PERICARDIAL ARTIFICIAL HEART VALVES CONDUIT USING DIFFERENT BIOLOGICAL TISSUE CAPABLE OF OPERATING NONINVASIVE METHOD, AND MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A pericardial artificial heart valves conduit using different biological tissue is provided no to generate denaturation and degeneration.;CONSTITUTION: A manufacturing method of pericardial artificial heart valves conduit using different biological tissue comprises: a step of forming Dacron body(20) by extracting the leaflet(11) of pericardium to rectangular shape; a step of putting valves on the Dacron body for covering a portion of the valves; a step of forming an artificial heart valves conduit, by connecting the valves and the Dacron body by using stitching fiber(30); a step of forming a space part of diamond shape by binding wire for manufacturing a stent like super elastic shape-memory alloy wire; a step of putting the space part into the inside of the stent of cylinder body; and a step of connecting the shape-memory alloy wire by wire at a plurality of places.;COPYRIGHT KIPO 2012
