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.

Houston Innovation Awards honor Don Kendall Jr. with posthumous Trailblazer Legacy Award

lasting legacy

Every year, the Houston Innovation Awards honor one Houstonian with the Trailblazer Award, whose impact is felt throughout the city's innovation and business ecosystem.

This year, the Trailblazer Legacy Award will be given posthumously to Don Kendall Jr., who died in September while on a trip to the Republic of the Congo with the Jane Goodall Institute, one of the many organizations he was deeply involved with.

Kendall's obituary puts it simply: "Don’s truest passions were conservation and his family." Many saw those passions play out in his career, particularly in the role he played in shaping Houston's clean energy sector.

Kendall served as general partner of New Climate Ventures, a Houston-based early-stage venture capital firm that invests in next-gen energy, materials and fuel technologies and startups. The firm's portfolio includes Houston-based clean energy companies like Solidec, Syzygy Plasmonics and Rheom Materials.

Kendall was also founding managing director and CEO of Kenmont Capital LP. He ran a $500 million distressed debt and credit-based hedge fund focused on the energy, power and transportation sectors and one of the top-performing private equity funds under the Kenmont umbrella.

He served on the board of Talos Energy, American Midstream Partners, Syzygy Plasmonics, Tangent Energy, Stream Energy and others. Notably, he served as Chair of the Special Committee of the SolarCity board during its acquisition by Tesla in 2016. According to his obituary, Kendall negotiated with "Elon Musk in the middle of the night on a rickety pier in Indonesia after eluding a poisonous snake."

Outside of the clean energy space, Kendall also served on the boards of the Jane Goodall Institute, Earthwatch International and Ecological Defense Group. He also served as vice chair of the Houston Zoo Inc. and chair of its Conservation Committee.

Kendall was selected by our esteemed panel of judges to receive the 2026 Trailblazer Legacy Award. The panel includes carbon removal entrepreneur and CEO of Houston-based Mars Materials Aaron Fitzgerald.

Fitzgerald shares the profound impact Kendall had on his career and those of many others.

"Honoring Don with the Trailblazer Legacy Award is a fitting tribute to a leader whose impact spanned civic work with the Houston Zoo, wildlife conservation, and the growth of our startup ecosystem," Fitzgerald says. "He paired a keen eye for potential with the relentless drive to unlock it. For Mars Materials, his early backing carried us through a critical valley when we needed belief the most, and his presence as a personal mentor is profoundly missed."

Don was an avid traveler, cyclist and collector. He is survived by his wife of 50 years, Diane S. Kendall. A celebration of life will be held early in 2027.

2 Houston suburbs rank among 5 best cities to retire, says U.S. News

Slowing Down

Houston and nine of its suburbs are earning new acclaim on U.S. News and World Report's just-released list of the best U.S. cities for retirees in 2027. Two northern suburbs, The Woodlands and Spring, are resting easy among the top five nationwide.

The 2027 Best Places to Retire list evaluated over 850 U.S. cities based on six livability metrics that best serve American retirees: quality of life, affordability, health care, retiree taxes, job market, and population and migration. The top 250 finalist cities were then ranked nationally and by city size.

Midland, Michigan topped the list for the second consecutive year and is followed by Homosassa Springs, Florida (No. 2) and Weirton, West Virginia (No. 3).

The Woodlands and Spring respectively maintained their standings as the No. 4 and No. 5 best cities for retirees for the second year in a row. The Woodlands topped the separate list of the best midsized U.S. cities to retire, while Spring landed 5th among the smallest U.S. cities.

Houston proper was declared the No. 2 best big city for retirees, and it ranked 89th overall. Elsewhere in the metro, Pearland (No. 13) and Conroe (No. 14) ranked just outside the overall top 10 but ranked 4th and 5th among the best midsized cities for retirees.

U.S. News said affordability is the "most considered factor" when it comes to picking the best place to live a low-stress retirement life, and that's what Houston and its neighbors deliver. Affordable cities also give retirees "a sense of security and comfort as they live out their golden years," according to Megan Wood, U.S. News assistant managing editor of home services and real estate.

"It’s no secret that affordability is top of mind for Americans this year, which is why U.S. News updated its weighting criteria to better align with what retirees prioritize," Wood said. "The 2027 rankings reflect key metrics used to highlight the places that
best suit retiree needs."

Sugar Land was declared the 10th best place to live in the U.S. in a separate U.S. News report earlier this year, but it doesn't quite meet the expectations for retirees. This particular suburb ranked as the 45th best overall city to retire, but it fared better in the city size ranking and landed 13th among the biggest U.S. cities.

Pasadena also surprised as the 85th best place to retire nationwide in this report, despite being hailed as the No. 3 best city to retire in Texas by RetirementLiving.com.

Three more Houston neighbors ranked among the top 100 overall best places to retire for 2027: League City (No. 25), Missouri City (No. 49), and Baytown (No. 88).

These are the top 10 best U.S. cities to retire for 2027:

No. 1 – Midland, Michigan
No. 2 – Homosassa Springs, Florida
No. 3 – Weirton, West Virginia
No. 4 – The Woodlands
No. 5 – Spring, Texas
No. 6 – Rio Rancho, New Mexico
No. 7 – Altoona, Pennsylvania
No. 8 – Paducah, Kentucky
No. 9 – Lynchburg, Virginia
No. 10 – Palm Coast, Florida
