Prosthetic heart valve devices and associated systems and methods
First Claim
1. A prosthetic heart valve device for treating a native heart valve having a native annulus and native leaflets, comprising:
- an expandable frame comprising a first portion having a downstream region and an upstream region and a second portion extending outwardly from the downstream region of the first portion in an upstream direction when the frame is in an expanded configuration;
a valve member attached to an interior of the first portion;
and a skirt coupled to the downstream region of the first portion and flaring outwardly in the upstream direction separate from the second portion such that an upstream region of the skirt is spaced outwardly from the first portion and inwardly from the second portion, wherein the skirt extends around the entire circumference of the first portion.

Abstract
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.

16. A prosthetic heart valve device for treating a native heart valve having a native annulus and native leaflets, comprising:
-
an expandable frame comprising a first portion having a downstream region, an upstream region and a circular cross-section, a second portion extending outwardly from the downstream region of the first portion in an upstream direction when the frame is in an expanded configuration, and a third portion extending outwardly from the upstream region of the first portion in a downstream direction when the frame is in an expanded configuration; a valve member attached to the first portion; and a skirt coupled to the downstream region of the first portion and flaring outwardly in the upstream direction separate from the second portion such that an upstream region of the skirt is spaced outwardly from the first portion and inwardly from the second portion, wherein the skirt extends around the entire circumference of the first portion, and wherein the frame is configured to receive native heart valve leaflets between the first and second portions of the frame when the frame is in an expanded configuration.
