Delivery systems for prosthetic heart valve

摘要

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.

主权项

1. A delivery device for implantation of a prosthetic device within the body, the prosthetic device being radially expandable from a radially compressed state to a radially expanded state, the delivery device comprising:
an inflatable balloon; and a proximal stop and a distal stop configured to limit longitudinal movement of the prosthetic device relative to the balloon while the prosthetic device is mounted over the balloon in the radially compressed state between the proximal stop and the distal stop; wherein the proximal stop and the distal stop each comprise an end portion positioned within the balloon and configured to be positioned adjacent a respective end of the prosthetic device when the prosthetic device is radially compressed between the proximal and distal stops, each of the end portions comprising at least one longitudinally extending slot that allows the end portion of the respective stop to be radially compressed to a smaller diameter.
