1. A suture buttress system, comprising:
- a suture retriever including a handle portion with an elongate member extending therefrom, the elongate member having an outer surface and a distal end that includes a suture retaining element; and
a suture buttress comprising a resilient hollow tube having an outer surface and opposed proximal and distal ends, the suture buttress being removably and replaceably disposed on the elongate member such that when the suture retaining element extends beyond the distal end of the suture buttress, the sutress buttress retaining element is operable through the distal end of the hollow tube.

Abstract
A suture buttress system has a suture retriever and a suture buttress. The suture retriever includes a handle portion with an elongate member extending therefrom and having an outer surface and a distal end that includes a suture retaining element. The suture buttress comprises a resilient hollow tube having an outer surface and opposed ends. The suture buttress is removably and replaceably disposed on the elongate member. The suture buttress may further include an external fastening element suitable to retain the suture buttress within a bone tunnel. A suture buttress deployment tool may also be provided.

18. A bone tunnel buttress system, comprising:
-
a suture retriever including a handle portion with an elongate member extending therefrom, the elongate member having an outer surface and a distal end that includes a suture retaining element; and
a bone tunnel buttress comprising a resilient hollow tube with an outer surface and opposed proximal and distal ends, the bone tunnel buttress being removably and replaceably disposed on the elongate member such that the suture retaining element is operable through the distal end of the hollow tube, the bone tunnel buttress further including at least one external fastening element on the outer surface, the external fastening element being effective to allow the bone tunnel buttress to slide into a bone tunnel in a first direction when urged into the bone tunnel by the suture retriever while preventing the bone tunnel buttress from sliding out of the bone tunnel in a second direction that is substantially opposed to the first direction upon removal of the suture retriever from the bone tunnel. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)

26. A bone tunnel buttress, comprising:
-
a bioimplantable elongate hollow tube having an outer surface and opposed proximal and distal ends;
at least one external fastening member formed on the outer surface of the tube, the bone tunnel buttress being effective for deployment within a bone tunnel such that the external fastening member prevents removal of the bone tunnel buttress from the bone tunnel in a direction opposite to a direction of insertion of the bone tunnel buttress within the bone tunnel; and
wherein the external fastening element comprises at least one slit formed in at least a portion of the outer surface of the tube, the at least one slit being formed at an angle other than 90 degrees to a plane transverse to a longitudinal axis of the tube such that when the tube is flexed, a raised edge extends outward from the outer surface of the bone tunnel buttress. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A method for attaching soft tissue to a bone comprising the steps of:
-
forming a first hole at least through cortical bone tissue of the bone proximate to the soft tissue attachment site;
forming a second hole at least through cortical bone tissue of the bone spaced a predetermined distance apart from the first hole;
connecting the first hole and the second hole though subcortical bone tissue to form a tunnel in the bone;
attaching a suture thread to the soft tissue to be attached;
providing a suture buttress system comprising;
a suture retriever including a handle portion with an elongate member extending therefrom, the elongate member having an outer surface and a distal end that includes a suture retaining element; and
a suture buttress comprising a resilient hollow tube having an outer surface and opposed ends, the suture buttress being removably and replaceably disposed on the elongate member;
inserting the distal end of the elongate member of the suture buttress system into the second hole at least until the distal end of the elongate member reaches the first hole;
engaging a suture attached to the soft tissue with the suture retaining element; and
removing the suture retriever from the bone tunnel so as to draw the suture through the bone tunnel and the suture buttress while leaving the suture buttress within the tunnel. - View Dependent Claims (37, 38, 39, 40)
