Knotted suture end effector
A suture including a knotted end effector is provided. The suture includes a body portion defining a longitudinal axis and an end effector formed from the body portion. The end effector includes first and second extensions which extend outwardly from the longitudinal axis in opposite directions when the end effector is in a permanent configuration. The extensions of the end effector extend substantially along the longitudinal axis when the end effector is in a temporary position. In embodiments, at least a portion of the end effector includes a shape memory material.
1. A suture comprising:
an elongate body; and
an end effector formed from the elongate body, the end effector including
a first extension including a first plurality of throws formed about a first loop and a second loop formed about the first plurality of throws; and
a second extension including a second plurality of throws formed about the first loop and a third loop formed about the second plurality of throws.
2. The suture of claim 1 , wherein the first extension includes three (3) throws.
3. The suture of claim 1 , wherein the second extension includes three (3) throws.
4. The suture of claim 1 , wherein the end effector defines a substantially T-shape.
5. The suture of claim 1 , wherein the end effector is formed on a distal end of the elongate body.
6. The suture of claim 1 , wherein the end effector is fixed relative to an end of the elongate body.
7. The suture of claim 1 , wherein the end effector is formed from a single continuous length of the elongate body.
8. The suture of claim 1 , wherein each of the throws defines a central axis that is perpendicular to the longitudinal axis of the body portion.
9. The suture of claim 1 , wherein the number of the first plurality of throws equals the number of the second plurality of throws.
10. The suture of claim 1 , wherein the number of the first plurality of throws is not equal to the number of the second plurality of throws.
