Abstract

A method and device for anchoring a length of self-retaining suture. The method of anchoring includes providing for an assembly having a length of self-retaining suture and a suture insertion device. The length of suture includes at least a portion of the length having a plurality of retainers thereon extending in a first direction. The insertion device has a length and a recess to receive a portion of the suture length. The method further includes placing a portion of the suture length in the recess and inserting the device into the body of a mammal until the recess reaches a predetermined location thereby forming an insertion pathway. The method further includes retrieving the insertion device from the body by moving the insertion device in a direction substantially opposed to the insertion pathway.

Claims

1. A method of supporting an object within the body of a mammal comprising the steps of:

providing a continuous length of suture where the ends of the suture are joined forming a loop, the loop having;

a first length of suture having an elongate first body, a plurality of first retainers projecting from the first body in a first direction, the first retainers being disposed on the periphery of the first body along at least a portion of the first length,

a second length having a plurality of second retainers projecting from the second body in a second direction, the second direction being opposite to the first direction, the second retainers being disposed on the periphery of the second body along at least a portion of the second length,

an intervening length located between the first and second lengths, whereby all of the first retainers and all of the second retainers face the intervening length, and

a diverging length where the first length and second lengths are joined and where the first retainers and second retainers diverge and face in opposing direction;

placing at least a portion of the diverging length of the continuous length of suture under an object within the body of a mammal to be supported;

inserting the suture into a section of tissue of a mammal at a point along the intervening section forming an insertion pathway;

whereby the object within the body of a mammal is supported;

wherein the suture is inserted into a section of tissue by means of a suture insertion device comprising a substantially rigid, elongate body having a first device end, a second device end and a device length; and

a recess proximate to the first device end to receive a cross section of suture, and wherein the suture insertion device further comprises a forwardly extending finger located at the rearward end of the recess for maintaining the suture within the recess during insertion.

2. The method of claim 1 wherein when the suture is inserted into the tissue of a mammal at a point along the intervening part, the retainers generally flex toward the tissue during insertion where damage to the tissue by the retainers is minimized, and the retainers generally resist movement when the suture section is pulled in a direction opposed to the insertion pathway.

3. The method of claim 1 wherein the suture insertion device further comprises a rearwardly extending finger extending over a portion of the recess from the first device end.

4. The method of claim 1 wherein at least a portion of the first device end is sharpened so as to pierce the surface of the tissue.

5. The method of claim 1 wherein at least a portion of the bottom side of the device length is sharpened so as to cut the tissue during insertion.

6. The method of claim 1 wherein the suture insertion device further comprising a gripping member located proximate to the second device end.

7. The method of claim 6 wherein the gripping member further comprises a suture recess for receiving a length of suture along the length of the gripping member.

8. The method of claim 1 wherein the suture insertion device comprises a needle.

9. A method of supporting an object within the body of a mammal comprising the steps of:

providing a continuous length of suture where the ends of the suture are joined forming a loop, the loop having;

a first length of suture having an elongate first body, a plurality of first retainers projecting from the first body in a first direction, the first retainers being disposed on the periphery of the first body along at least a portion of the first length,

a second length having a plurality of second retainers projecting from the second body in a second direction, the second direction being opposite to the first direction, the second retainers being disposed on the periphery of the second body along at least a portion of the second length,

an intervening length located between the first and second lengths, whereby all of the first retainers and all of the second retainers face the intervening length, and

a diverging length where the first length and second lengths are joined and where the first retainers and second retainers diverge and face in opposing direction;

placing at least a portion of the diverging length of the continuous length of suture under an object within the body of a mammal to be supported;

inserting the suture into a section of tissue of a mammal at a point along the intervening section forming an insertion pathway;

whereby the object within the body of a mammal is supported;

wherein the suture is inserted into a section of tissue by means of a suture insertion device comprising a substantially rigid, elongate body having a first device end, a second device end and a device length; and

a recess proximate to the first device end to receive a cross section of suture, and wherein the suture insertion device further comprises a rearwardly extending finger extending over a portion of the recess from the first device end.

10. The method of claim 9 wherein when the suture is inserted into the tissue of a mammal at a point along the intervening part, the retainers generally flex toward the tissue during insertion where damage to the tissue by the retainers is minimized, and the retainers generally resist movement when the suture section is pulled in a direction opposed to the insertion pathway.

11. The method of claim 9 wherein the suture insertion device further comprises a forwardly extending finger located at the rearward end of the recess for maintaining the suture within the recess during insertion.

12. The method of claim 9 wherein at least a portion of the first device end is sharpened so as to pierce the surface of the tissue.

13. The method of claim 9 wherein at least a portion of the bottom side of the device length is sharpened so as to cut the tissue during insertion.

14. The method of claim 9 wherein the suture insertion device further comprising a gripping member located proximate to the second device end.

15. The method of claim 14 wherein the gripping member further comprises a suture recess for receiving a length of suture along the length of the gripping member.

16. The method of claim 9 wherein the suture insertion device comprises a needle.
