Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
146 words
A surgical needle for fascial suturing comprising: a) a solid arcuate body segment curving in a concave manner, said body segment having an internal radius of curvature around a center point, and said body segment terminating at a sharp point; b) a straight shank segment having a suture attached at a terminal end thereof, said shank segment having a length not substantially greater than said internal radius of curvature of said body segment; and c) a solid neck segment positioned intermediate and connecting together said body segment and said shank segment, said neck segment curving in a convex manner relative to said body segment whereby said shank segment is attached to said body segment at an angle such that an extension of an axial centerline of said shank segment intersects said arcuate body segment of the needle in a central third portion of said body segment.
Claim 2
Dependent Claim
146 words
A surgical needle for fascial suturing comprising: a) a solid arcuate body segment curving in a concave manner, said body segment having an internal radius of curvature around a center point, and said body segment terminating at a sharp point; b) a straight shank segment having a suture attached at a terminal end thereof, said shank segment having a length not substantially greater than said internal radius of curvature of said body segment; and c) a solid neck segment positioned intermediate and connecting together said body segment and said shank segment, said neck segment curving in a convex manner relative to said body segment whereby said shank segment is attached to said body segment at an angle such that an extension of an axial centerline of said shank segment intersects said arcuate body segment of the needle in a central third portion of said body segment.
