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.

The first patient has been enrolled in a nationwide clinical trial that will evaluate the safety of Houston-based Saranas’ device for early detection of bleeding during minimally invasive heart procedures.

The initial patient was enrolled earlier this month at Morristown Medical Center in Morristown, New Jersey. The trial will eventually enroll up to 265 patients across the U.S.

Saranas’ Early Bird Bleed Monitoring System aids the detection of bleeding during high-risk percutaneous coronary intervention (PCI) procedures using mechanical circulatory support (MCS). In the clinical trial, the MCS will be the Impella heart pump.

PCI refers to minimally invasive procedures for opening clogged coronary arteries. MCS boosts heart function when the organ can’t perform at its best. The trial will test the ability of the Early Bird Bleed Monitoring System to detect serious or potentially fatal bleeding.

“As the field of minimally invasive, catheter-based procedures continues to advance, patient safety is paramount,” Dr. Babar Basir, director of acute mechanical circulatory support at Detroit’s Henry Ford Health System and co-principal investigator of SAFE-MCS, says in a news release. “This study will collect comprehensive procedural data in patients undergoing PCI with MCS.”

The data then will be reviewed to determine how real-time monitoring of bleeding can improve a patient’s health, Basir says.

Dr. Philippe Généreux, co-director of the Structural Heart Program at Morristown Medical Center, is the other co-principal investigator for the clinical trial.

“SAFE-MCS is the first prospective trial focused exclusively on the impact of integrating bleed monitoring in large-bore access for high-risk protected PCI patients,” says James Reinstein, president and CEO of Saranas, a medical device startup.

About one-fifth of patients will experience bleeding complications during “large bore” blood vessel procedures such as percutaneous MCS, transcatheter aortic valve replacement, and endovascular aneurysm repair. The estimated cost of one bleeding complication during these large-bore procedures is $18,000, adding up to an annual cost of $729 million for health care providers.

The Early Bird Bleed Monitoring System is the first and only device approved by the U.S. Food and Drug Administration (FDA) for real-time monitoring of bleeding problems during endovascular procedures for repair of blood vessels.

Saranas’ collaborators in the clinical trial are Proxima Clinical Research, a Houston-based contract research organization, and South Korea’s CardioVascular Research Foundation. The Early Bird study is expected to be completed by January 2023.

Since being founded in 2013, Saranas has collected $31.5 million in funding. This includes a $12.8 million Series B round that Saranas received this summer 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. Click here to read more.

Founded by Tatiana Fofanova, Dr. Desh Mohan, and Katelin Cherry, Koda Health uses AI to help patients create advance medical care directives and documents—such as a living will—through an easy to use web-based interface.

The app then autogenerates legal and medical documents, which patients can notarize or electronically witness the forms through the app or on their own.

According to Fofanova, who earned her PhD in in Molecular Medicine at Baylor College of Medicine in Houston and now acts as the company's CEO, what historically has been a time consuming and expensive process, through Koda Health, takes an average of 17 minutes and is completely free of charge to the end user.

"We hope to reduce any outstanding barriers to access that might exist," Fofanova says. "It is very frequently the oldest and the poorest that are the highest utilizers of health care that don't have access to these solutions." Click here to read more.

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.

This Houston airport saw sharp passenger decline in 2025, study shows

Travel Talk

A new global airport travel study has revealed passenger traffic at Houston's William P. Hobby Airport (HOU) sharply decreased from 2024 to 2025.

The analysis from travel magazine LocalsInsider examined recently released data from the Bureau of Transportation Statistics (BTS), the U.S. International Trade Association, and a nationwide survey to determine the following American traveler habits: The most popular U.S. and international destinations, emerging hotspots, and destinations on the decline. The study covered passenger travel trends from January through July 2025.

In the report's ranking of the 40 U.S. airports with the sharpest declines in passenger traffic, HOU ranked 13th on the list.

About 4.26 million arrivals were reported at HOU from January through July 2024, compared to about 3.96 million during the same seven-month period in 2025. According to the data, that's a significant 7.1 percent drop in passenger traffic year-over-year, or a loss of 300,974 passengers.

"As travelers chase new hotspots, some destinations are seeing reduced passenger traffic whether due to rising costs, shifting airline schedules, or evolving traveler preferences, some destinations are seeing a decrease in visitors," the report's author wrote.

It appears most major Texas airports had drops in passenger traffic from 2024 to 2025. Dallas Love Field Airport (DAL) saw the worst in the state, with a dramatic 7.4 percent dip in arrivals. DAL also ranked 11th on the list of U.S. airports with the steepest declines in passenger traffic.

