Abstract
Abstract A sling device for surgical implantation into human recipient to support the urethra, the sling including an elongated strip of supple material. The elongated strip has a center portion, opposite first and second side portions, and a slot passing through the center portion, through which one of the side portions can pass, thereby forming a loop in the elongated strip. The material is a biological acceptable material for implantation into the human recipient, preferably selected from the group consisting of synthetic polymers, processed animal tissues, and combination thereof. A method of reducing the incidence of involuntary urination or restoring urinary continence in an incontinent human subject is also disclosed, including the steps of providing a sling device of the type previously described and surgically implanting the sling device in the human subject so that the urethra is biased upward so as to elevate the urethra.
