Abstract

Various surgical introducer needle and anchor systems are provided. The systems can include an introducer needle and a tissue support implant or sling device. The implant device can include one or more anchoring devices. The introducer needle device can include a handle assembly and a needle assembly. The needle assembly can include a generally hollow needle, and a wire traversable therein. The wire can include a distal tip adapted to selectively retract or withdraw from the engaged anchoring device upon deployment of the anchor and/or implant.

Claims

1. A surgical needle device, comprising:

a needle including a lumen, a proximal portion, and a wire disposed in and traversable along at least a portion of the lumen; and

a handle assembly including at least one depressible actuator, and a body portion having a proximal portion and a distal portion, the distal portion of the body coupled to the proximal portion of the needle, and the at least one depressible actuator in operative communication with a portion of the wire and extending angularly from an outer surface of the body and generally toward the needle.

2. The device of claim 1, wherein a distal portion of the needle receives an anchor device.

3. The device of claim 2, wherein the anchor device includes one or more extending tines to facilitate soft tissue engagement.

4. The device of claim 1, wherein a distal portion of the needle includes a barb guard to abuttably receive an anchor device.

5. The device of claim 1, wherein the at least one depressible actuator includes first and second depressible actuators extending angularly from the outer surface of the body at an angle less than ninety degrees relative to a generally straight length of the needle.

6. The device of claim 1, wherein the distal portion of the needle includes a curved length.

7. A surgical needle device, comprising:

a needle including a generally straight length, a generally curved length, a lumen, a distal portion, and a wire extending through and traversable along at least a portion of the lumen; and

a handle assembly including a body, and first and second actuators operatively connected with the wire, the body having a distal end portion and a proximal end portion, wherein the generally straight length of the needle extends out from the distal end portion of the body and the first and second actuators angle out from the body generally toward the needle and are retractable a distance back into the distal end portion of the body.

8. The device of claim 7, wherein the distal portion of the needle receives an anchor device.

9. The device of claim 8, wherein the anchor device includes one or more extending tines to facilitate soft tissue engagement.

10. The device of claim 7, wherein the distal portion of the needle includes a barb guard to abuttably receive an anchor device.

11. The device of claim 7, wherein the first and second actuators angle out from the distal end portion of the body at an angle less than ninety degrees relative to the generally straight length of the needle.

12. A surgical implant system, comprising:

a sling implant having opposing end portions and a support portion, and at least one anchor provided at one of the opposing end portions;

an implant introducer tool including;

a needle having a generally straight length, a lumen, a distal portion, and a wire extending through and traversable along at least a portion of the lumen for selective engagement with the at least one anchor; and

a handle assembly having a body, and at least one depressible actuator operatively connected with the wire, the body having a distal end portion and a proximal end portion, wherein the generally straight length of the needle extends out from the distal end portion of the body and the at least one depressible actuator angles out from and is retractable a distance back into the distal end portion of the body.

13. The system of claim 12, wherein the at least one anchor includes one or more extending tines to facilitate soft tissue engagement.

14. The system of claim 13, wherein the distal portion of the needle includes a barb guard to abuttably receive the at least one anchor.

15. The system of claim 12, wherein the at least one depressible actuator includes first and second actuators angling out from the distal end portion of the body at an angle less than ninety degrees relative to the generally straight length of the needle.

16. The system of claim 12, wherein a portion of the needle includes a generally curved length.

17. The system of claim 12, wherein the at least one anchor includes an anchor device provided at each of the opposing end portions of the sling implant.

18. The system of claim 12, wherein the sling implant is constructed at least in part of a polymer mesh material.

19. The system of claim 12, wherein the distal portion of the needle includes a barb guard having an angled barb surface, and the at least one anchor has an angled anchor surface that abuttably seats with the angled barb surface.

20. The system of claim 12, wherein a distal tip of the wire extends through and out of the at least one anchor.
