Abstract

A prosthesis for repairing a hernia defect includes a patch body, a hoisting frame releasably attachable to the patch body, and a tether attached to the hoisting frame with a free end extendable through the thickness of the patch body and accessible from the side of the patch body opposite to where the hoisting frame is releasably attached. The patch body and/or the hoisting frame includes a self-expanding support member. The hoisting frame includes a frame body with an outer frame component and a force translation component for directing pulling forces on the tether across the frame body. The outer frame component has a loop configuration to generally follow the patch periphery with overlapping end portions or a gap between free ends thereof. The force translation component is separable into multiple segments to facilitate withdrawal of the hoisting frame through an opening when released from the patch.

First claim

What is claimed is:

1. A prosthesis for repairing a hernia defect, the prosthesis comprising:
a patch body having a periphery, a first axis and a second axis perpendicular to the first axis, the first axis and the second axis intersecting at approximately a center of the patch body, a first portion of the patch body on one side of the first axis and a second portion of the patch body on the other side of the first axis;
a self-expanding hoisting frame releasably attachable to the patch body to assist in spreading the patch body from a reduced configuration to an expanded configuration, the self-expanding hoisting frame including an outer frame component and an inner frame component configured to translate force, the outer frame component defining an open interior and the inner frame component extending through the open interior, the outer frame component including a first free end and a second free end, the outer frame component extending continuously about the open interior from the first free end to the second free end thereof; and
a tether attached to the inner frame component, a free end of the tether extendable away from the inner frame component and through the patch body when the hoisting frame is releasably attached to the patch body, a pulling force on the free end of the tether in an outward direction away from the patch body being directed by the inner frame component in the direction of the outer frame component when the patch body is in the expanded configuration;
wherein the patch body and the hoisting frame when releasably attached to the patch body are manipulable into the reduced configuration for insertion through an opening into a patient.

2. The prosthesis according to claim 1 , wherein the outer frame component is self-expanding.

3. The prosthesis according to claim 2 , wherein the inner frame component is non-self-expanding.

4. The prosthesis according to claim 2 , wherein the outer frame component includes a self-expanding support.

5. The prosthesis according to claim 1 , wherein the outer frame component has a configuration that generally follows the periphery of the patch body.

6. The prosthesis according to claim 5 , wherein the outer frame component is spaced inwardly of the periphery of the patch body.

7. The prosthesis according to claim 1 , wherein the first and second free ends of the outer frame component are spaced apart from each other to define a gap therebetween.

8. The prosthesis according to claim 7 , wherein the hoisting frame has a first axis and a second axis perpendicular to the first axis, the first and second axes of the hoisting frame intersecting at approximately a center of the hoisting frame, the gap being located entirely on one side of the first axis and along the second axis of the hoisting frame.

9. The prosthesis according to claim 8 , wherein the gap is centered on the second axis of the hoisting frame.

10. The prosthesis according to claim 8 , wherein the first and second free ends are located on opposite sides of the second axis of the hoisting frame.

11. The prosthesis according to claim 8 , wherein the inner frame component includes a central portion located at the center of the hoisting frame and a plurality of arms extending from the central portion to the outer frame component.

12. The prosthesis according to claim 11 , wherein the plurality of arms includes a first pair of arms located on a first side of the first axis of the hoisting frame and a second pair of arms located on a second side of the first axis of the hoisting frame, the gap located between the second pair of arms.

13. The prosthesis according to claim 12 , wherein the inner frame component is configured to be separated into a plurality of inner frame segments to facilitate withdrawal of the hoisting frame through the opening when the hoisting frame is released from the patch body.

14. The prosthesis according to claim 13 , wherein separation of the central portion causes the first pair of arms to separate from each other and the second pair of arms to separate from each other to facilitate withdrawal of the hoisting frame.

15. The prosthesis according to claim 13 , wherein the outer frame component is reconfigurable into an elongated frame component following separation of the central portion, the first and second free ends defining opposite ends of the elongated frame component.

16. The prosthesis according to claim 13 , wherein the central portion is configured to be separated in a direction along the second axis of the hoisting frame.

17. The prosthesis according to claim 13 , wherein the central portion includes a preformed separation region.

18. The prosthesis according to claim 1 , wherein the outer frame component includes a first end segment terminating at the first free end and a second end segment terminating at the second free end, the first end segment and the second end segment overlapping each other to define an overlap region therebetween.

19. The prosthesis according to claim 18 , wherein the first end segment and the second end segment are releasably coupled together at the overlap region.

20. The prosthesis according to claim 19 , wherein one of the first end segment and the second end segment includes a retainer configured to cooperate with the other of the first end segment and the second end segment to couple the first and second end segments to each other.

21. The prosthesis according to claim 19 , wherein one of the first end segment and the second end segment includes a pocket to releasably receive the other of the first end segment and the second end segment to couple the first and second end segments to each other.

22. The prosthesis according to claim 18 , wherein the outer frame component completely surrounds the open interior when the first end segment and the second end segment overlap each other.

23. The prosthesis according to claim 18 , wherein the hoisting frame has a first axis and a second axis perpendicular to the first axis, the first and second axes of the hoisting frame intersecting at approximately a center of the hoisting frame, the overlap region being located between the first axis and the second axis of the hoisting frame.

24. The prosthesis according to claim 18 , wherein the inner frame component includes a central portion located at the center of the hoisting frame and a plurality of arms extending from the central portion to the outer frame component.

25. The prosthesis according to claim 24 , wherein the central portion is configured to be separated to cause at least two of the arms to separate from each other to facilitate withdrawal of the hoisting frame.

26. The prosthesis according to claim 25 , wherein each of the plurality of arms includes a free end coupled together at the central portion.

27. The prosthesis according to claim 26 , wherein the free ends of the plurality of arms are coupled together with the tether.

28. The prosthesis according to claim 25 , wherein the hoisting frame is configured to be manipulated into an elongated configuration following separation of the central portion.

29. The prosthesis according to claim 24 , wherein the hoisting frame has a first axis and a second axis perpendicular to the first axis, the plurality of arms includes a first pair of arms located on a first side of the first axis of the hoisting frame and a second pair of arms lo
