Prosthetic heart valve devices and associated systems and methods

摘要

Prosthetic heart valve devices for percutaneous replacement of native heart valves and associated systems and method are disclosed herein. A prosthetic heart valve device configured in accordance with a particular embodiment of the present technology can include an expandable support having an outer surface and configured for placement between leaflets of the native valve. The device can also include a plurality of asymmetrically arranged arms coupled to the expandable support and configured to receive the leaflets of the native valve between the arms and the outer surface. In some embodiments, the arms can include tip portions for engaging a subannular surface of the native valve.

主权项

1. A prosthetic treatment apparatus for treating a native mitral valve having a native annulus and native leaflets, comprising:
a support having a downstream end configured to be positioned toward a left ventricle and an upstream end configured to be positioned toward a left atrium, wherein the support is expandable from a low-profile configuration for implantation to an expanded configuration at the native mitral valve; a prosthetic valve attached to the support; a plurality of elongated members extending outwardly from a downstream portion of the support in an upstream direction, wherein
the elongated members are configured to remain inward of an inner surface of the native leaflets, andthe elongated members are biased outwardly in the expanded configuration to exert force against the inner surface of the native leaflets; and a skirt coupled to the downstream portion of the support and flaring outward in an upstream direction such that an upstream end of the skirt is spaced outwardly from the support, wherein the skirt extends around the entire circumference of the support.
