Abstract

A pulmonary valve replacement system having a vascular conduit and a prosthetic valve device including a valve operably connected to a support structure. The prosthetic valve device is positioned within the vascular conduit. A conduit support includes a substantially circular cross-section. The conduit support is positioned adjacent to and reinforces the vascular conduit. In one embodiment, the pulmonary valve replacement system includes a catheter and an inflatable member operably attached to the catheter. The prosthetic valve device is disposed on the inflatable member. The invention provides a method for replacing a pulmonary valve including providing a vascular conduit positioned at a treatment site. The vascular conduit includes a conduit support positioned adjacent the vascular conduit. A prosthetic valve device is deployed within the vascular conduit via catheter. The prosthetic valve device includes a valve operably connected to a support structure. The vascular conduit is supported with the conduit support.

Claims

1. A vascular valve replacement system, the system comprising:

a vascular conduit having a long axis and a lumen communicating therethrough;

a conduit support operably connected to the vascular conduit to reinforce the vascular conduit along the length of the vascular conduit;

the conduit support comprising a substantially circular cross-section and wherein the conduit support comprises a braided structure interwoven with the vascular conduit, and wherein the vascular conduit comprises a woven polyester fabric; and

a prosthetic valve device including a valve operably connected to a support structure, the prosthetic valve device positioned within the vascular conduit adjacent to the conduit support.

2. The system of claim 1 wherein the prosthetic valve device is deployed within the lumen of the vascular conduit with a delivery catheter.

3. The system of claim 1 wherein the conduit support provides reinforcement to the vascular conduit in a radial direction.

4. The system of claim 1 wherein the support structure comprises an expandable stent for retaining the prosthetic valve device within the vascular conduit.

5. A pulmonary valve replacement system comprising:

a delivery catheter;

an inflatable member operably attached to the catheter;

a vascular conduit having a long axis and a lumen communicating therethrough;

a conduit support operably connected to the vascular conduit to reinforce the vascular conduit along the length of the vascular conduit;

the conduit support comprising a substantially circular cross-section and wherein the conduit support comprises a braided structure interwoven with the vascular conduit, and wherein the vascular conduit comprises a woven polyester fabric; and

a prosthetic valve device including a valve operably connected to a support structure, the prosthetic valve device disposed on the inflatable member for delivery to the vascular conduit.

6. The system of claim 5 wherein the conduit support provides reinforcement to the vascular conduit in a radial direction.

7. The system of claim 5 wherein the support structure comprises an expandable stent for retaining the prosthetic valve device within the vascular conduit.

8. A method for replacing a pulmonary valve, the method comprising:

providing a vascular conduit positioned at a treatment site, the vascular conduit having a long axis and a lumen communicating therethrough and the vascular conduit further including a conduit support positioned within the vascular conduit wherein the conduit support comprises a braid structure interwoven with the vascular conduit;

supporting the vascular conduit with the conduit support; and

deploying a prosthetic valve device within the vascular conduit via a delivery catheter, the prosthetic valve device including a valve operably connected to a support structure.

9. The method of claim 8 wherein the conduit support comprises nitinol.

10. The method of claim 8 wherein supporting the vascular conduit comprises reinforcing the vascular conduit in a radial direction.

11. The method of claim 8 further comprising retaining the prosthetic valve device within the vascular conduit.
