Abstract
Abstract Suture devices, particularly useful in endoscopic surgery, include a suture device made of bioabsorbable material having an elongate body member with a sharp distal end for penetrating tissue and means for locking the suture device in tissue to prevent forward and rearward movement and a suture device made of bioabsorbable material having a hinge-like joint for folding a distal portion at a precise location to be juxtaposed with a proximal portion for adjustable locking. Methods of using the suture devices for joining tissue sections, such as in tuboplasty, for closing anatomical lumens and for subcuticular suturing.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
113 words
A needle-like suture device for joining bodily tissue comprising an elongate body member integrally, unitarily made of bioabsorbable material having a sharp distal end for penetrating tissue and a proximal end; means carried on said proximal end for abutting the tissue and preventing movement of said proximal end forwardly through the tissue; and means carried on said body member at least at a position adjacent said means carried on said proximal end for moving forwardly through the tissue with said body member and for engaging the tissue to prevent movement of said body member rearwardly through the tissue when said means carried on said proximal end is in abutting relation with the tissue.
Claim 2
Dependent Claim
113 words
A needle-like suture device for joining bodily tissue comprising an elongate body member integrally, unitarily made of bioabsorbable material having a sharp distal end for penetrating tissue and a proximal end; means carried on said proximal end for abutting the tissue and preventing movement of said proximal end forwardly through the tissue; and means carried on said body member at least at a position adjacent said means carried on said proximal end for moving forwardly through the tissue with said body member and for engaging the tissue to prevent movement of said body member rearwardly through the tissue when said means carried on said proximal end is in abutting relation with the tissue.
Claim 3
Dependent Claim
42 words
A suture device as recited in claim 1 wherein said means carried on said proximal end includes an enlarged end having a dimension in at least one direction transverse to said body member greater than the transverse dimension of said body member.
Claim 4
Dependent Claim
16 words
A suture device as recited in claim 2 wherein said enlarged end has a bulbous configuration.
Claim 5
Dependent Claim
36 words
A suture device as recited in claim 3 wherein said means carried on said body member includes protrusion means extending rearwardly from said body member permitting only forward movement of said body member through the tissue.
Claim 6
Dependent Claim
36 words
A suture device as recited in claim 1 wherein said means carried on said body member includes protrusion means extending rearwardly from said body member permitting only forward movement of said body member through the tissue.
Claim 7
Dependent Claim
15 words
A suture device as recited in claim 5 wherein said protrusion means are whisker-like filaments.
Claim 8
Dependent Claim
91 words
A needle-like suture device for joining bodily tissue comprising an elongate body member made of bioabsorbable material having a sharp distal end for penetrating tissue and a proximal end; means carried on said proximal end for preventing movement of said proximal end forwardly through the tissue; and a plurality of whisker-like filament means carried on said body member and extending rearwardly from said body member for moving forwardly through the tissue with said body member and for engaging the tissue to prevent movement of said body member rearwardly through the tissue.
Claim 9
Dependent Claim
91 words
A needle-like suture device for joining bodily tissue comprising an elongate body member made of bioabsorbable material having a sharp distal end for penetrating tissue and a proximal end; means carried on said proximal end for preventing movement of said proximal end forwardly through the tissue; and a plurality of whisker-like filament means carried on said body member and extending rearwardly from said body member for moving forwardly through the tissue with said body member and for engaging the tissue to prevent movement of said body member rearwardly through the tissue.
Claim 10
Dependent Claim
24 words
A suture device as recited in claim 7 wherein said whisker-like filament means are disposed along substantially the entire length of said body member.
Claim 11
Dependent Claim
32 words
A suture device as recited in claim 8 wherein said body member has a curved configuration such that continuous forward movement of said body member causes bodily tissue sections to be approximated.
Claim 12
Dependent Claim
16 words
A suture device as recited in claim 8 wherein said body member has a coiled configuration.
Claim 13
Dependent Claim
22 words
A suture device as recited in claim 10 wherein said coiled configuration is a spiral formed of coils having the same diameter.
Claim 14
Dependent Claim
29 words
