Abstract
Abstract The present invention relates to prefabricated urethral suspension slings, methods of making the slings, methods of attaching suture to the slings, kits comprising the slings, and methods of using the slings to treat urinary incontinence. The slings comprise a biocompatible material having an elongate shape adapted for urethral suspension. The material has a central portion extending longitudinally between a first end portion and a second end portion. Each end portion of the sling contains at least one suture receiving site. The suture receiving sites are formed prior to surgery and may be reinforced through a variety of means. Sutures may be attached to the suture receiving sites during the manufacturing process or by the physician prior to or during surgery. Additionally, the end portions of the sling containing the suture receiving sites may be thicker than the central portion of the sling.
