(57) [Abstract] [Purpose] A heart valve molding disk that has a high degree of surface finish and combines all the advantageous characteristics such as durability, long life, stress resistance, wear resistance, and blood compatibility. Modified ultra-high molecular weight polyethylene (UHMW-P To provide an improved valvular disc using E) and a method for manufacturing the same. [Structure] A suture ring is attached to the outer periphery of the leaflet housing, and a disc blocker is attached to the inner periphery of the leaflet housing A disc closure is tiltably held to a support in the leaflet housing closed space, a suture ring is attached to a grooved ring outside the leaflet housing, and the leaflet housing is It is made of cobalt / nickel based or cobalt / chromium / tungsten based alloy or titanium or its alloys. |
