Abstract
Abstract The present invention relates to the implantation of one or more prosthetic valve(s) in the pulmonary vein(s) of a subject for decreasing or preventing an increase in pulmonary venous pressure. The present invention accordingly provides for novel treatment strategies for the treatment of medical disorders associated with elevated pulmonary venous pressure, including congestive heart failure, as well as for prosthetic pulmonary vein valves and their delivery systems. Expandable as well as fixed-dimension non-expandable pulmonary vein prosthetic valves for implantation by a variety of surgical and percutaneous procedures are also described.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
28 words
A method of lowering mean pulmonary venous pressure in a subject, comprising creating an effective unidirectional partitioning between the left atrium and a pulmonary vein of the subject.
Claim 2
Independent Claim
28 words
A method of lowering mean pulmonary venous pressure in a subject, comprising creating an effective unidirectional partitioning between the left atrium and a pulmonary vein of the subject.
Claim 3
Dependent Claim
38 words
The method of claim 1 , where unidirectional partitioning is achieved by implanting a prosthetic valve in a location selected from the group consisting of a pulmonary vein, an ostium of a pulmonary vein, and a left atrium.
Claim 4
Dependent Claim
20 words
The method of claim 1 , where partitioning is achieved between the left atrium and more than one pulmonary vein.
Claim 5
Dependent Claim
56 words
The method of claim 3 , where partitioning is achieved between the more than one pulmonary vein and the left atrium by implanting, as to each pulmonary vein subject to partitioning, a prosthetic valve in a location selected from the group consisting of the pulmonary vein, the ostium of the pulmonary vein, and the left atrium.
Claim 6
Dependent Claim
18 words
The method of claim 1 which is used for the treatment of congestive heart failure in the subject.
Claim 7
Dependent Claim
18 words
The method of claim 2 which is used for the treatment of congestive heart failure in the subject.
Claim 8
Dependent Claim
18 words
The method of claim 2 , where the prosthetic valve is a diaphragm-type pulmonary vein prosthetic valve device.
Claim 9
Dependent Claim
18 words
The method of claim 2 , where the prosthetic valve is a trapdoor-type pulmonary vein prosthetic valve device.
Claim 10
Dependent Claim
18 words
The method of claim 2 , where the prosthetic valve is a stocking-type pulmonary vein prosthetic valve device.
Claim 11
Dependent Claim
18 words
The method of claim 2 , where the prosthetic valve is a windsock-type pulmonary vein prosthetic valve device.
Claim 12
Dependent Claim
19 words
The method of claim 2 , where the prosthetic valve is implanted by percutaneously accessing the pulmonary vein ostium.
Claim 13
Dependent Claim
17 words
The method of claim 2 , where the prosthetic valve is implanted by an open-heart surgical procedure.
Claim 14
Dependent Claim
51 words
The method of claim 2 , where the prosthetic valve is implanted by a method comprising: (i) surgically accessing the pulmonary vein; (ii) introducing the prosthetic valve first into the pulmonary vein and then advancing the prosthetic valve to the ostium; and (iii) deploying the prosthetic valve in the desired location.
