1. An absorbent substrate for transplanting a skin graft, comprising:
- a base layer having a plurality of pores and having at least one adhesive site adapted to contact at least one excised skin graft and capture said graft for removal from a donor site;
a sealing member peripherally joined to the base layer and defining an enclosure therebetween;
an absorbent material disposed within the enclosure; and
at least a first wicking layer and a second wicking layer disposed in the enclosure between the base layer and the absorbent material, said first wicking layer having a grain structure adapted to transport fluid in a lateral direction along a surface thereof, the second wicking layer being disposed adjacent to the sealing member and the first and second wicking layers being joined together to form a seal that encloses the absorbent material;
wherein at least a portion of the base layer is in fluid communication with the absorbent material to capture fluids.

Abstract
Methods and devices for management of fluids during skin graft transplantation are disclosed. In one aspect of the invention, absorbent substrates for transplanting skin grafts are disclosed having a surface adapted to contact at least one excised skin graft and engage said graft for removal from a donor site; a sealing member at least partially surrounding an absorbent material disposed within the enclosure; wherein at least a portion of the skin-contacting surface is porous and in fluid communication with the absorbent layer to capture fluids.

40. An absorbent substrate for transplanting a skin graft, comprising:
-
a base layer having a plurality of pores and having at least one adhesive site adapted to contact at least one excised skin graft and capture said graft for removal from a donor site, said pores having an average width in a range of about 1 nanometer to about 10 micrometers; a sealing member peripherally joined to the base layer and defining an enclosure therebetween; an absorbent material disposed within the enclosure; and at least a first wicking layer and a second wicking layer disposed in the enclosure between the base layer and the absorbent material, the second wicking layer being disposed adjacent to the sealing member and the first and second wicking layers being joined together to form a seal that encloses the absorbent material; wherein at least a portion of the base layer is in fluid communication with the absorbent material to capture fluids. - View Dependent Claims (41, 42, 43, 44)
