Patent ID: 8497408

Claim:
A method for treating a high pressure bleeding wound, comprising the steps of: inserting one or more medical devices which generate a back-pressure directly in said high pressure bleeding wound, each of said one or more medical devices comprising (i) a swellable material; and (ii) a membrane having a first side and a second side, said membrane retaining said swellable material on said first side and permitting blood to pass through from said second side to said first side of said membrane, said swellable material being swellable upon contact with blood which passes through said membrane from said second side to said first side, said membrane being expandable upon swelling of said swellable material, and said swellable material and said membrane having attributes whereby swelling of said swellable material and expansion of said membrane within said bleeding wound fills said bleeding wound and generates a back pressure in said bleeding wound of at least 60 mm Hg pressure within three minutes of being placed in said bleeding wound; and permitting said one or more medical devices to swell within said bleeding wound and to develop a back pressure within said bleeding wound.
