Abstract

Disclosed is a carrier-delivered dressing comprising a conformable film having first and second surfaces and a continuous outer perimeter. The conformable film includes a continuous strip of pressure-sensitive adhesive disposed on the first surface along a generally C-shaped first portion of the outer perimeter, and a second portion of the outer perimeter which is substantially adhesive-free. One or more release liners are provided which cover and protect the pressure-sensitive strip of adhesive prior to application. Alternative embodiments including a substantially continuous strip of pressure-sensitive adhesive around the continuous outer perimeter with one or more optionally removable release liners are also disclosed. Methods of use in which the dressings are applied in a shingled manner enable the convenient protection of long incisions or lacerations.

19. ) The carrier-delivered dressing of claim 15 wherein the carrier is clear.

20. ) The carrier-delivered dressing of claim 15 wherein the carrier includes a cut defining a window, enabling visualization through the window of an application surface during the application process.

21. ) The carrier-delivered dressing of claim 15 further comprising a low-adhesion coating on at least a portion of the second surface of the conformable film.

22. ) The carrier-delivered dressing of claim 15 wherein the device is packaged in roll form with the central axis of the roll corresponding approximately to the fourth edge of the conformable film.

23. ) A carrier-delivered dressing comprising:

a) a conformable film having first and second surfaces and first, second, third and fourth edges;

b) a strip of pressure-sensitive adhesive disposed on said first surface along each one of said first, second, third and fourth edges;

c) one or more release liners covering said pressure-sensitive adhesive along said first, second and third edges;

d) an optionally removable release liner covering the pressure-sensitive adhesive disposed along at least a portion of the fourth edge, the optionally removable release liner being removable independently of other release liners associated with the carrier-delivered dressing; and

e) a carrier releasably attached to at least a portion of the second surface of the conformable film.

24. ) The carrier-delivered dressing of claim 23 wherein the conformable film has a major and a minor axis and the fourth edge is oriented in a direction generally parallel with the minor axis.
