Topical devices and methods for assisting performance of surgical incision
A flexible topical device for assisting performance of surgical incision comprises a tear-resistant support layer and an adhesive layer disposed thereon. The device can further comprises a tear-resistant reinforcement layer disposed adjacent to the support layer. The device is adhesively attached to a surface of the tissue in which an incision is to be made, adjacent to the incision. The device prevents or limits an initiation or propagation of a tear in the tissue resulting from the stresses or strains imposed on the incision.
1 . A flexible topical device comprising a support layer and an adhesive layer disposed on a surface of the support layer, wherein the support layer comprises a tear-resistant material, the topical device is deformable to follow a contour of a surface of a tissue on which the device is to be attached, and the adhesive layer comprises a biocompatible adhesive.
2 . The topical device of claim 1 , wherein the support layer comprises a plurality of reinforcement members embedded in a matrix.
3 . The topical device of claim 1 , further comprising a tear-resistant reinforcement layer that is disposed adjacent to, and overlaps at least a portion of, the support layer.
4 . The topical device of claim 1 , wherein the support layer is capable of preventing or limiting an initiation or propagation of a stress- or strain-induced tear in a tissue resulting from an incision made therein when the topical device is disposed on the tissue adjacent to the incision.
5 . The topical device of claim 4 , wherein the support layer or the adhesive layer further comprises a medicament selected from the group consisting of analgesic drugs, anesthetic drugs, anti-infective drugs, anti-inflammatory drugs, anti-allergic drugs, antibiotic drugs, and combinations thereof.
6 . The topical device of claim 4 , wherein the topical device comprises an opening.
7 . The topical device of claim 2 , wherein the support layer is capable of preventing or limiting a propagation of a tear in a tissue resulting from an incision made therein when the topical device is disposed on the tissue adjacent the incision.
8 . The topical device of claim 7 , wherein the support layer or the adhesive layer further comprises a medicament selected from the group consisting of analgesic drugs, anesthetic drugs, anti-infective drugs, anti-inflammatory drugs, anti-allergic drugs, antibiotic drugs, and combinations thereof.
9 . The topical device of claim 3 , wherein the device is configured to cover an area between the vagina and the anus and areas on both sides of the anus, but does not cover a posterior area opposite to the vagina.
10 . The topical device of claim 3 , wherein a first portion of the adhesive layer opposite to, and less than an area of, the reinforcement layer, and a second portion of the adhesive layer, which is contiguous with the first portion and extends away from the reinforcement layer, are free of adhesive.
11 . The topical device of claim 3 , wherein the device is configured to cover an area between the vagina and the anus and an area surrounding the anus, and has an opening over the anus.
12 . The topical device of claim 3 , wherein the support layer and the reinforcement layer are substantially non-stretchable.
13 . The topical device of claim 1 , wherein the support layer is substantially non-stretchable.
14 . A method for preventing or limiting an initiation or propagation of a tear in a tissue that results from an incision made in the tissue, the method comprising:
attaching a flexible topical device on a surface of the tissue adjacent to, and in a direction of, the incision,
wherein the topical device comprises a tear-resistant support layer and an adhesive layer disposed on a surface of the support layer, wherein the support layer comprises a tear-resistant material, the topical device is deformable to follow a contour of a surface of the tissue on which the device is attached, and the adhesive layer comprises a biocompatible adhesive, and wherein the adhesive layer comes into contact with the surface of the tissue.
15 . The method of claim 14 , further comprising preparing the surface of the tissue before attaching the topical device.
16 . The method of claim 14 , wherein the incision is made in an episiotomy procedure and the topical device is attached to an area between the vagina and the anus.
17 . The method of claim 14 , wherein the topical device further comprises a tear-resistant reinforcement layer disposed adjacent to the support layer.
18 . The method of claim 17 , wherein the topical device has an opening over the anus.
19 . The method of claim 17 , wherein the topical device covers an area between the vagina and the anus and areas on both sides of the anus, but does not cover a posterior area opposite to the vagina.
20 . The method of claim 17 , wherein an area of the adhesive layer over the anus is free of adhesive.
