Abstract:
1. A prosthetic heart valve replacement system for valve replacement in a patient's valve annulus during surgery, enabling a reduction of time duration that the patient is subjected to a heart-lung machine during prosthetic heart valve replacement, comprising: a first outer anchoring ring which is flanged and fastened to the patient's heart valve annulus during surgery, and a second inner valve ring which is flanged and to which a prosthetic heart valve is attached outside of the patient, such as by suturing; the second inner valve ring being configured to be assembled to be captively and snugly held concentrically inside of said first outer anchoring ring, wherein said first outer anchoring ring and said second inner valve ring are made of material which remains noncorrosive even when subjected to prolonged use inside of the patient's heart, and wherein the first outer anchoring ring and the second inner valve ring each have a generally tubular configuration with a horizontal inwardly projecting flange at one end, the second inner valve ring being configured to be circumferentially resilient when compressed radially inwards, so as to be captively held within the first outer anchoring ring upon assembly.
