenwood Village, Colorado. The firm invests in companies in healthcare, real estate, finance, and other sectors.

Before joining Madison Ventures +, MacKinnon was CEO of Zidan Medical, a startup focused on treatment of airway lesions in patients with early stage lung cancer. He served in that role from 2019 to 2023.

Earlier, he was CEO of ROX Medical, a medical device company specializing in minimally invasive vascular therapy for patients with uncontrolled high blood pressure. He held that role from 2018 to 2019. He previously worked at Philips North America, Volcano, AtheroMed, Hansen Medical, Access Closure, and FoxHollow Technologies.

In a news release, Dan Wolterman, chairman of Saranas’ board and former president and CEO of Memorial Hermann Health System, calls MacKinnon “an accomplished executive with an impressive record of bringing disruptive technology to market, guiding strategy, and driving significant growth.”

Now president and CEO of Nashua, New Hampshire-based medical device company Conformal Medical, James Reinstein was president and CEO of Saranas from 2020 to 2022. Prior to Reinstein, Zaffer Syed held that position from 2017 to 2020. He's still an adviser for the company and recently announced his role as entrepreneur in residence at the Texas Medical Center.

Saranas is working on commercializing its Early Bird Bleed Monitoring System, touted as the first and only system FDA-approved bleeding detection system for procedures involving blood vessels. It is designed to detect bleeds early, enabling physicians to reduce medical risks and potentially avoid costly medical problems.

“Bleeding remains a common issue during and after endovascular procedures and can result in life-threatening complications,” says MacKinnon.

Since being founded in 2013, Saranas has treated over 1,200 patients with its device and has received $29.2 million in funding, according to Crunchbase. This includes a $12.8 million Series B round that Saranas got in 2021 from Chicago-based Baird Capital and Austin-based S3 Ventures.

The Early Bird device was developed at Houston’s Texas Heart Institute. The FDA approved the device in 2019.

When James Reinstein took the helm of Houston-based Saranas in March 2020, he was tasked with taking the medical device company through its series B funding round and into larger clinical trials. Navigating these tasks during a global pandemic wasn't part of the plan.

"There was just so much uncertainty," Reinstein says on this week's episode of the Houston Innovators Podcast. "All of the funds didn't know which end was up, what hospitals would be doing, what procedures were going to begin again."

Saranas received FDA approval and began its clinical trials for its Early Bird Bleed Monitoring System in 2019. The device is designed to detect and track bleeding complications related to endovascular procedures. These medical procedures treat problems, such as aneurysms, that affect blood vessels. Around 20 percent of patients suffer a bleeding complication during endovascular procedures.

Reinstein explains that the way health tech funding trended over the past 18 months greatly affected Saranas. The device fell outside the parameters of what investors were looking for during this pandemic time. However, Reinstein explains, the Early Bird worked and had FDA approval — that made all the difference.

"We are very confident that the product does work and it can have a significant impact for hospitals and patients," Reinstein says. "Eventually, the term sheets came in."

Saranas announced in July that it closed a $12.8 million series B investment led by Wisconsin-based Baird Capital, the venture capital and global private equity arm of Baird, a global company with a location in Houston. Austin-based S3 Ventures also supported the round.

The funds will propel Saranas into its next phase, which includes growing its team, larger trials, and a next-generation product.

Reinstein has had decades in health care innovation all over the world, with a large chunk of his career at Boston Scientific. He's seen Houston's innovation ecosystem evolve.

"I do think that there's a great potential for Houston to really develop the industry," Reinstein says. "There's just two areas that need to get fortified. One is the funding and getting the funds directed to Houston companies — with the idea that the company stays in Houston. ... The other side of the coin is really finding the talent to come in and run the companies, take on leadership positions."

Reinstein shares more details on what's next for Saranas, as well as his advice for med tech entrepreneurs and observations on Houston's innovation ecosystem on the show. Listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

Houston early bleeding detection device company reveals results of its clinical trials

blood tests

A Houston-based startup is closer to taking flight with a medical device designed to catch bleeding complications during medical procedures that involve blood vessels.

