Daniel Pelak, a former chief executive officer at InnerPulse and Closure, has joined the board of directors at medical device startup,

Mardil is developing technology to treat cardiac problems, such as mitral valve regurgitation. The company’s technology is now being testing in human trials.

"Dan has a long history as a senior executive in the medical device industry, garnering multiple successes in growing young companies and managing corporate operating divisions," said Jai Ramon, a doctor and co-founder of Mardil in 2002. He also is a professor of surgery and director of adult cardiac surgery and cardiothoracic surgical research at the University of Chicago. "He has a wealth of experience commercializing cardiac devices, and we look forward to adding someone with Dan’s background to our board,” Ramon added in a statement.

Madril’s device is being tested in India. It is called BACE, which stands for basal annuloplasty of the cardia externally. The device surrounds the heart and is designed to be less invasive and less expensive while also reducing side effects from current heart valve repair and replacement techniques.

"The BACE device is truly a breakthrough technology that has the potential to change the way we treat heart valve disease," Pelak said in a statement. "I am excited to be affiliated with a company that has successfully developed a truly novel alternative to invasive valvular replacement, and I look forward to contributing my skills toward advancing this therapy."

Pelak is an adviser with Welsh, Carson, Anderson and Stowe, a private equity firm.
