Abstract:
1. A wound dressing, comprising: a carrier layer, said carrier layer including a plurality of first metal particles having an electrochemical potential, a fluid soluble material, and a plurality of second metal particles having a different electrochemical potential from said plurality of first metal particles, wherein said first metal particles and said second metal particles are suspended alternatively within said fluid soluble material, wherein said fluid soluble material is comprised of a bioresorbable mixture of polylactic and polyglycolic acid and further wherein said first metal particles and said second metal particles are spaced from between 0.1 mm to 7.0 mm apart and due to their spacing generate a sustained galvanic current of between 0.1 to 1.0 millivolts when subjected to an electrolyte-containing fluid causing erosion of said carrier layer.
