Patent 8445554 was granted and assigned to Kensey Nash Corporation on May, 2013 by the United States Patent and Trademark Office.
A high strength porous polymeric material manufactured by a compression process is disclosed. The material results in a network of interconnected collapsed pores, which forces thin overlapping walls and passages to be created. The network provides permeable access for fluid migration throughout the material. The strength and/or permeability are advantageous for medical devices and implants.
