Stentless bioprosthetic cardiac valve
First Claim
1. A self-supporting stentless cardiac valve bioprosthesis of the type fixable to a patient'"'"'s aortic ring for replacing an explanted valve comprising:
- a tubular body of animal origin defining a flow passageway therethrough having a proximal and a distal end;
a multi-valve obturator adjacent the proximal end of the tubular body for closing the flow passageway, each valve of the multi-valve obturator capable of rotating about a fulcrum adjacent an outer circumference of the flow passageway;
a suture ring having a continuous annular cord disposed adjacent the fulcrum of each valve of the multi-valve obturator and being directly fixable to the patient'"'"'s aortic ring; and
a textile coating compatible with the human body coating an outer surface of the tubular body and said continuous annular cord.

Abstract
A self-supporting cardiac valve bioprosthesis of the type fixable to the patient'"'"'s aortic ring for replacing an explanted valve. The bioprosthesis consists of a tubular body having a flow passageway therethrough and having a proximal and a distal end. A multi-valve obturator is located adjacent the proximal end of the tubular body for closing the flow passageway. Each valve of the multi-valve obturator is capable of rotating about a fulcrum adjacent an outer circumference of the flow passageway. A suture ring is provided having a continuous annular cord forming the fulcrum of each valve of the multi-valve obturator which cord is directly fixable to a patient'"'"'s aortic ring. A textile coating compatible with the human body coats the outer surface of the tubular body and the continuous annular cord.
