Abstract

An example implant delivery system is disclosed. The example implant delivery system includes a delivery shaft including a proximal portion, a distal portion and a lumen extending therebetween. The delivery system also includes a frame detachably coupled to the distal portion of the delivery shaft and a tack member coupled to the frame.

First claim

What is claimed is:

1. An implant delivery system, the implant delivery system comprising:
a delivery shaft including a proximal portion, a distal portion and a lumen extending there between;
a frame detachably coupled to the distal portion of the delivery shaft;
a tack member coupled to the frame; and
a sheath having a lumen, wherein the delivery shaft and the frame are slidably disposed within the lumen of the sheath;
wherein the sheath constrains the frame in a contracted configuration within the lumen of the sheath.

2. The implant delivery system of claim 1 , further comprising a tether member coupled to a proximal portion of the tack member.

3. The implant delivery system of claim 2 , wherein the tether member extends within the lumen of the delivery shaft.

4. The implant delivery system of claim 1 , wherein the frame includes a body portion and a plurality of attachment arms extending away from the body portion.

5. The implant delivery system of claim 2 , wherein the tack member extends through an aperture in the body portion of the frame.

6. The implant delivery system of claim 5 , wherein a distal end portion of the tack member is configured to engage with a bone.

7. The implant delivery system of claim 6 , wherein retraction of the tether member is designed to disengage the tack member from a bone.

8. The implant delivery system of claim 7 , wherein the distal end portion of the tack member includes a tapered region.

9. The implant delivery system of claim 2 , wherein a proximal end portion of the tack member includes a bore extending along a longitudinal axis of the tack member.

10. The implant delivery system of claim 9 , wherein a distal end portion of the tether member is secured within the bore of the tack member.

11. The implant delivery system of claim 4 , wherein the plurality of attachment arms are configured to be attached to an implant.

12. The implant delivery system of claim 1 , wherein the frame is configured to detach from the delivery shaft in vivo.

13. The implant of claim 2 , wherein the tether is directly coupled to the frame.

14. The implant of claim 2 , wherein the tether is indirectly coupled to the frame via a connection member.

15. The implant delivery system of any one of claim 14 , wherein the frame further comprises a first aperture configured to couple with the connection member.

16. An implant delivery system, the implant delivery system comprising:
a delivery shaft including a proximal portion, a distal portion and a lumen extending therebetween;
a frame detachably coupled to the distal portion of the delivery shaft;
a tack member coupled to the frame;
a tether member coupled to a proximal portion of the tack member;

wherein the tether member is indirectly coupled to the frame via a connection member; and
a sheath having a lumen, wherein the delivery shaft and the frame are slidably disposed within the lumen of the sheath;
wherein the sheath constrains the frame in a contracted configuration within the lumen of the sheath.

17. The implant delivery system of claim 16 , wherein the tether member extends within the lumen of the delivery shaft.

18. The implant delivery system of claim 16 , wherein the frame includes a body portion and a plurality of attachment arms extending away from the body portion.

19. The implant delivery system of claim 18 , wherein the tack member extends through an aperture in the body portion of the frame.

20. The implant delivery system of claim 19 , wherein a distal end portion of the tack member is configured to engage with a bone.

21. The implant delivery system of claim 20 , wherein retraction of the tether member is designed to disengage the tack member from a bone.

22. The implant delivery system of claim 20 , wherein the distal end portion of the tack member includes a tapered region.

23. The implant delivery system of claim 16 , wherein a proximal end portion of the tack member includes a bore extending along a longitudinal axis of the tack member.

24. The implant delivery system of claim 23 , wherein a distal end portion of the tether member is secured within the bore of the tack member.

25. The implant delivery system of claim 18 , wherein the plurality of attachment arms are configured to be attached to an implant.

26. The implant delivery system of claim 16 , wherein the frame is configured to detach from the delivery shaft in vivo.

27. The implant delivery system of claim 16 , wherein the frame further comprises a first aperture configured to couple with the connection member.

28. The implant delivery system of claim 16 , wherein the connection member includes a first profile and wherein the lumen of the delivery shaft includes a second profile, and wherein the first profile is configured to mate with the second profile.

29. The implant delivery system of claim 28 , wherein the connection member engages with the distal portion of the delivery shaft such that manipulation of the delivery shaft causes manipulation of the connection member, wherein the connection member is configured to disengage from the delivery shaft, and wherein the connection member is configured to remain engaged to the frame after disengaging from the delivery shaft.

30. The implant delivery system of claim 16 , wherein the tack member is stationary with respect to the connection member.

31. The implant delivery system of claim 16 , wherein the tack member can translate with respect to the connection member.

32. The implant delivery system of claim 16 , wherein the tack member includes a shaft having a circumferential surface and one or more protrusions extending radially away from the circumferential surface.

33. The implant delivery system of claim 32 , wherein the one or more protrusions are configured to anchor the tack member beneath a layer of bone.

34. The implant delivery system of claim 32 , wherein the one or more protrusions are spaced away from each other along the shaft.

35. The implant delivery system of claim 16 , wherein the tack member includes a shaft formed from a first material and one or more fixation members disposed along the shaft, wherein the one or more fixation members are formed from a second material different from the first material.

36. The implant delivery system of claim 35 , wherein the one or more fixation members extend radially away from a circumferential surface of the shaft.

37. The implant delivery system of claim 16 , wherein the tether member extends within the lumen of the delivery shaft while the delivery shaft is attached to the frame, and wherein the tether member remains connected to the frame when the delivery shaft is detached from the frame.

38. The implant delivery system of claim 16 , wherein manipulation of the delivery shaft relative to the sheath causes the frame to be advanced out of the lumen of the sheath such that the frame assumes an expanded configuration.

39. The implant delivery system of claim 1 , wherein manipulation of the delivery shaft relative to the sheath causes the frame to be advanced out of the lumen of the sheath such that the frame assumes an expanded configuration.