More than 5.13 million arrivals were reported at DAL from January through July 2024, compared to over 4.75 million during the same seven-month period in 2025.

This is how passenger traffic has fallen at other major Texas airports from 2024 to 2025:

Austin-Bergstrom International Airport (AUS):

  • 6,107,597 – Passenger arrivals from January to July 2024
  • 5,828,396 – Passenger arrivals from January to July 2025
  • -4.6 percent – Year-over-year passenger change
Dallas/Fort Worth International Airport (DFW):
  • 23,830,017 – Passenger arrivals from January to July 2024
  • 23,251,302 – Passenger arrivals from January to July 2025
  • -2.4 percent – Year-over-year passenger change

San Antonio International Airport (SAT):

  • 2,937,870 – Passenger arrivals from January to July 2024
  • 2,836,774 – Passenger arrivals from January to July 2025
  • -3.4 percent – Year-over-year passenger change
El Paso International Airport (ELP):
  • 1,094,431 – Passenger arrivals from January to July 2024
  • 1,076,845 – Passenger arrivals from January to July 2025
  • -1.6 percent – Year-over-year passenger change

NASA names new chief astronaut based in Houston

new hire

NASA has a new chief astronaut. Scott Tingle, stationed at the space agency’s Johnson Space Center in Houston, assumed the post Nov. 10.

Tingle succeeds NASA astronaut Joe Acaba, who had been chief astronaut since February 2023. Acaba now works on the staff of the Johnson Space Center’s director.

As chief astronaut, Tingle runs NASA’s Astronaut Office. His job includes developing astronauts’ flight crew operations and assigning crews for space missions, such as Artemis missions to the moon.

Tingle, a former captain in the Navy, was named a NASA astronaut candidate in 2009. He has logged over 4,500 flight hours in more than 50 aircraft.

Tingle was a flight engineer aboard the International Space Station, where he spent 168 days in orbit during two expeditions that launched in December 2017. Since returning to Earth, he has held various roles in the Astronaut Office, including mission support, technical leadership and crew readiness.

Before joining NASA, Tingle worked in El Segundo, California, on the technical staff of The Aerospace Corp., a nonprofit that supports U.S. space programs.

Tingle recalls expressing his desire to be an astronaut when he was 10 years old. It took him four tries to be accepted by NASA as an astronaut candidate.

“The first time I figured it was kind of too early. The second application, they sent out some feelers, and that was about it. Put in my third application, and got a couple of calls, but it didn’t quite happen,” Tingle said in an article published on the website of Purdue University, his alma mater.

ExxonMobil officially pauses plans for $7B Baytown hydrogen plant

Change of Plans

As anticipated, Spring-based oil and gas giant ExxonMobil has officially paused plans to build a low-hydrogen plant in Baytown, Chairman and CEO Darren Woods told Reuters in late November.

“The suspension of the project, which had already experienced delays, reflects a wider slowdown in efforts by traditional oil and gas firms to transition to cleaner energy sources as many of the initiatives struggle to turn a profit,” Reuters reported.

Woods signaled during ExxonMobil’s second-quarter earnings call that the company was weighing whether it would move forward with the proposed $7 billion plant.

The Biden-era Inflation Reduction Act created a new 10-year incentive, the 45V tax credit, for production of clean hydrogen. But under President Trump’s "One Big Beautiful Bill Act," the window for starting construction of low-carbon hydrogen projects that qualify for the tax credit has narrowed. The Inflation Reduction Act mandated that construction start by 2033. But the Big Beautiful Bill switched the construction start time to early 2028.

“While our project can meet this timeline, we’re concerned about the development of a broader market, which is critical to transition from government incentives,” ExxonMobil Chairman and CEO Darren Woods said during the company’s second-quarter earnings call.

Woods had said ExxonMobil was figuring out whether a combination of the 45Q tax credit for carbon capture projects and the revised 45V tax credit would enable a broader market for low-carbon hydrogen.

“If we can’t see an eventual path to a market-driven business, we won’t move forward with the [Baytown] project,” Woods said.

“We knew that helping to establish a brand-new product and a brand-new market initially driven by government policy would not be easy or advance in a straight line,” he added.

ExxonMobil announced in 2022 that it would build the low-carbon hydrogen plant at its refining and petrochemical complex in Baytown. The company has said the plant is slated to go online in 2027 and 2028.

ExxonMobil had said the Baytown plant would produce up to 1 billion cubic feet of hydrogen per day made from natural gas, and capture and store more than 98 percent of the associated carbon dioxide. The plant would have been capable of storing as much as 10 million metric tons of CO2 per year.
