Delivery systems for prosthetic heart valve
First Claim
1. A method of implanting a radially compressible and expandable prosthetic heart valve in a native heart valve of the heart, the method comprising:
- introducing a delivery device into the body of a patient, the delivery device comprising a handle portion, an elongated shaft extending from the handle portion, the shaft having a distal end portion mounting an inflatable balloon and a prosthetic heart valve in a radially compressed state;
advancing the distal end portion of the delivery device toward the native heart valve until the prosthetic valve is within or adjacent the annulus of the native heart valve;
positioning the prosthetic heart valve at a desired implantation position within the annulus of the native heart valve;
after the prosthetic heart valve has been moved to the desired implantation position, inflating the balloon to cause the prosthetic heart valve to radially expand and engage the annulus of the native heart valve;
wherein the delivery device comprises a mounting member mounted on the shaft within the balloon; and
wherein when the prosthetic heart valve is being positioned at the desired implantation position, the prosthetic heart valve is mounted on the balloon in the compressed state surrounding the mounting member;
wherein inflating the balloon comprises injecting pressurized inflation fluid into the balloon, which is allowed to flow from a proximal end portion of the balloon, through the mounting member and into a distal end portion of the balloon; and
wherein the inflation fluid follows a fluid flow path that enters the proximal end portion of the balloon outside of the mounting member, then enters a proximal end of the mounting member, travels distally through the mounting member from the proximal end toward a distal end of the mounting member, and then exits through the distal end of the mounting member into space within the distal end portion of the balloon outside of the mounting member, the distal end of the mounting member being located within the distal end portion of the balloon.

Abstract
Described herein are systems and methods from delivering prosthetic devices, such as prosthetic heart valves, through the body and into the heart for implantation therein. The prosthetic devices delivered with the delivery systems disclosed herein are, for example, radially expandable from a radially compressed state mounted on the delivery system to a radially expanded state for implantation using an inflatable balloon of the delivery system. Exemplary delivery routes through the body and into the heart include transfemoral routes, transapical routes, and transaortic routes, among others.
