| description | The techniques of this disclosure generally relate to a valve prosthesis including a one piece molded prosthetic valve and a stent structure having an outflow crown ring. The outflow crown ring includes inferior crowns, superior crowns, and outflow crown struts connected to the superior crowns and the inferior crowns. An internal radius of the superior crowns is within the range of 0.3 to 0.5 millimeters (mm). The internal radius of the superior crowns is made sufficiently large to prevent flaring outward of the superior crowns on deployment and to make the superior crowns atraumatic. This reduces and essentially eliminates the chance of contact with the aortic sinus or the ascending aorta. Further, in the event there is contact, the atraumatic shape of the superior crowns minimizes the abrasion of the vessel. |
