Abstract

A medical implant and method for implantation of the same. One embodiment is an implant for use in the treatment of stress urinary incontinence that includes an implantable, elongated tape having a multiplicity of openings formed through the thickness thereof, the tape having a first end region and a second end region longitudinally opposite the first end region, and first and second bio-compatible fixation elements attached to the first and second end regions of the tape respectively. Each bio-compatible fixation element has a tissue adherence property greater than that of the tape.

Claims

1. An implant for use in the treatment of stress urinary incontinence in a patient, comprising:

an implantable, elongated tape having a multiplicity of openings formed through the thickness thereof, the tape having a first end region and a second end region longitudinally opposite the first end region; and

first and second bio-compatible fixation elements attached to the first and second end regions of the tape respectively, each bio-compatible fixation element having a tissue adherence property greater than that of the tape, wherein the tape includes a top side and a bottom side, the top side have a first marking thereon and the bottom side having a second marking thereon, the second marking being different from the first marking to thereby distinguish the top side from the bottom side.

2. An implant for use in the treatment of stress urinary incontinence in a patient, comprising:

an implantable, elongated tape having a multiplicity of openings formed through the thickness thereof, the tape having a first end region and a second end region longitudinally opposite the first end region; and

first and second bio-compatible fixation elements attached to the first and second end regions of the tape respectively, each bio-compatible fixation element having a tissue adherence property greater than that of the tape wherein the tape includes a plurality of spaced apart filament tangles attached thereto.

3. A method of implanting an implant in a patient for the treatment of stress urinary incontinence, the method comprising the steps of:

providing an implant including an implantable, elongated tape portion having a multiplicity of openings formed through the thickness thereof, and having a first end region and a second end region longitudinally opposite the first end, and first and second bio-compatible fixation elements attached to the first and second end regions of the tape respectively, each bio-compatible fixation element having a stiffness and/or tissue adherence property greater than that of the tape;

making an incision in the vaginal wall of the patient;

inserting the first fixation element and attached tape through the incision and into connective tissue attached to the pubic bone to a first side of the patient'"'"'s uretha;

inserting the second fixation element and attached tape through the incision and into connective tissue attached to the pubic bone on the opposite side of the patient'"'"'s urethra such that the tape forms a loop partially around the urethra to provide support for the urethra; and

leaving the implant implanted in the body of the patient, wherein the first and second inserting steps further comprise inserting the first and second fixation elements respectively into connective tissue at the lower edge of the pubic bone.
