# Motasim Sirhan

> Motasim Sirhan is an engineer, repeat medical-device founder, and the founder and CEO of Elixir Medical. After early work at Guidant on catheter and stent technologies, he founded and exited Avantec Vascular, co-founded Maya Medical, and built Elixir around a long-running question: whether a coronary implant can restore blood flow without permanently fixing an artery in place. That effort produced the DynamX bioadaptor, a device designed to unlock after its polymer coating resorbs while retaining dynamic vessel support.
