Abstract: One method of implanting a prosthetic valve includes advancing the valve into a patient with a delivery apparatus. The valve includes apices circumferentially-spaced apart relative to each other. At least some of the apices include first apertures. The delivery apparatus includes release arms and a sheath. The release arms include second apertures for receiving the apices. At least one of the second apertures of the release arms has a different length than another one of the second apertures. The method also includes positioning the valve at a location, retracting a sheath of the delivery apparatus relative to the valve, allowing the valve to self-expand from a radially compressed state to a radially expanded state, and while the valve is coupled to the delivery apparatus, pivoting the valve relative about the release arms such that an axis of the valve is tilted relative to an axis of the delivery apparatus.

Abstract: Method for delivering an expandable member to a treatment location includes an elongate shaft and an expandable member coupled to a distal end of the elongate shaft. Embodiments of the expandable member are moveable between a collapsed configuration and an expanded configuration, and have an inner expandable member and a plurality of outer expandable members that at least partially surround the inner expandable member, and are suitable for delivering prosthetic heart valves and performing vavuloplasties.

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 from the compressed configuration to an expanded configuration. The expansion device includes an inner expandable member and a plurality of outer expandable members. The outer expandable members are distributed such that there are gaps providing perfusion passageways between the expansion device and the prosthetic heart valve when the expansion device is in the expanded configuration.

Abstract: A prosthetic implant delivery assembly can include a prosthetic implant and an elongate catheter. The prosthetic implant can include an expandable stent portion having a longitudinal axis extending from a first end portion of the stent to a second end portion of the stent. The catheter can include a longitudinal axis extending from a proximal end portion of the catheter to a distal end portion of the catheter and a plurality of arms extending axially from the distal end of the catheter. The first end portion of the stent can be releasably and pivotably coupled to at least one the arms of the catheter such that the stent can pivot about the at least one of the arms so that the longitudinal axis of the stent is tilted relative to the longitudinal axis of the catheter.

Abstract: A prosthetic implant delivery assembly includes a prosthetic implant and a catheter. The prosthetic implant includes a plurality of apices with apertures. Each apex of the plurality of apices is circumferentially-spaced apart relative to an adjacent apex. The catheter includes a plurality of arms and a plurality of locking elements. Each of the arms includes an opening configured to receive a respective apex of the prosthetic implant. Each of the locking elements is configured to extend through the aperture of a respective apex of the prosthetic implant. A length of at least one of the locking elements is different than a length of another locking element such that when the prosthetic implant is coupled to the catheter by the locking elements, a longitudinal axis of the prosthetic implant can be held at a tilted position relative to a longitudinal axis of the catheter.
