Prosthetic cardiac valve

摘要: A prosthetic aortic or pulmonary valve for permanent cardiac implantation into the natural root having a framework which is made from sheet woven of knitted textile fabric material and consists an annular ring with three equiangularly spaced projecting legs extend substantially parallel to one another in axial direction ring. Each leg folded about its longitudinal center line so that side edges form radially outwardly flanges, adjacent flanges merging through curves portion lying between those two whereby U-shaped continuous flange formed each pair pairs legs. The supports separate cusps thin flexible impermeable material, cusp edge overlies bonded it, free extends ends corresponding has length equivalent third internal diameter
