INDICIA FOR PROSTHETIC DEVICE

摘要

A prosthetic stentless aortic tissue valve (10A) includes a substantially annular valve body (12) having a leaflet (34) carried therein for occluding blood flow therethrough. A root (14) extends generally coaxially from the valve body (12). Visual markings (28) are provided on the root and act as a sculpting guide for a surgeon during implantation of the prosthetic heart valve (10A) to sculpt portions of sinus areas of the root.
