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.

Claims16

Dependent claims

A delivery apparatus for implanting a radially compressible and expandable prosthetic heart valve in a native heart valve of the heart, the apparatus comprising:

an elongated shaft comprising a proximal end portion and a distal end portion;
an inflatable balloon mounted on the distal end portion of the shaft;
and
a valve mounting member disposed on the distal end portion of the shaft within the balloon and configured to facilitate frictional engagement between the prosthetic heart valve and the balloon when the prosthetic heart valve is mounted in a radially compressed state on the balloon and surrounding the mounting member, the mounting member comprising at least one longitudinally extending fluid passageway though which an inflation fluid in the balloon can flow, the fluid passageway extending from a proximal end portion to a distal end portion of the mounting member;
wherein inflation fluid outside of the mounting member can flow inwardly through the proximal end portion of the mounting member, into and through the fluid passageway, and then outwardly through the distal end of the mounting member into space within the balloon outside of the mounting member.

A delivery apparatus for implanting a radially compressible and expandable prosthetic heart valve in a native heart valve of the heart, the apparatus comprising:

an elongated shaft comprising a proximal end portion and a distal end portion;
an inflatable balloon mounted on the distal end portion of the shaft;
and
a valve mounting member comprising a coiled wire coaxially disposed on the distal end portion of the shaft within the balloon and configured to facilitate frictional engagement between the prosthetic heart valve and the balloon when the prosthetic heart valve is mounted in a radially compressed state on the balloon and surrounding the coiled wire, the coiled wire comprising a proximal end portion, a distal end portion, and a lumen extending from the proximal end portion to the distal end portion though which an inflation fluid in the balloon can flow;
wherein inflation fluid outside of the coiled wire can flow inwardly through spaces between coils within the proximal end portion of the coiled wire, into and through the lumen, and then outwardly through spaces between coils within the distal end portion of the coiled wire into space within the balloon outside of the coiled wire.
