The FENIX® Continence Restoration System is a small, flexible band of interlinked titanium beads with magnetic cores. The magnetic attraction between the beads augments the anal sphincter, creating a barrier to involuntary passage of faecal matter (Fig. 1). The magnetic bond is temporarily broken to allow the voluntary passage of stool and restored immediately thereafter (Fig. 2).
The FENIX® System is placed around the anal sphincter during a surgical procedure that requires a single incision and is usually completed in one hour. A customized sizing tool is used to ensure the correct size device is selected. Once the correct size is confirmed using x-ray, the FENIX® System is implanted and secured by tying sutures together. The correct size is again confirmed using x-ray. Patients generally go home the day after surgery.
