13. A kit according to claim 1 further including a non-synthetic biomaterial for the different implant material.
14. A surgical kit for use in assembling an implant for treating incontinence, the kit comprising:
an elongate biocompatible synthetic material suitable for forming a first portion of the implant, the first portion having a distal end and an integration end, and
an implant assembly tool for substantially direct association with the synthetic material for holding the synthetic material while a different biocompatible implant material is attached to the integration end, wherein the implant assembly tool comprises a pair of jaws and a structured surface, and the implant assembly tool is connected to the synthetic material by interaction between the structured surface and the synthetic material, wherein the structured surface comprises hooks for a hook and loop type association between the implant assembly tool and the synthetic material.
15. A kit according to claim 14 wherein the implant assembly tool includes handle portions with structure for enhancing manual grasping of the implant assembly tool.
16. A kit according to claim 10 wherein the synthetic material is a non-absorbable material.
17. An assembly for use in constructing a composite sling for treating a patient's incontinence, the composite sling comprising:
a first segment comprising a synthetic material having a distal end and an attachment end;
a second segment comprising a synthetic material having a distal end and an attachment end;
an integrator for associating a biomaterial with the attachment ends of the first and second segments so that the biomaterial may be placed underneath the patient's urethra, said integrator comprising Y-shaped portions at the attachment ends of the first and second segments, and said Y-shaped portions including a pair of legs and a seam, and
wherein the first and second segments are sized and shaped to extend from a position substantially adjacent the patient's urethra to a position substantially adjacent the patient's rectus fascia so that the first and second segments and the biomaterial can provide a U-shaped sling extending from the patient's rectus fascia in the abdominal region, to a position below the patient's urethra, and back to the rectus fascia on an opposite side of the patient's urethral and
wherein the first and second segments include a tensioning filament for adjusting placement of the sling within the patient,
the tensioning filament being attached to the synthetic material at a location substantially adjacent, yet spaced from legs of the Y-shaped portions, and
wherein each of the first and second segments further include a removable loosening loop operatively associated with a tensioning filament, the removable loosening loop adapted to be cut and removed once the implant is properly tensioned, and
a tab associated with the loosening loop.
wherein the loosening loop includes a pair of knots so that when the loosening loop is cut, the loosening loop may be removed from the segment without a knot passing through the segment.
18. An assembly according to claim 17 wherein the integrator comprises strengtheners.
19. An assembly according to claim 18 wherein the strengtheners comprise silicone integrated into the first and second segments.
20. An assembly according to claim 18 wherein the strengtheners comprise suture anchors for the biomaterial.
21. An assembly according to claim 17 wherein the synthetic material is a non-absorbable material.
22. An assembly according to claim 17 wherein the loosening loop is looped around the seam of the Y-shaped portion to resist damage to the biomaterial and the attachment between the biomaterial and the synthetic material during adjustment of the placement of the sling within the patient.
23. An assembly according to claim 17 further including biomaterial comprising porcine tissue.
24. A sling assembly tool/implant combination, said combination comprising:
a sling assembly tool for assembling an implant from a first biocompatible material and second biocompatible material that is different from the first material, the tool comprising:
holders for retaining the first and second biocompatible materials in a substantially flat condition while the first and second biocompatible materials are attached, said holders comprising a pair of jaws, said jaws being movable between an open position and a closed position, and
a passageway for passage of a joiner for attaching the first material to the second material, said combination further comprising
a first biocompatible material comprising a Y-shaped structure including a pair of leg portions and a seam,
wherein each jaw of said sling assembly tool is connected to a leg portion of said biocompatible material,
wherein said jaws are movable between an open position with the leg portions spaced apart to receive a second biocompatible material therebetween, and a closed position with the leg portions spaced closer together than in the open position.
25. A sling assembly tool/implant combination according to claim 24 wherein the seam has an axis, and
the leg portions have ends, and the jaws are mounted to pivot about an axis that is substantially parallel or colinear with the axis of the seam so that the ends of the leg portions remain substantially parallel during movement between the open and closed positions.
