IMPLANTABLE PROSTHESIS OF PTFE HAVING IMPROVED ADAPTABILITY TO BLOOD AND TISSUE AND SUPERIOR PATENCY

摘要

PURPOSE: To provide improved biologically compatible fluoropolymer material which can be implanted. CONSTITUTION: Biologically compatible fluoropolymer material forms an extrusion feeding flow of the first fluoropolymer component containing perfluorosulfonate copolymer and the second fluoropolymer component containing a fluoropolymer and is prepared by extruding the feeding flow and forming an extrusion. The resultant biologically compatible fluoropolymer material is useful, for example, for an artificial blood vessel.
