Claim 12:
13. A delivery device for implantation of a prosthetic heart valve within a heart, the prosthetic heart valve being radially expandable from a radially compressed state to a radially expanded state, the delivery device comprising:
a handle;
a catheter comprising a proximal end portion and a distal end portion, wherein the proximal end portion of the catheter is coupled to the handle, and wherein the distal end portion of the catheter is configured to be inserted into a patient's body;
an inflatable balloon positioned adjacent the distal end portion of the catheter;
an inner shaft extending from the handle and comprising a distal portion positioned within the balloon;
a mounting member fixedly coupled to the distal portion of the inner shaft and disposed within the balloon, wherein the mounting member comprises a first section and a second section, wherein the first section restricts balloon inflation fluid from flowing radially outwardly therethrough, allows the balloon inflation fluid to flow longitudinally through the mounting member, and comprises an at least substantially cylindrical outer surface configured for receiving the prosthetic heart valve in the radially compressed state, wherein the first section is axially longer than the second section and extends axially along at least a majority of an axial length of the prosthetic heart valve when the prosthetic heart valve is mounted over the balloon and the mounting member in the radially compressed state, wherein the second section comprises a fluid pathway between an outer surface of the distal portion of the inner shaft and an inner surface of the mounting member that allows the balloon inflation fluid to flow longitudinally through the prosthetic heart valve when the prosthetic heart valve is mounted over the balloon and the mounting member in the radially compressed state; and
a distal stop at least partially positioned within the balloon and at least partially positioned circumscribing both the distal portion of the inner shaft and the mounting member, the distal stop configured to be positioned adjacent a distal end of the prosthetic heart valve when the prosthetic heart valve is mounted over the balloon and the mounting member in the radially compressed state.
