A sling for treating urinary incontinence includes a suburethral support and first and second elongated suspending members. The suburethral support has opposite ends, is formed from a polymer and has first physical properties including a density, a length and a width. The first and second suspending members are formed from the same polymer as the suburethral support and have second physical properties including a density, a length and a width. The density of the suspending members is different than the density of the suburethral support. The first and second suspending members are each formed separately from and attached to one of the opposite ends of the suburethral support. The length of each of the suspending members is greater than the length of the suburethral support, and the width of each of the suspending members is less than the width of the suburethral support.
