The present invention relates to a urethral sling for treating incontinence, including methods of manufacturing the sling; methods of implanting the sling and methods of adjusting the sling both during and after installation. More specifically, the sling includes a collapsible tubular mesh of fibers designed to support the urethra and allow for tissue growth while easily conforming to the patient. The sling is pre-sized to eliminate the need for cutting to width during manufacture or installation and, thereby, eliminating the risk of creating rough or sharp edges. It is further equipped with one or more installation features for facilitating installation and securing the sling within the patient.
