Catheter Delivered Valve Having a Barrier to Provide an Enhanced Seal
First Claim
1. A vascular valve replacement system, the system comprising:
- a conduit;
a catheter;
a prosthetic valve device including a valve connected to a support structure, the valve device disposed on the catheter; and
a barrier member disposed about an outer surface of the support structure of the valve device, the barrier member comprising a layer of material that will fill space between the valve support structure and the conduit wall when the support structure is deployed in the conduit;
wherein when the prosthetic valve device is deployed from the catheter in the conduit, the barrier member prevents blood flow between the conduit and the outer surface of the support structure of the valve device.

Abstract
A system for treating abnormalities of the right ventricular outflow tract includes a prosthetic valve device having a barrier material contacting at least a portion of the outer surface of the valve device. One embodiment of the invention includes a barrier member attached to the exterior surface of the valve device. Another embodiment includes a barrier material that is injected within the vascular system. Yet another embodiment of the invention includes a method for replacing a pulmonary valve that includes forming a barrier around the outer surface of a replacement valve and preventing blood flow around the replacement valve.

9. A pulmonary valve replacement system, the system comprising:
-
a conduit having a lumen defined by an inner wall;
a catheter;
a prosthetic valve device including a valve connected to a support structure, the valve device positioned in the conduit, and a barrier disposed about at least a portion of the outer surface of the support structure, wherein the barrier is deployed via the catheter between the conduit and the outer surface of the support structure of the valve device to prevent blood flow there between. - View Dependent Claims (10, 11, 12)

13. A pulmonary valve replacement system, the system comprising:
-
a conduit;
a prosthetic valve device including a valve connected to a support structure, the valve device positioned in the conduit, and a barrier member disposed about at least a portion of the outer surface of the support structure, the barrier member comprising a layer of material that will fill space between the valve support structure and the conduit wall when the support structure is deployed in the conduit;
wherein the barrier member contacts an inner surface of the conduit, and thereby prevents blood flow between the conduit and the outer surface of the support structure of the valve device. - View Dependent Claims (14)

-
delivering a prosthetic valve device including a valve connected to a support structure having a barrier disposed about at least a portion of an outer surface of the support structure to a treatment site within a conduit via catheter;
deploying the prosthetic valve device from the catheter;
positioning the prosthetic valve device within a conduit;
forming a barrier around the outer surface of the support structure; and
preventing blood flow around the support structure via the barrier. - View Dependent Claims (16, 17, 18, 19, 20)
