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.

Claims

1-83. -83. (canceled)

84. A suture anchor assembly comprising:

an anchor comprising;

a top surface and an opposing bottom surface;

an elongated channel recessed into the bottom surface; and

a first passageway and a spaced apart second passageway extending from the top surface to the channel;

a suture comprising a proximal end and an opposing distal end, a portion of the suture between the proximal end and the distal end being formed into a loop, the loop being at least partially passed through the first passageway, at least one of the proximal end or the distal end of the suture being passed through the second passageway and then through the loop such that pulling on the proximal end or the distal end of the suture that is passed through the loop causes the suture to selectively lock against the anchor.

85. A suture anchor assembly as recited in claim 84, wherein the anchor further comprises a third passageway, wherein the proximal end or the distal end of the suture that is not passed through the loop is passed through the third passageway.

86. A suture anchor assembly as recited in claim 85, further comprising a second anchor, wherein the proximal end or the distal end of the suture that is not passed through the loop is secured to the second anchor.

87. A suture anchor assembly as recited in claim 86, further comprising a channel recessed on the anchor, the channel intersecting with the first passageway and the second passageway.
