A method of treating urinary incontinence includes making an incision and exposing tissue of a urethra. The method additionally includes inserting a non-porous sheet into the incision and forming a cuff around the urethra with the non-porous sheet by directing a first end of the non-porous sheet through a slot formed in a second end of the non-porous sheet. The method additionally includes directing an extending member that is attached to the non-porous sheet to a location exterior of a pelvis. The method further includes configuring the cuff to tighten around the urethra when pulling on the first end of the non-porous sheet, and configuring the cuff to be loosely positioned around the urethra when pulling on the extending member.
