Modular suture
View Patent ↗Sutures are provided having a first elongate body and a separate, second elongate body. The first elongate body includes a first connection structure and the second elongate body may include a second connection structure.
1. A suture comprising:
a first length of suture having proximal and distal portions and a first connection structure, wherein the first connection structure includes a cavity defined in the distal portion and at least a first recess spaced proximal of a distal end of the distal portion in communication with the cavity; and
a separate second length of suture selectively connectable to the first connection structure and including an extension and at least one projection extending radially outward from the extension, wherein the at least one projection is configured to extend into the at least first recess in the distal portion of the first length of suture when the extension is received within the cavity of the distal portion.
2. The suture according to claim 1 , wherein upon the receipt of the at least one projection through the at least one recess, separation of the second length of suture from the first length of suture is prevented.
3. The suture according to claim 1 , wherein the first or second length of suture comprises an end effector.
4. The suture according to claim 3 , wherein the end effector is selected from the group consisting of a loop and a knot.
5. The suture according to claim 1 , wherein first or second length of suture comprises a needle disposed at one end thereof.
6. The suture according to claim 1 , wherein the first and second length of suture each comprise a needle disposed at one end thereof.
7. The suture according to claim 1 , wherein the first or second length of suture further comprises barbs disposed on a length thereof.
8. The suture according to claim 1 , wherein the at least first recess includes a notch and the at least first projection includes a barb.
9. The suture according to claim 1 , wherein the at least first recess includes first and second notches and the at least first projection includes first and second barbs.
10. The suture according to claim 1 , wherein the at least first recess includes a slot and the at least first projection is configured to be received through the slot.
11. A suture comprising at least two separately connectable lengths of suture, wherein a first length of suture comprises an end portion including a first connection structure that is connectable to a second connection structure of a second length of suture, wherein the first connection structure defines a perforation and the second connection structure includes a pair of arms each having a bulbous end portion configured for reception within the perforation of the first connection.
12. The suture according to claim 11 , wherein the first length of suture comprises a first plurality of barbs.
13. The suture according to claim 12 , wherein the first plurality of barbs prevents suture reversal in a first direction.
14. The suture according to claim 11 , wherein the second length of suture comprises a second plurality of barbs.
15. The suture according to claim 14 , wherein the second plurality of barbs prevents suture reversal in a second direction.
16. The suture according to claim 11 , wherein the pair of arms is configured to flex away from each other to facilitate reception of the bulbous end portions within the perforation.
