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 system, comprising:

an anchor device including a first tine and a second tine;

a needle including a proximal end portion and a distal end portion, the first tine and the second tine of the anchor device abuttably seatable against the distal end portion, the needle defining a lumen; and

a handle assembly including a first actuator and a second actuator, the first actuator and the second actuator being coupled by a base portion, an alignment member disposed inside of the handle assembly, and a body portion having a proximal portion and a distal portion, the distal portion of the body portion coupled to the proximal end portion of the needle, the needle being configured to engage the alignment member to align and secure the proximal end of the needle within the handle assembly;

a connecting member having a proximal end and a distal end, the proximal end of the connecting member coupled to the base portion, the distal end of the connecting member configured to extend out of the lumen at the distal end portion of the needle in response to the at least one actuator being within an extended position, the anchor device defining an anchor bore configured to receive and engage with the distal end of the connecting member,

wherein the first actuator and the second actuator are configured to proximally retract along the body portion causing the connecting member to retract and the distal end of the connecting member to withdraw from the anchor bore.

2. The system of claim 1, wherein the distal end portion of the needle includes a barb guard.

3. The system of claim 1, wherein the first and second actuators extend out angularly from an outer surface of the body portion of the handle assembly.

4. The system of claim 1, wherein the distal end portion of the needle includes a curved length.

5. The system of claim 1, wherein the connecting member includes a wire.

6. The system of claim 5, wherein the anchor bore of the anchor device is engageable with a distal end portion of the wire.

7. The system of claim 1, further including a sling implant, with the anchor device provided with the sling implant.

8. The system of claim 1, wherein the distal end portion of the needle includes a barb guard, the barb guard including a coupling portion, a first extending member, and a second extending member, the first extending member having a first terminal end coupled to the coupling portion and a second terminal end configured to engage with a terminal end of the first tine.

9. The system of claim 1, wherein each of the first actuator and the second actuator includes a body portion to define a gap therebetween.

10. The system of claim 9, wherein the alignment member is configured to be disposed within the gap.

11. The system of claim 1, wherein the alignment member includes a H-shaped block.

12. A surgical needle system, comprising:

an anchor device including a first tine and a second tine;

a needle including a proximal end portion and a distal end portion, the distal end portion including a barb guard, the barb guard including a first flared extension and a second flared extension, wherein a terminal end of the first flared extension and a terminal end of the second flared extension is configured to contact a terminal end of the first tine and a terminal end of the second tine, respectively;

a handle assembly including at least one actuator, and a body portion having a proximal portion and a distal portion, the distal portion of the body portion coupled to the proximal end portion of the needle; and

a wire having a proximal end and a distal end, the proximal end of the wire coupled to the at least one actuator, the distal end of the wire configured to extend out of a lumen at the distal end portion of the needle in response to the at least one actuator being within an extended position, the anchor device defining an anchor bore configured to receive and engage with the distal end of the wire,

wherein the at least one actuator is configured to proximally retract along the body portion causing the wire to retract and the distal end of the wire to withdraw from the anchor bore,

wherein the handle assembly further includes a spring biasing the wire outwardly.

13. The system of claim 12, wherein the at least one actuator includes a first actuator and a second actuator.

14. The system of claim 13, wherein the first and second actuators extend out angularly from an outer surface of the body portion of the handle.

15. The system of claim 12, wherein the distal end portion of the needle includes a curved length.

16. The system of claim 12, wherein the anchor bore of the anchor device is engageable with a distal end portion of the wire.

17. The system of claim 12, further including a sling implant.

18. The system of claim 17, wherein the anchor device is provided with the sling implant.

19. A surgical needle system, comprising:

an anchor device including a first tine and a second tine;

a needle including a proximal end portion and a distal end portion, the first tine and the second tine of the anchor device abuttably seatable against the distal end portion, the needle defining a lumen; and

a handle assembly including at least one actuator, and a body portion having a proximal portion and a distal portion, the distal portion of the body portion coupled to the proximal end portion of the needle;

a wire having a proximal end and a distal end, the proximal end of the wire coupled to the at least one actuator, the distal end of the wire configured to extend out of the lumen at the distal end portion of the needle in response to the at least one actuator being within an extended position, the anchor device defining an anchor bore configured to receive and engage with the distal end of the wire,

wherein the at least one actuator is configured to proximally retract along the body portion causing the wire to retract and the distal end of the wire to withdraw from the anchor bore, and

wherein the handle assembly includes a spring biasing the wire outwardly.
