1. A method of implanting a prosthetic heart valve, the method comprising:
advancing a distal end portion of a catheter shaft through a patient's vasculature, wherein the distal end portion of the catheter shaft comprises an expansion device, and wherein a prosthetic heart valve is mounted on the expansion device, the expansion device and the prosthetic heart valve being in a compressed configuration;
positioning the distal end portion of the catheter shaft and the prosthetic heart valve at or adjacent an implantation location; and
expanding the prosthetic heart valve and the expansion device from the compressed configuration to an expanded configuration, wherein the expansion device comprises a plurality of inner inflatable members and a plurality of outer inflatable members, wherein each inner inflatable member is separately inflatable relative to at least one other inner inflatable member of the plurality of inner inflatable members, wherein one or more outer inflatable members of the plurality of outer inflatable members is separately inflatable relative to at least one or more other outer inflatable members of the plurality of outer inflatable members, and wherein the outer inflatable members are distributed circumferentially around the inner inflatable members and are circumferentially spaced apart relative to each such that there are gaps between adjacent outer inflatable members providing perfusion passageways between the expansion device and the prosthetic heart valve when the expansion device is in the expanded configuration.
