Centering devices for use with a valve prosthesis delivery system and methods of use thereof
First Claim
1. A method of delivering a valve prosthesis configured for delivery within a vasculature, the method comprising the steps of:
- percutaneously introducing a valve centering catheter into a vasculature, the valve centering catheter having a circumferential centering device at a distal portion thereof, wherein the circumferential centering device is in a delivery configuration;
tracking the valve centering catheter through the vasculature until the circumferential centering device is positioned at a treatment site;
radially expanding the circumferential centering device into an expanded configuration at the treatment site, wherein the circumferential centering device has an outer wall and an inner wall with an interior space being defined between the outer wall and the inner wall, the inner wall defining a central opening there-through when in the expanded configuration;
percutaneously introducing a valve delivery system into the vasculature after the circumferential centering device has been radially expanded, the valve delivery system having a valve prosthesis at a distal portion thereof, wherein the valve prosthesis is in a delivery configuration;
tracking the valve delivery system through the vasculature until the valve prosthesis is positioned through the central opening of the expanded circumferential centering device in order to circumferentially center the valve prosthesis within the native anatomy of the treatment site; and
deploying at least an inflow end of the valve prosthesis into apposition with the native anatomy of the treatment site while at least a portion of the valve prosthesis remains in the delivery configuration and positioned through the central opening of the expanded circumferential centering device, thereby anchoring and securing the circumferentially centered position of the valve prosthesis within the native anatomy of the treatment site.

Abstract
Embodiments hereof relate to centering devices for use with a valve delivery system and methods of delivering a valve prosthesis within a vasculature. A valve centering catheter is configured for use with a valve delivery system. The valve centering catheter includes a circumferential centering device at a distal portion thereof, and the circumferential centering device defines a central opening there-through when in an expanded configuration. The circumferential centering device is annular or has a C-shaped cross-section. The valve delivery system is tracked through the vasculature until the valve prosthesis is positioned through the central opening of the expanded circumferential centering device. The valve centering catheter may alternatively include a longitudinal centering device which acts as a marker for depth control during delivery of a valve delivery system, which may include an integral circumferential centering device.
