Surgical articles and methods for treating pelvic conditions
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.

4. The medical apparatus of claim 3 , wherein the first fin of the base of the fixating tip includes a leading edge originating at the base at a first location and extending from the base towards the proximal end of the base to a point, the first fin of the base of the fixating tip including a trailing edge originating at the base at a second location and extending to the point.
5. The medical apparatus of claim 3 , wherein the first fin of the fixating tip and the second fin of the fixating tip extend in opposite directions.
6. The medical apparatus of claim 1 , wherein the end guard has a diameter larger than a diameter of a shaft of the needle, the diameter of the end guard being larger than a diameter of the protruding portion.
7. The medical apparatus of claim 1 , wherein the mesh implant is coupled to the fixating tip with a suture.
8. The medical apparatus of claim 1 , wherein the internal channel extends entirely through the base of the fixating tip.
9. The medical apparatus of claim 1 , wherein the second direction is opposite to the first direction.
10. A medical apparatus, comprising:
a handle;
a needle including a proximal end attached to the handle and a distal end portion, the distal end portion including a flared end guard extending out from a shaft of the needle, the flared end guard including a distal face, with a protruding portion extending from the distal face, the protruding portion having a diameter smaller than a diameter of the distal face, the protruding portion defining a bore; and
an anchor device including a base defining an internal channel along a longitudinal axis of the base, the base of the anchor device having a distal end, and a proximal end, the proximal end of the base defining an opening to the internal channel, the base including a first side portion defining a first fin extending in a first direction away from the longitudinal axis of the base, and a second side portion defining a second fin extending in a second direction away from the longitudinal axis of the base,
the anchor device configured to be removably coupled to the flared end guard, the internal channel configured to receive the protruding portion through the opening on the proximal end of the base of the anchor device such that the distal face of the flared end guard abuts the proximal end of the base of the anchor device.
11. The medical apparatus of claim 10 , wherein the first fin includes a leading edge originating at the base at a first location and extending from the base towards the proximal end of the base to a point, and a trailing edge originating at the base at a second location and extending to the point.
12. The medical apparatus of claim 11 , wherein the leading edge is a sharpened edge.
13. The medical apparatus of claim 11 , wherein the leading edge includes a curved portion.
14. The medical apparatus of claim 10 , further comprising:
an implant having a support portion, a first extension portion, and a second extension portion, the first extension portion being coupled to the anchor device.
15. The medical apparatus of claim 10 , wherein the flared end guard defines a longitudinal axis, a first side portion, and a second side portion, the first side portion of the flared end guard defining a first fin extending away from the longitudinal axis of the flared end guard, the second side portion of the flared end guard defining a second fin extending away from the longitudinal axis of the flared end guard.
16. The medical apparatus of claim 15 , wherein the first fin of the flared end guard and the second fin of the flared end guard extend in opposite directions.
17. A medical apparatus, comprising:
a handle;
a needle including a proximal end attached to the handle and a distal end portion, the distal end portion including an end guard, the end guard including a distal face, with a protruding portion extending from the distal face along a longitudinal axis of the needle, the protruding portion including a pin that has a smaller diameter than a diameter of the distal face,
the end guard including a first side portion defining a first fin extending in a first direction away from the longitudinal axis, the end guard including a second side portion defining a second fin extending in a second direction away from the longitudinal axis; and
a fixating tip including a base defining an internal channel along a central axis of the base, the base having a distal end, and a proximal end, the proximal end of the fixating tip defining an opening to the internal channel,