On May 22, researchers presented the results of a study showing the Early Bird Bleed Monitoring System from Houston-based Saranas Inc. detected various levels of bleeding in 63 percent of the patients who underwent endovascular procedures. These procedures treat problems, such as aortic aneurysms, that affect blood vessels.

No troubles were reported with the Early Bird device during the clinical trial, the researchers say.

Before this study, the Early Bird device hadn't been tested in humans. In all, 60 patients in five states participated in the clinical trial, which ran from August to December last year. Findings of the study were unveiled at the Society for Cardiovascular Angiography Interventions 2019 Scientific Sessions in Las Vegas.

The study's authors say they plan to continue evaluating the device at medical institutions that want to better manage bleeding during endovascular procedures.

"This is the first time we're seeing how this device could help in a real-world patient setting, and we were very encouraged by the results. Right now, patients have a risk of vessel injury when undergoing endovascular procedures where the femoral artery or vein is used for vascular access," Dr. Philippe Genereux, principal investigator for the study and a cardiologist at Morristown Medical Center in Morristown, New Jersey, says in a news release.

"This technology allows us to detect bleeding in real-time," Genereux adds, "which means we can take action quickly and improve the outcomes of the procedure and recovery for the patient."

In March, the Early Bird device — invented at Houston's Texas Heart Institute — received the U.S. Food and Drug Administration's approval as a "novel" medical device.

Saranas says Early Bird is the first and only device of its type. The FDA approval and the promising results of the clinical trial pave the way for the eventual launch of the device into the healthcare market.

A forecast from professional services firm KPMG predicts the global market for medical devices will reach nearly $800 billion by 2030. Early Bird aims to capture a sliver of that market by addressing an expensive and potentially fatal problem. One-fifth of patients experience bleeding complications during large-bore endovascular procedures. Research shows these complications are associated with a greater risk of death, longer hospital stays, and higher healthcare costs.

The Early Bird device is meant to decrease those complications by quickly alerting medical professionals to signs of bleeding during endovascular procedures.

As explained by the Texas Heart Institute, the Early Bird employs a sheath — a plastic tube that helps keep arteries and vessels open — embedded with sensors that measure the electrical resistance across a blood vessel. When the Early Bird senses a change in the electrical resistance, medical professionals receive audible and visual notifications about potential internal bleeding. If detected early, this bleeding can be minimized.

Altogether, Saranas has raised $12 million from investors, including a $2.8 million round in May 2018. The company was founded in 2013.

"What attracted me to Saranas is that our solution has the potential to meaningfully reduce serious bleeding complications that worsen clinical outcomes and drive up healthcare costs," says Zaffer Syed, who joined the startup as president and CEO in 2017. "In addition, our device may support access of important minimally invasive cardiac procedures by allowing them to be performed more safely."

Houston bio-based materials startup breaks into footwear

cleaner shoes

A more sustainable shoe can’t be built on a single material swap. From the hard plastics hidden inside a heel to the material covering a sneaker’s upper, footwear is a collection of components—and each presents a different challenge for companies trying to move away from conventional, petroleum-based materials.

Houston-based Rheom Materials wants to change that equation. The biomaterials company has launched a sustainable footwear platform featuring two of its bio-based alternatives: Benree, a biodegradable plastic designed for hard internal components, and ShoraiDura, a durable leather alternative for footwear uppers.

“A shoe is not one material; it is multiple parts working together as a system. Substituting a single material has never moved the needle,” Rheom founder and CEO Zimri Hinshaw said in a news release. “Rheom wants to make it easier for brands to make a positive impact. By providing an assortment of bio-based materials, brands can change the system, not just a swatch of it.”

Benree is Rheom’s alternative to conventional hard plastics used in footwear construction. The company says it is a 100 percent USDA-certified bio-based, biodegradable material with performance comparable to acrylonitrile butadiene styrene (ABS), a widely used engineering plastic.

