Abstract
A wound closure system and method having a porous pad for providing a reduced pressure to a tissue site is disclosed. The porous pad comprises a porous material formed by spraying a chemical substance that cures to form the porous material which has a body and an outer surface. Both the body and the outer surface have pores wherein the average size of the pores in the outer surface is smaller than the average size of the pores in the body. The porous pad further comprises a pathway formed within the porous material that is adapted to fluidly communicate with a source of reduced pressure.
