Abstract: A prosthetic heart valve for implantation within a native atrioventricular heart valve. The prosthetic heart valve includes a self-expanding frame having an annular main body and a valve member disposed within the main body. The prosthetic heart valve includes an atrial sealing member formed by a fabric cover and a plurality of arms that are arranged side-by-side in a circumferential direction around the main body. The atrial sealing member extends radially outwardly from the main body and a peripheral portion of the atrial sealing member curves upwardly for conforming to surrounding native anatomy. The prosthetic heart valve further includes one or more ventricular anchors extending from the main body for capturing native leaflet tissue and thereby securing the prosthetic heart valve within the native atrioventricular heart valve.

Abstract: Embodiments of prosthetic valves for implantation within a native mitral valve are provided. One embodiment of a prosthetic valve includes a radially compressible main body and a one-way valve member. In some cases, the prosthetic valves also include ventricular anchors and/or an atrial portion coupled to and disposed outside of the main body. Methods, devices, and systems for delivering such prosthetic valves to the native mitral valve and implanting them therein are also provided.

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 delivery cylinder for a prosthetic implant can include a first tubular portion and a second tubular portion. The second tubular portion has a plurality of strut members coupled to the first tubular portion that define a volume for containing the prosthetic implant in a radially compressed state. The strut members can include respective flex regions configured such that application of force to the strut members causes deformation of the flex regions and corresponding radially inward or outward movement of the strut members relative to a longitudinal axis of the delivery cylinder between an expanded configuration and a contracted configuration.

Abstract: A valve catheter is advanced through a patient's vasculature while a prosthetic heart valve is attached to flexible extensions along a distal end thereof. The valve catheter is advanced through a tubular sleeve for exposing the prosthetic heart valve and allowing the prosthetic heart valve to self-expand while the extensions remain attached to the prosthetic heart valve. A release mechanism on a handle portion is actuated for releasing the prosthetic heart valve from the extensions, thereby implanting the prosthetic heart in a native heart valve. If the operator is not satisfied with the initial expansion, the prosthetic heart valve may be reoriented before release from the extensions by retracting the prosthetic heart valve back into the tubular sleeve, adjusting the orientation of the prosthetic heart valve and then re-advancing the valve catheter from the tubular sleeve for allowing the prosthetic heart valve to re-self-expand at a more desirable location.
