Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
106 words
Apparatus for attaching a suture to bone under soft tissue comprising in combination: a cannula having an inner bore, a drill guide telescopically received in the cannula and having at least two generally parallel bores, and a suture pusher comprising a tool having a straight section telescopically received in one of the bores of the drill guide, a laterally extending handle on one end and on the other end a suture holding section movable in response to manipulation of the handle to push a suture loop through soft bone material between two parallel holes in bone aligned with two of the bores in the drill guide.
Claim 2
Dependent Claim
106 words
Apparatus for attaching a suture to bone under soft tissue comprising in combination: a cannula having an inner bore, a drill guide telescopically received in the cannula and having at least two generally parallel bores, and a suture pusher comprising a tool having a straight section telescopically received in one of the bores of the drill guide, a laterally extending handle on one end and on the other end a suture holding section movable in response to manipulation of the handle to push a suture loop through soft bone material between two parallel holes in bone aligned with two of the bores in the drill guide.
Claim 3
Dependent Claim
92 words
A suture pusher comprising a strand of resiliently deformable wire having a straight section, a laterally extending handle on one end and on the other end an appertured and naturally curved suture pushing section which in unstressed condition extends laterally from the straight section and a sleeve telescopically surrounding the strand of wire and supporting the naturally curved suture pushing section aligned with the straight section whereby the suture pushing section deforms to said unstressed laterally extending condition responsive to manipulation of the handle to move the wire telescopically from the sleeve.
Claim 4
Dependent Claim
92 words
A suture pusher comprising a strand of resiliently deformable wire having a straight section, a laterally extending handle on one end and on the other end an appertured and naturally curved suture pushing section which in unstressed condition extends laterally from the straight section and a sleeve telescopically surrounding the strand of wire and supporting the naturally curved suture pushing section aligned with the straight section whereby the suture pushing section deforms to said unstressed laterally extending condition responsive to manipulation of the handle to move the wire telescopically from the sleeve.
Claim 5
Independent Claim
168 words
The method of attaching a suture to bone under soft tissue which comprises: inserting a cannula through soft tissue substantially to the bone, inserting into the cannula a drill guide having at least two generally parallel spaced apart bores, drilling two non-intersecting holes aligned with the bores of the drill guide into the bone through the hard surface of the bone into softer inner bone material, inserting through one of the bores and holes a suture pusher having a suture carrying end and pushing the suture carrying end, with a suture loop thereon, through the inner bone material from the one hole to the other hole, retrieving one strand of the suture loop through the other bone hole and bore, removing the pusher and the drill guide, tying a knot in the suture and passing it down the suture through the cannula, and removing the cannula leaving the suture tied to the bone with the suture encircling a bridge of hard surface bone material between the two holes.
Claim 6
Independent Claim
168 words
The method of attaching a suture to bone under soft tissue which comprises: inserting a cannula through soft tissue substantially to the bone, inserting into the cannula a drill guide having at least two generally parallel spaced apart bores, drilling two non-intersecting holes aligned with the bores of the drill guide into the bone through the hard surface of the bone into softer inner bone material, inserting through one of the bores and holes a suture pusher having a suture carrying end and pushing the suture carrying end, with a suture loop thereon, through the inner bone material from the one hole to the other hole, retrieving one strand of the suture loop through the other bone hole and bore, removing the pusher and the drill guide, tying a knot in the suture and passing it down the suture through the cannula, and removing the cannula leaving the suture tied to the bone with the suture encircling a bridge of hard surface bone material between the two holes.
Claim 7
Dependent Claim
59 words
The method of claim 3 in which the suture pusher is a strand of a resiliently flexible TiNi alloy having a straight section, a laterally extending handle on one end and on the other end a curved suture pushing section extending laterally from the straight section and resiliently deformable to pass through a bore in a generally straightened condition.
Claim 8
Dependent Claim
52 words
The method of claim 4 in which a tube is inserted through the one bore and into the one hole in the bone before inserting the suture pusher so that the tube guides the suture pusher down into the bone before pushing the suture from the one hole to the other hole.
