Abstract

Abstract A suture anchor (10) for securing a suture (20) to body tissue (38) in an arthroscopic surgical procedure. The suture anchor is an elongated tubular member (12) having first and second ends (14,16). The distal or terminal end (24) of the suture is secured to the first or leading end (14) of the suture anchor (10) with the suture (20) extending through the suture anchor (10). A slot (18) is formed on the suture anchor (10) which extends from the second or trailing end (16) of the suture anchor (10) toward the leading end (14) of the suture anchor (10). The suture anchor (10) is inserted in a first position with the suture (20) extending through the suture anchor (10) from the leading end (14) of the suture anchor (10) to the trailing end (16). The suture (20) shifts from the first position approximately 90 degrees to a second position wherein the suture (20) extends from the leading end (14) of the anchor to the base (26) of the slot (18) with the length of the suture anchor (10) extending transverse to the free end (25) of the suture (20) located outside of the suture anchor (10). The method disclosed includes the steps of inserting the suture anchor (10) with the suture (20) extending longitudinally through the anchor (10) and shifting the orientation of the anchor (10) until the suture (20) extends through a slot (18) in the anchor (10) with the anchor (10) disposed in the body tissue (38) generally transverse to the free end (25) of the suture. A series of stop members, such as spheres, ribs or ridges (50, 72, 92), can be molded or placed on the suture (20) for mating with a locking member (52, 74, 90) in order to hold torn or fractured pieces of body tissue together until they are reattached or healed. <IMAGE>

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 66 words
An anchor for securing a strand of suture material in the body comprising a tube (12) having a leading end (14) and a trailing end (16), a slot (18) extending from said trailing end (16) to a point intermediate said leading and trailing ends, wherein said trailing end (16) defines a trailing face disposed at an oblique angle to the central axis of the tube (12).
Claim 2
Dependent Claim 27 words
The anchor of Claim 1 wherein said leading end (14) defines a leading face disposed at an oblique angle to the central axis of the tube (12).
Claim 3
Dependent Claim 30 words
The anchor of Claim 1 wherein the slot (18) extends from the axially inboard region of the trailing face (16) to an intermediate point between said leading and trailing ends.
Claim 4
Dependent Claim 52 words
An anchor as defined in Claim 1 and a strand of suture material in combination, said anchor (10) comprising means for attaching said strand of suture material (20) to the leading end (14) of the tube (12) with the strand extending from the leading end at least partially through the tube (12).
Claim 5
Dependent Claim 19 words
The combination of Claim 4 wherein said means for attaching is carried by said strand of suture material (20).
Claim 6
Dependent Claim 46 words
The combination of Claim 5 wherein said means for attaching is a knot tied in the strand at the terminal end of the strand (20) which engages the leading end (14) of the tube (12) when tension is applied to the other end of the strand.
Claim 7
Dependent Claim 33 words
The combination of Claim 5 further including a locking member (52; 74) for cooperating with said means for attaching to hold said combination together to secure at least two pieces of tissue together.
Claim 8
Dependent Claim 25 words
The combination of Claim 7 wherein said means for attaching includes a series of enlargements (50; 72) for mating with said locking member (52; 74).
Claim 9
Dependent Claim 24 words
The combination of Claim 7 wherein said anchor, said strand, said means for attaching and said locking member are made from a bioabsorbable material.
Claim 10
Dependent Claim 43 words
The combination of Claim 4 wherein said strand (20) is shiftable between an insertion position in which said strand exits said tube (12) at the trailing end (16) and a toggle position in which said strand exits the tube through said slot (18).
