Abstract
Abstract A method of treating heart valve dysfunction in a human patient in which the dysfunctioning valve is replaced with a novel bioprosthesis. The novel bioprosthesis comprises a porcine pulmonary valve, which has preferably been treated to fix and also sterilize the valve tissue. The porcine pulmonary valve may either be stent mounted to facilitate its surgical implantation into the patient, or it may be unstented to reduce the possibility of embolism and thrombosis.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
21 words
A method of treating valve dysfunction in a human patient, comprising replacing the existing dysfunctioning valve with a porcine pulmonary valve.
Claim 2
Independent Claim
21 words
A method of treating valve dysfunction in a human patient, comprising replacing the existing dysfunctioning valve with a porcine pulmonary valve.
Claim 3
Dependent Claim
21 words
A method as defined in claim 1 wherein the existing valve is replaced with a fixed and sterilized porcine pulmonary valve.
Claim 4
Dependent Claim
30 words
A method as defined in claim 1 or 2 wherein the dysfunctioning valve is the aortic or pulmonary valve, which dysfunctioning valve is replaced with an unstented porcine pulmonary valve.
Claim 5
Dependent Claim
54 words
The method as defined in claim 1 or 2 wherein the dysfunctioning valve is the aortic valve, which dysfunctioning valve is replaced with an unstented porcine pulmonary valve having a flexible sewing skirt extending from the inlet side of the valve to facilitate suturing of the valve into communication with the patient's left ventricle.
Claim 6
Dependent Claim

A method as defined in claim 1 or 2 wherein the dysfunctioning valve is the aortic, mitral or tricuspid valve, which dysfunctioning valve is replaced with a stent-mounted porcine pulmonary valve.
Claim 7
Dependent Claim
17 words
A bioprosthesis suitable for replacing a human patient's valves comprising a fixed and sterilized porcine pulmonary valve.
Claim 8
Dependent Claim
17 words
A bioprosthesis suitable for replacing a human patient's valves comprising a fixed and sterilized porcine pulmonary valve.
Claim 9
Dependent Claim
41 words
A bioprosthesis as defined in claim 6 wherein said porcine pulmonary valve is unstented and has a flexible sewing skirt extending from the inlet side of the valve to facilitate suturing of the valve into communication with the patient's valve annulus.
Claim 10
Dependent Claim
15 words
A bioprosthesis as defined in claim 6 wherein said porcine pulmonary valve is stent mounted.
Claim 11
Dependent Claim
15 words
A bioprosthesis suitable for replacing a human patient's valve, comprising an excised porcine pulmonary valve.
Claim 12
Dependent Claim
15 words
