Closure device and method for tissue repair
First Claim
1. A suture anchor assembly comprising:
- a first anchor comprising a rounded bottom surface, a protrusion extending from the bottom surface, and openings;
a second anchor having a rounded bottom surface, a protrusion extending from the bottom surface, and openings; and
suture connecting the first and second anchors, the suture extending through the openings of the first anchor to fix the suture to the first anchor and a free end of the suture extending through the openings of to the second anchor such that pulling on the free end of the suture shortens a length of the suture between the first and second anchors, the coupling of the suture to the openings of the second anchor forming an one way knot to resist lengthening of the length of suture between the first and second anchors.

Abstract
A method of closing a tissue wound includes providing a wound closure device having a first anchor, a second anchor, and a flexible member movably attached to the second anchor, positioning the first anchor against tissue, passing the flexible member across the wound, positioning the second anchor against tissue, and pulling on a free end of the flexible member to shorten a length of the flexible member between the first and second anchors, thereby closing the wound. A wound closure device includes a first anchor, a second anchor; and a flexible member connecting the first anchor to the second anchor, the flexible member being movably attached to the second anchor, such that pulling on a free end of the flexible member shortens a length of the flexible member between the first and second anchors.

2. A surgical device comprising:
-
a needle having a wall defining a lumen with a longitudinal channel, the needle having a beveled tip and the wall defining a longitudinal slot therethrough; a handle coupled to the needle; a pusher positioned within the lumen and actuatable at the handle; and an implant including an elongate first retainer positioned within the longitudinal channel and including a protrusion extending through the longitudinal slot in the wall of the needle such that pulling on the delivery device after advancement of the delivery device through tissue causes the first retainer to be deployed from the needle by interaction of the protrusion and the tissue, the protrusion including openings; an elongate second retainer positioned within the longitudinal channel proximally of the first retainer and including a protrusion extending from a bottom surface of the retainer, the protrusion including openings, the pusher being arranged to advance the second retainer distally toward the needle tip; and suture extending through the openings and connecting the first and second retainers, the suture being fixed to the first retainer and movably coupled to the second retainer such that pulling on the suture shortens a length of the suture between the first and second retainers, the coupling of the suture to the second retainer acting to resist lengthening of the length of suture between the first and second retainers. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)

10. A suture anchor assembly comprising:
-
a first anchor comprising a rounded bottom surface, a rigid protrusion extending from the bottom surface, and openings; a second anchor having a rounded bottom surface, a rigid protrusion extending from the bottom surface, and openings; and suture connecting the first and second anchors, the suture extending through the openings of the first anchor to fix the suture to the first anchor and a free end of the suture extending through the openings of to the second anchor such that pulling on the free end of the suture shortens a length of the suture between the first and second anchors, the coupling of the suture to the openings of the second anchor forming an one way knot acting to resist lengthening of the length of suture between the first and second anchors.

11. A suture anchor assembly comprising:
-
a first anchor comprising a rounded bottom surface, a protrusion extending only from the bottom surface, and openings; a second anchor having a rounded bottom surface, a protrusion extending only from the bottom surface, and openings; and suture connecting the first and second anchors, the suture extending through the openings of the first anchor to fix the suture to the first anchor and a free end of the suture extending through the openings of to the second anchor such that pulling on the free end of the suture shortens a length of the suture between the first and second anchors, the coupling of the suture to the openings of the second anchor forming an one way knot acting to resist lengthening of the length of suture between the first and second anchors.

12. A suture anchor assembly comprising:
-
a first anchor comprising a rounded bottom surface, a protrusion extending from the bottom surface and extending an entire length of the bottom surface, and openings; a second anchor having a rounded bottom surface, a protrusion extending from the bottom surface and extending an entire length of the bottom surface, and openings; and suture connecting the first and second anchors, the suture extending through the openings of the first anchor to fix the suture to the first anchor and a free end of the suture extending through the openings of to the second anchor such that pulling on the free end of the suture shortens a length of the suture between the first and second anchors, the coupling of the suture to the openings of the second anchor forming an one way knot acting to resist lengthening of the length of suture between the first and second anchors.
