A method for treating a wound, comprising: i. locating a flexible adhesive cover over the wound to provide a chamber between the cover and the wound, said cover adapted for maintaining reduced pressure at the wound; ii. adhesively sealing and adhering the periphery of said cover to tissue surrounding the wound; iii. operably connecting a vacuum system with said chamber at said seal for producing said reduced pressure; iv. interposing a fluid trap between said cover and said vacuum system; and v. maintaining reduced pressure to promote the formation of granulation tissue at the wound until the wound has progressed toward a selected stage of healing. view more

A method of treating a wound comprising the steps of: i. providing a vacuum source capable of providing at least 0.11 atm of reduced pressure; ii. locating a flexible adhesive cover over the wound, said cover having a suction port; iii. Locating a porous material comprising a synthetic polymer under said cover at the wound; iv. adhesively sealing and adhering the periphery of said cover to tissue surrounding the wound to form a continuous seal; v. operably connecting said suction port with said vacuum system for producing said reduced pressure; v. interposing a fluid trap between said suction port and said vacuum source; and vi. maintaining reduced pressure of at least 0.11 atm at the wound until the wound had progressed toward a selected stage of healing. view more

The method according to claim 20, comprising locating a porous material comprising a synthetic polymer under the cover at the wound.

The method according to claim 42 or 108, wherein the porous material comprises foam.

The method according claim 20, 42, or 108, wherein the wound comprises a pressure sore.

The method according claim 20, 42, or 108, wherein the selected stage of healing comprises re-epithelialization of at least a portion of the wound.
