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 therebetween;
a tether extending within the lumen of the delivery shaft, the tether including proximal end and a distal end; and
a tack coupled to the tether, wherein the tack includes a central longitudinal axis, a distal end region and a proximal end region, the proximal end region having an inwardly extending bore extending along the longitudinal axis, the inwardly extending bore configured to accept the distal end of the tether;
wherein the tack includes an inner surface defining the inwardly extending bore, and wherein the distal end of the tether is fixedly attached to the inner surface of the tack.

2. The implant delivery system of claim 1 , wherein the distal end of the tether is attached to the inner surface of the tack by at least one of welding, gluing or crimping.

3. The implant delivery system of claim 1 , wherein the inwardly extending bore includes a first shape and wherein the distal end of the tether includes a second shape designed to mate with the first shape of the inwardly extending bore.

4. The implant delivery system of claim 3 , wherein the inwardly extending bore is cylindrically-shaped.

5. The implant delivery system of claim 1 , wherein the distal end region of the tack includes a shaft extending along the longitudinal axis and a conical tip positioned at the distal end of the shaft of the tack, and wherein the conical tip tapers from an outer surface of the shaft of the tack toward the central longitudinal axis.

6. The implant delivery system of claim 5 , wherein the tack includes a first lobe disposed along the shaft of the tack, and wherein the first lobe extends radially outward a first distance from the outer surface of the shaft of the tack.

7. The implant delivery system of claim 6 , wherein the first lobe extends continuously around the circumference of the shaft of the tack.

8. The implant delivery system of claim 6 , wherein the first distance that the first lobe extends radially outward from the outer surface of the shaft of the tack corresponds to a force required to remove the tack from a bone.

9. The implant delivery system of claim 6 , further comprising a second lobe disposed along the shaft of the tack, and wherein the second lobe extends radially outward a second distance from the outer surface of the shaft of the tack.

10. The implant delivery system of claim 9 , wherein the second lobe is spaced away from the first lobe longitudinally along the shaft of the tack.

11. The implant delivery system of claim 9 , wherein the first lobe and the second lobe are positioned adjacent to one another along the shaft of the tack.

12. The implant delivery system of claim 9 , wherein the first distance which the first lobe extends radially away from the outer surface of the shaft of the tack is equal to the second distance the second lobe extends radially away from the outer surface of the shaft of the tack.

13. The implant delivery system of claim 9 , wherein the first distance which the first lobe extends radially away from the outer surface of the shaft of the tack is greater than the second distance the second lobe extends radially away from the outer surface of the shaft of the tack.

14. The implant delivery system of claim 1 , further comprising an expandable frame detachably coupled to the delivery shaft, wherein the tack is secured to the frame.

15. 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 tether extending within the lumen of the delivery shaft, the tether including proximal end and a distal end; and
a tack coupled to both the tether and the frame, wherein the tack includes a central longitudinal axis, a distal end region and a proximal end region, the proximal end region having an inwardly extending bore extending along the longitudinal axis, the inwardly extending bore configured to accept the distal end of the tether;
wherein the tack includes an inner surface defining the inwardly extending bore, and wherein the distal end of the tether is fixedly attached to the inner surface of the tack.

16. The implant delivery system of claim 15 , wherein the distal end of the tack includes a shaft extending along the longitudinal axis, wherein the shaft of the tack includes an outer surface, a first lobe extending radially away from the outer surface of the shaft of the tack and a second lobe extending radially away from the outer surface of the shaft of the tack.

17. The implant delivery system of claim 16 , wherein the second lobe is spaced away from the first lobe longitudinally along the shaft of the tack.

18. 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; and
a tether extending within the lumen of the delivery shaft, the tether including a proximal end and a distal end, wherein the distal end of the tether is fixed to a proximal end of a tack member;
wherein the tack includes a first lobe extending radially outward form an outer surface of a shaft portion of the tack a first distance, and wherein the distance which the first lobe extends radially away from the outer surface of the shaft portion of the tack corresponds to a force required to remove the tack from a bone.