The material has passed SATRA testing for high-heel applications with Bared Footwear, an Australian footwear brand.

“At Bared, we're constantly on a journey to remove plastic from our shoes. At the same time, our brand won't compromise on quality for the end customer,” Millie Richards, Bared’s head of sustainability, added in the release. “From samples and testing, Rheom has proven to be solving both of those problems for us. We look forward to seeing how they develop as a company and would love to use them in our shoes.”

Rheom says it is also exploring Benree for additional internal components, including toe puffs and heel counters.

The company’s ShoraiDura material addresses another major part of shoe construction: the upper, which must withstand repeated flexing, friction and wear while maintaining its appearance.

Containing about 80 percent bio-based content, ShoraiDura is engineered as a durable leather alternative for footwear. Rheom says the material’s molecular structure is designed to deliver the strength and durability required for demanding applications.

To demonstrate how the material could be used in finished products, Rheom worked with a Los Angeles-based footwear manufacturer to create two prototypes: an athletic sneaker and a textured skater shoe, both featuring ShoraiDura uppers.

The two offerings reflect the company’s broader strategy. Rather than asking brands to evaluate a single material in isolation, Rheom is positioning its platform as a way to explore alternatives across different parts of footwear construction.

The next step is broader industry adoption. Benree’s testing with Bared Footwear and ShoraiDura’s footwear prototypes offer early examples of how the materials could be applied, while commercial use will depend on manufacturers’ evaluations and product-development decisions.

Rheom Materials is a Houston-based biomaterials company developing bio-based alternatives to petrochemical plastics. Its product portfolio includes Shorai, a leather alternative, and Benree, a hard plastic alternative.

The company debuted Shorai at the Houston Livestock Show and Rodeo in 2025 and showed a bio-based "leather" collection in Milan earlier this year. Read more here.

UH expands Medical Center footprint with $77M research facility

breaking ground

The University of Houston broke ground on a brand new $77.5 million Medical Research Building last week that will host clinical trials and a virtual reality behavioral health suite, among other laboratories. Designed by SmithGroup, it will be the second building on the UH Medical Center campus after the Fertitta College of Medicine opened in 2022.

“The Medical Research Building was designed to foster collaboration and discovery while creating a welcoming environment for students, researchers and the community,” Kalman Nagy, higher education studio design leader for SmithGroup, said in a news release. “As the second building on the University of Houston’s medical campus, we wanted to create a strong connection to the College of Medicine and the surrounding woodlands, with outdoor terraces, shared learning spaces and natural views that inspire interaction and innovation.”

Located just behind the Fertitta building at 5150 Medical Service Drive, the 57,000-square-foot building will house wet laboratories, computational research spaces and specialized facilities for clinical research. The virtual reality behavioral health suite will use immersive technology to deliver care through manufactured audio and visual environments. It’s part of the college’s vision for developing new medical advancements in the heart of Houston’s medical community. The groundbreaking comes on the heels of the launch of the university's cross-disciplinary academic venture, UH Health, this summer.

“This groundbreaking marks an important next step in the growth of the Fertitta College of Medicine and UH Health,” Dr. Jonathan McCullers, vice president for health affairs at UH, added in the release. “We are building the research capacity to match our ambitions—bringing together scientists, physicians and experts from across the University to accelerate discovery and turn promising ideas into solutions that improve people’s lives.”

UH’s journey to establish a significant presence alongside the University of Texas and Baylor in the Medical Center started in 2009 when it became an official full institutional member. The university launched its plans for the Fertitta building in 2013, and is pursuing Health Science Center designation from the Texas Legislature in the next year’s session.

“The research that will take place here will directly benefit our community,” UH President Renu Khator added. “Diseases do not recognize disciplinary silos, and neither should our research. This building will bring together experts from across UH to break down those barriers, work across disciplines and tackle some of our most complex health challenges.”

The building is slated to open in 2028.
