Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
A surgical wound closure tape, said tape having a longitudinal direction and a transverse direction, said tape comprising a substrate of a nonwoven fabric, one surface of said substrate being smooth and having a pressure-sensitive adhesive uniformly disposed over said smooth surface, the opposite surface of said substrate having a plurality of indentations disposed over said surface, each indentation being rectangular in shape, each said rectangle having a length of at least 5 times the width of said rectangle, said rectangles being disposed in parallel rows with the length of each rectangle extending in the transverse direction of the tape, the rectangles in adjacent rows being in overlapping relationship with each rectangle spaced from all adjacent rectangles by a distance equal to or greater than the width of the rectangle whereby said tape has good elasticity, drape, abrasion resistance, tensile strength, and a reduced propensity to curl at the edges of the tape.
Claim 2
Dependent Claim
153 words
A surgical wound closure tape, said tape having a longitudinal direction and a transverse direction, said tape comprising a substrate of a nonwoven fabric, one surface of said substrate being smooth and having a pressure-sensitive adhesive uniformly disposed over said smooth surface, the opposite surface of said substrate having a plurality of indentations disposed over said surface, each indentation being rectangular in shape, each said rectangle having a length of at least 5 times the width of said rectangle, said rectangles being disposed in parallel rows with the length of each rectangle extending in the transverse direction of the tape, the rectangles in adjacent rows being in overlapping relationship with each rectangle spaced from all adjacent rectangles by a distance equal to or greater than the width of the rectangle whereby said tape has good elasticity, drape, abrasion resistance, tensile strength, and a reduced propensity to curl at the edges of the tape.
Claim 3
Dependent Claim
18 words
A surgical wound closure tape in accordance with claim 1 wherein the substrate is a spunbonded nonwoven fabric.
Claim 4
Dependent Claim
17 words
A surgical tape in accordance with claim 2 wherein the spunbonded fabric comprises randomly disposed nylon filaments.
Claim 5
Dependent Claim
23 words
A surgical wound closure tape according to claim 1 wherein the length of each rectangle is 6 times the width of the rectangle.
