         22 . A negative pressure wound therapy system, comprising:
 a non-woven material configured to be positioned on an appendage, the non-woven material configured to communicate negative pressure to a wound on the appendage;   a gas impermeable flexible housing configured to be positioned over the non-woven material, the flexible housing comprising a fold, the fold configured to be generally perpendicular to a longitudinal axis of the appendage, and wherein the flexible housing is configured such that when the flexible housing is folded back upon itself to surround the wound on the appendage, a first portion of the flexible housing is adhered to a second portion of the flexible housing.   
     
     
         23 . The negative pressure wound therapy system of  claim 22 , wherein the gasket is configured to form a seal around the circumference of the appendage, the seal configured to prevent the passage of gas. 
     
     
         24 . The negative pressure wound therapy system of  claim 22 , wherein the flexible housing further comprises a coating of adhesive on a skin-facing side of the flexible housing material. 
     
     
         25 . The negative pressure wound therapy system of  claim 22 , wherein the flexible housing comprises a liner. 
     
     
         26 . The negative pressure wound therapy system of  claim 22 , wherein the gas impermeable housing material comprises an opening, the opening configured to allow the passage of negative pressure. 
     
     
         27 . The negative pressure wound therapy system of  claim 26 , further comprising a port positioned over the opening. 
     
     
         28 . The negative pressure wound therapy system of  claim 27 , further comprising a source of negative pressure connected to the port. 
     
     
         29 . The negative pressure wound therapy system of  claim 28 , wherein the opening is located over the non-woven material. 
     
     
         30 . The negative pressure wound system of  claim 27 , wherein the port is configured to be positioned over a top of the appendage.
