Abstract
A method of implanting a prosthetic heart valve includes advancing a distal end portion of a catheter shaft through a patient's vasculature. The distal end portion of the catheter shaft includes an expansion device. A prosthetic heart valve is mounted on the expansion device with the expansion device and the prosthetic heart valve in a compressed configuration. The method further includes positioning the distal end portion of the catheter shaft and the prosthetic heart valve to an implantation location and expanding the prosthetic heart valve and the expansion device to an expanded configuration. The expansion device includes a main body and a plurality of projections extending radially from the main body. The projections are spaced apart relative to each such that there are grooves extending between adjacent projections providing perfusion passageways between the expansion device and the prosthetic heart valve when the expansion device is in the expanded configuration.
