Abstract

An implant, insertion tool, combinations, and associated methods, that involve placement of a self-fixating tip at tissue of the pelvic region, wherein an insertion tool includes one or more of an aperture for engaging a guide and an extension guard, the method optionally allowing for initial placement of a self-fixating tip at tissue of the pelvic region and adjustment of the location of the self-fixating tip. A threading guide is provided to assist in threading the guide through the aperture. An anchor also provided to with a retaining member to retain the anchor in tissue.

Claims

1. A system to re-thread a guide and tool comprising:

an anchor for inserting into tissue;

a guide having a first end connected to a portion of the anchor and a free second end;

a handle and a needle extending from the handle, the needle comprising a proximal end attached to the handle and a distal end that includes a needle tip, an aperture, and a tapered portion such that a diameter of the needle tip is smaller than a diameter of the distal end proximate the needle tip;

a threading guide being removably connectable to the needle tip to aid in threading the free end of the guide into the aperture, the threading guide having a funneling portion, an axial passageway in registration with the aperture, and a needle engagement portion smaller in diameter than the funneling portion and adapted to fit around the needle tip up to the tapered portion such that the needle engagement portion abuttably stops against the tapered portion of the needle tip and the funneling portion flares out from the needle tip; and

an attachment member attached to and extending away from the threading guide, the attachment member having a tether connected to the threading guide and a coupler connected to an end of the tether.

2. The system of claim 1 wherein the axial passageway tapers from the funneling portion toward the needle engagement portion.

3. The system of claim 1 wherein the aperture includes a bore having a diameter in the range from 0.1 to 2 millimeters.

4. The system of claim 1 wherein the coupler comprises a ring for threading over a portion of the needle.

5. The system of claim 1 wherein the anchor comprises an anchor tip for inserting into tissue and a retaining member for retaining the anchor in tissue.

6. The system of claim 5 further comprising concentric ridges about the anchor tip to aid in resisting pullout of the anchor.

7. The system of claim 5 wherein the retaining member comprises a lattice framework having a free end that flares away from a central axis of the anchor to aid in resisting pullout of the anchor.
