Surgical implant system and method
An implant and suture locking system is provided. The implant can include a lateral or distal anchor, and a medial or proximal anchor. One or more suture loops can extend between and operatively connect the anchors. A medial suture loop can extend through apertures in the medial anchor to provide efficient and easily adjustable tensioning and suture locking for the implant.

the suture extending through to facilitate selective locking adjustment of the medial anchor in position upon deployment.
2. The system of claim 1 , wherein the medial anchor includes a third aperture.
3. The system of claim 1 , wherein the suture forms a lateral suture loop and the at least a portion of the third portion of the suture is configured to be disposed within the delivery device directly adjacent the sidewall of the delivery device such that the at least a portion of the third portion of the suture is disposed directly between the sidewall of the delivery device and the lateral anchor.
4. The system of claim 1 , wherein the suture includes a tensioning suture length and an adjustment suture length extending out from a bottom surface of the medial anchor.
5. The system of claim 4 , wherein the adjustment suture length passes through and is trapped within the tensioning suture length.
6. The system of claim 5 , wherein the tensioning suture length includes the knot, the knot being disposed proximate the bottom surface of the medial anchor.
7. The system of claim 1 , wherein the medial anchor is adapted for engagement with a perineal membrane.
8. The system of claim 1 , wherein the lateral anchor is adapted for engagement with an obturator foramen.
9. The system of claim 1 , wherein the suture has a first terminal end and a second terminal end.
10. The system of claim 1 , wherein the body portion of the lateral anchor includes a first end portion and a second end portion, the first extending member is disposed between the first end portion and the first aperture, the second extending member is disposed between the second end portion and the second aperture.
11. The system of claim 1 , wherein the knot is a first knot, the suture including a second knot, the second knot being disposed between the medial anchor and the lateral anchor.
12. The system of claim 1 , wherein the first extending member, the first aperture, the second aperture, and the second extending member are aligned.
13. A surgical implant system, comprising:
an implant device having a medial anchor, a distal anchor, and at least one suture operatively connecting the medial anchor and the distal anchor, the at least one suture includes an elastomeric material and extends between the medial anchor and the distal anchor, the distal anchor including a body portion, a first aperture, and a second aperture such that a suture portion of the at least one suture extends through the first aperture, extends through the second aperture towards the medial anchor, and extends to a location between an end of a first extending member of the distal anchor and an end of a second extending member of the distal anchor, the first aperture being disposed between the second aperture and the first extending member, the second aperture being disposed between the first aperture and the second extending member, the first extending member having a first portion and a second portion defining a space devoid of material between the first portion and the second portion,
the medial anchor includes a first surface portion and a second surface portion opposite the first surface portion, the first surface portion including a raised portion extending from the first surface portion to at least partially cover a knot of the at least one suture,
the at least one suture extending through one or more apertures of the medial anchor to facilitate selective locking adjustment of the medial anchor in position upon deployment, a portion of the suture extending from the one or more apertures and being disposed between the end of the first extending member and the end of the second extending member; and
a delivery tool having a handle portion and a needle portion, the needle portion being configured to move with respect to the handle portion such that a first portion of the needle portion is disposed within the handle portion in a first configuration and the first portion of the needle portion is disposed outside of the handle portion in a second configuration, the delivery tool being adapted to receive the extending member of the distal anchor and at least a portion of the suture such that the at least a portion of the suture is disposed within a slot defined by the needle portion of the delivery tool and such that the distal anchor is disposed between the at least a portion of the suture that is disposed within the slot and an opening of the slot, at least a portion of the suture being configured to be disposed within the delivery device adjacent a sidewall of the delivery device such that the at least a portion of the suture is disposed between the sidewall of the delivery device and the distal anchor.
14. The system of claim 13 , wherein the at least one suture includes a medial suture loop including a suture pair having first and second suture members.
15. The system of claim 14 , wherein the one or more apertures in the medial anchor includes a first aperture to receive the suture.
