A constriction device that constricts body tissue includes fixation structures for fixing the device on constricted body tissue. The device includes an elongated sleeve including an inner surface and opposed opened ends. The device is formed from expandable or elastic material so that when in an expanded condition, body tissue to be constricted may be received therein and thereafter, when released from the expanded condition, the body tissue is constricted by the device. The fixation structures include a plurality of fixation elements on the inner surface of the sleeve that grasp the body tissue upon release of the sleeve from the expanded condition to fix the device on the constricted tissue.

Constriction device including fixation structure

A constriction device that constricts body tissue is configured to be safely sutured to constricted body tissue. The device includes a generally cylindrical elastic sleeve including opposed opened ends and having a wall of substantially uniform thickness that receives body tissue therein to be constricted. The sleeve includes a plurality of suture holes to receive a suture to maintain the sleeve the tissue constricted by the sleeve. The sleeve includes a suture hole reinforcement structure, as for example an increased wall thickness, about each suture hole to permit the device to be sutured to constricted body tissue without damaging the device.
