GALWAY, Ireland — Signum Surgical has named medical device veteran Mark J. Foley as chairman of the board as the company expands commercialization of its BioHealx technology for colorectal conditions.
The company said Foley brings more than three decades of experience in scaling healthcare and medical technology businesses across U.S. and international markets, joining at a time when adoption of its flagship product is growing.
BioHealx, which has been available in the United States for about six months, is designed to treat anal fistulas, a chronic and often recurring condition affecting roughly one in 5,000 people worldwide. The minimally invasive device features a bioabsorbable helical implant that applies controlled compression to close the fistula tract within the sphincter muscle.
According to the company, clinical data show an 84.4 percent success rate, while preserving continence and improving patient quality of life. Signum Surgical said the technology offers a potential alternative to traditional surgical treatments, which can involve higher risks and less consistent outcomes.
“We are delighted to welcome Mark as Chairman of the Board at this pivotal stage of our expansion. His track record of building transformative technologies and scaling successful medical device companies will be instrumental as we grow our commercial footprint and bring BioHealx to more patients and physicians worldwide,” said Carol A. Burns, president and chief executive officer of Signum Surgical.
“Signum Surgical is delivering an innovative solution for patients suffering from anal fistulas. With strong clinical outcomes, including high success rates and maintaining continence, BioHealx represents an important advancement in colorectal care. I am excited to join the company as it builds on its early commercial success and expands its reach,” Foley said.
Foley has held senior leadership and board positions at several high-growth medical technology companies, including Zeltiq and Revance Therapeutics, where he contributed to strategic expansion and commercial development. The company said his appointment reflects its focus on strengthening leadership as it continues to scale operations and broaden adoption of its technology.
