About Us


Circuport, Inc, was founded by two prominent vascular surgeons, Dr. John Edoga and Dr. Thierry Richard.

Dr. John Edoga

Over the past ten years, they have developed The Circuport System based on their several decades of collective practical experience with hemodialysis patients, and as a result of their dissatisfaction with the existing access systems for such patients.
