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 assembly including;

a generally stationary needle having a lumen defined therethrough;

a wire having a distal tip portion, with the wire adapted to traverse along at least a portion of the needle lumen; and

a handle assembly including at least one actuator and a biasing member, with the at least one actuator being operatively coupled with the wire and the biasing member such that the biasing member biases the distal tip portion of the wire into an extended engagement position a distance outside of the needle lumen, with the distal tip portion being retractable upon activation of the at least one actuator.

2. The device of claim 1, wherein the distal tip portion is adapted to receive an anchor device having a bore therethrough such that the distal tip portion extends through and out the bore when the distal tip portion is in the extended engagement position.

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

4. The device of claim 2, further including a sling implant coupled with the anchor device.

5. The device of claim 4, wherein the sling implant is constructed of a compatible mesh material.

6. The device of claim 1, wherein the at least one actuator include two sliding actuators operatively coupled with the biasing member and the wire.

7. The device of claim 1, further including an anchor device, and wherein the needle includes a distal end including a barb guard adapted to abutably receive at least a portion of the anchor device.

8. The device of claim 1, further including a lock-out assembly in operative communication with the distal tip portion of the wire, the lock-out assembly including a body portion having at least one extending wing member selectively engageable with a portion of the handle assembly, and an abutment feature adapted to receive at least a portion of the body portion, such that the distal tip portion of the wire resists back travel within the needle lumen.

9. The device of claim 8, wherein the at least one actuator is in operative communication with the abutment feature such that movement of the at least one actuator causes the abutment feature to abut against the at least one extending wing member to disengage the at least one extending wing member from the handle assembly such that the distal tip portion of the wire can retract within the needle lumen.

10. A surgical needle system, comprising:

a tissue anchor having one or more extending tines;

a needle assembly including;

a needle having a lumen defined therethrough;

a wire having a distal tip portion, with the wire adapted to traverse along at least a portion of the needle lumen; and

a handle assembly including at a slider actuator and a biasing member, with the slider actuator being operatively coupled with the wire and the biasing member such that the biasing member biases the distal tip portion of the wire a distance outside of the needle lumen to facilitate engagement with the tissue anchor, with the distal tip portion being retractable upon activation of the slider actuator to disengage the distal tip portion from the tissue anchor.

11. The system of claim 10, further including a sling implant coupled with the tissue anchor.

12. The system of claim 11, wherein the sling implant is constructed of a compatible mesh material.

13. The system of claim 10, wherein the needle includes a distal end having a barb guard adapted to abutably receive at least a portion of the tissue anchor.

14. The system of claim 10, further including a lock-out assembly in operative communication with the distal tip portion of the wire, the lock-out assembly including a body portion having at least one extending wing member selectively engageable with a portion of the handle assembly, and an abutment feature adapted to confront at least a portion of the at least one extending wing member, such that the distal tip portion of the wire resists back travel within the needle lumen.

15. The system of claim 14, wherein the slider actuator is in operative communication with the abutment feature such that movement of the slider actuator causes the abutment feature to abut against the at least one extending wing member to disengage the at least one extending wing member from the handle assembly such that the distal tip portion of the wire can retract within the needle lumen.

16. The system of claim 14, wherein a proximal base of the slider actuator is housed within the handle assembly, and the abutment feature is at least partially defined within the proximal base of the slider actuator.

17. The system of claim 10, wherein a proximal portion of the needle is securely housed within the handle assembly such that the needle is substantially stationary.

18. The system of claim 10, further including means for selectively attaching and detaching the tissue anchor from the distal tip portion.

19. A method of using a surgical needle device, comprising:

providing a tissue anchor having one or more extending tines;

providing a needle device having a needle assembly and a handle assembly, with the needle assembly including a generally hollow needle and a wire, the wire adapted to traverse within at least a portion of the generally hollow needle, wherein the handle assembly includes a slider actuator in operative communication with the wire and a biasing member adapted to bias a distal tip of the wire into an extended position outside of the generally hollow needle;

securing the tissue anchor to the distal tip of the wire when the distal tip is in the extended position;

introducing at least the distal tip and secured tissue anchor into the pelvic region of a patient;

engaging the tissue anchor into tissue within the pelvic region of the patient; and

actuating the slider actuator of the handle assembly to retract the distal tip of the wire such that the distal tip disengages from the tissue anchor.

20. The method of claim 19, wherein providing the tissue anchor includes providing the tissue anchor with a mesh implant coupled to the tissue anchor, such that the mesh implant is adapted to support tissue within the pelvic region of the patient.

21. The method of claim 19, wherein providing the handle assembly includes providing a lock-out assembly in operative communication with the distal tip of the wire, the lock-out assembly including a body portion having at least one extending wing member selectively engageable with a portion of the handle assembly, and an abutment feature adapted to confront the at least one extending wing member, such that the distal tip of the wire resists back travel within the generally hollow needle.

22. The method of claim 21, wherein providing the slider actuator further includes providing the lock-out assembly in operative communication with the slider actuator such that movement of the slider actuator causes the abutment feature to abut against the at least one extending wing member to disengage the at least one extending wing member from the handle assembly such that the distal tip of the wire can retract within the generally hollow needle.
