Skin closure systems and devices of improved flexibility and stretchability for bendable joints
A system or device for skin closure comprises an elastic flat flexible tape elongated along a longitudinal axis and having a lower side and an opposing upper side, said tape having a pressure sensitive adhesive on at least a portion of the lower side, said tape having a plurality of openings arranged side-by-side with spaces between said openings oriented across the longitudinal axis.
1. A device for skin closure, comprising
a) an elastic flat flexible tape elongated along a longitudinal axis and having a lower side and an opposing upper side,
b) said tape comprising a mesh substrate;
said tape having a pressure sensitive adhesive on at least a portion of the lower side, further comprising:
(i) a removable mask releasably disposed on said tape and having substantially same shape as said tape;
(ii) said mask having a plurality of openings arranged side-by-side with spaces between said openings oriented across the longitudinal axis such that the mesh substrate is exposed through the plurality of openings, wherein the openings occupy between 30% and 80% of a total area of the mask, and wherein each of the plurality of openings extends from a first area proximate to a first edge of the mask, across the longitudinal axis, and to a second area proximate to a second edge of the mask; and
(iii) the mask further having one or more tabs configured for grasping for lift-off and removal of the mask.
2. The device of claim 1 , wherein the mask is made of a polymeric flexible material.
3. The device of claim 2 , wherein the polymeric flexible material is elastic.
4. The device of claim 2 , wherein the polymeric flexible material is non-elastic.
5. The device of claim 1 , wherein the mesh substrate is made of a polymeric flexible material that is elastic.
6. The device of claim 1 , wherein the mesh substrate is impregnated with an initiator configured to react with a polymerizable adhesive to accelerate polymerization.
7. The device of claim 1 , wherein the tape has a first thickness and the mesh substrate has a second thickness less than the first thickness.
8. The device of claim 1 , wherein the mesh substrate is one of a porous nonwoven, a felt, a porous woven fabric, a textile, or a foam.
9. A device for skin closure, comprising:
a) an flat flexible tape elongated along a central longitudinal axis and having a lower side and an opposing upper side,
b) said tape having a pressure sensitive adhesive on at least a portion of the lower side,
c) said tape having a plurality of openings arranged side-by-side with spaces between said openings oriented across the central longitudinal axis; and
d) said openings further arranged above and below the central longitudinal axis of said tape and separated by axial spacer areas with no openings overlapping said central longitudinal axis, wherein the openings comprise a porous mesh and said axial spacer areas are non-porous, wherein the openings occupy between 30% and 80% of a total area of the tape,
wherein a width of the openings is between 2 mm to 12 mm.
10. The device of claim 9 , wherein the tape is made of a polymeric flexible material.
11. The device of claim 10 , wherein the polymeric flexible material is elastic.
12. The device of claim 10 , wherein the polymeric flexible material is non-elastic.
13. The device of claim 9 , wherein the porous mesh is made of a polymeric flexible material that is elastic.
14. The device of claim 9 , wherein the porous mesh includes an initiator configured to react with a polymerizable adhesive to accelerate polymerization.
15. The device of claim 9 , wherein the porous mesh is one of a porous nonwoven, a felt, a porous woven fabric, a textile, or a foam.
