Abstract

The guidance and positioning device may be a system for creating a passage in tissue, positioning fasteners or other implants, and tensioning an elongated fastening member, like a suture, thread, wire, or pin. In some embodiments, the device may allow for the implantation of multiple sutures and fasteners in tissue. A fastener may be positioned at the distal end of a flexible pushrod. The fastener may be connected with the pushrod or may be loosely fitted with the distal end of the pushrod. A suture may be looped through or connected with the fastener such that one, two, or more sections, legs, strands, or portions of the suture extend from the fastener.

First claim

What is claimed is:

1. A deformable fastener system comprising:
a flexible hollow fastener fabricated solely from a plurality of biocompatible fibers;
a suture extending through the hollow fastener such that two legs of the suture extend from the hollow fastener to enable a user to tension the suture, wherein at least a portion of the suture is fabricated with polyethylene; and
an introducer having a pushrod configured to engage the fastener and position the fastener relative to a body tissue, wherein the hollow fastener and suture are positioned on the distal end of the pushrod, and
wherein the hollow fastener is configured to deform from a first configuration to a second configuration to provide an anchor for the suture as the suture is tensioned relative to the body tissue; and
wherein the hollow fastener includes a polymeric material.

2. The system of claim 1 , wherein the suture includes at least a portion of polyester.

3. The system of claim 1 , wherein the hollow fastener is knotless.

4. The system of claim 1 , wherein the suture is positionable through proximal and distal portions of body tissue.

5. The system of claim 1 , wherein the pushrod is flexible.

6. The system of claim 1 , wherein the introducer has at least one of a linear configuration and a curved configuration.

7. The system of claim 1 , wherein the distal portion of the introducer is configured to penetrate an imperforate surface of the body.

8. A deformable fastener system comprising:
a suture;
a flexible hollow fastener fabricated solely from a plurality of fibers comprised of a biocompatible polymeric material, wherein at least a portion of the suture extends through the hollow fastener such that two legs of the suture extend from the hollow fastener to enable a user to tension the suture to deform the hollow fastener from a first configuration to a second configuration to anchor the suture within the body; and
an introducer with a pushrod configured to engage the fastener, wherein the hollow fastener and suture are positioned on the distal end of the pushrod.

9. The system of claim 8 , wherein the suture is at least one of braided and interlaced.

10. The system of claim 8 , wherein the suture includes polyethylene.

11. The system of claim 8 , wherein the suture includes at least a portion of polyester.

12. The system of claim 8 , wherein the pushrod is flexible.

13. The system of claim 8 , wherein the introducer has at least one of a linear configuration and a curved configuration.

14. A method of using a deformable fastener system, said method comprising:
inserting a deformable hollow fastener into a passage in a bone, the deformable hollow fastener being flexible and fabricated solely from a plurality of flexible biocompatible fibers, and having a suture extending through the deformable hollow fastener such that two legs of the suture extend from the deformable hollow fastener to enable a user to tension the suture, wherein the deformable hollow fastener and suture are positioned on the distal end of a pushrod during insertion;
tensioning the suture to anchor the deformable hollow fastener into the bone;
deforming the deformable hollow fastener from a first configuration to a second configuration in the bone; and
wherein inserting a deformable hollow fastener further comprises inserting a deformable hollow fastener that includes a polymeric material.

15. The method of claim 14 , wherein inserting a deformable hollow fastener having a suture further comprises inserting a deformable hollow fastener having a suture that is at least one of braided and interlaced.

16. The method of claim 14 , wherein inserting a deformable hollow fastener having a suture further comprises inserting a deformable hollow fastener having a suture that includes at least one of polyethylene and polyester.

17. The method of claim 14 , wherein inserting a deformable hollow fastener further comprises inserting a deformable hollow fastener with a pushrod that is flexible.

18. The method of claim 14 , wherein inserting a deformable hollow fastener further comprises inserting a deformable hollow fastener with an introducer that has at least one of a linear configuration and a curved configuration.

19. The system of claim 8 , wherein the hollow fastener is knotless.

20. The method of claim 14 , wherein inserting a deformable hollow fastener further comprises inserting a deformable hollow fastener that is knotless.
