Abstract
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.
