Prosthetic heart valve device and associated systems and methods
First Claim
1. A prosthetic heart valve device for treating a native valve of a human heart having a native annulus and native leaflets, comprising:
- a valve support having an inflow region and an outflow region;
a prosthetic valve assembly within the valve support; and
an anchoring member having a base attached to the outflow region of the valve support, a plurality of arms projecting laterally outward from the base and inclined in an upstream direction in a deployed state, and a fixation structure extending upstream from the arms, the fixation structure having a plurality of struts that define an annular engagement surface configured to press outwardly against the native annulus and a plurality of fixation elements projecting from the struts, wherein a downstream-most portion of the fixation structure extends from the arms at a smooth bend, and all of the fixation elements projecting from the fixation structure extend in an upstream direction, and wherein the plurality of arms, the plurality of struts, and the plurality of fixation elements are configured to be partially deployed from a capsule and then at least substantially recaptured within the capsule by moving at least one of the capsule and/or the device relative to the other such the plurality of arms, the plurality of struts, and the plurality of fixation elements slide into the capsule.

Abstract
The present technology is a prosthetic heart valve device, and related systems and methods, for treating a native valve of a human heart having a native annulus and native leaflets. One embodiment comprises a valve support having an inflow region and an outflow region, and a prosthetic valve assembly within the valve support. The device further includes an anchoring member having a base attached to the outflow region of the valve support, a plurality of arms projecting laterally outward from the base and inclined in an upstream direction in a deployed state, and a fixation structure extending upstream from the arms. The fixation structure has a plurality of struts that define an annular engagement surface configured to press outwardly against the native annulus and a plurality of fixation elements projecting from the struts. The downstream-most portion of the fixation structure extends from the arms at a smooth bend, and fixation elements at the downstream-most portion of the fixation structure extend in an upstream direction.

11. A prosthetic heart valve device for treating a native valve of a human heart having a native annulus and native leaflets, comprising:
-
an annular inner support frame having an inflow region and an outflow region; a prosthetic valve assembly within the inner support frame; and an anchoring member having a base attached to the outflow region of the inner support frame, a plurality of arms projecting laterally outward from the base at an angle inclined in an upstream direction, an outer fixation frame extending upstream from the arms, and fixation elements projecting from the outer fixation frame, and wherein all of the fixation elements project from the outer fixation frame extend in an upstream direction, the outer fixation frame having a plurality of struts that define an annular engagement surface spaced radially outward from the inflow region of the inner support frame in the deployed state, wherein the arms and the struts are configured to be partially deployed from a capsule and then at least substantially recaptured within the capsule by moving at least one of the capsule and/or the device relative to the other such the arms and struts slide into the capsule. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)

20. A valve support for a prosthetic heart valve, comprising:
-
a first row of first hexagonal cells at an outflow region of the valve support, wherein the first hexagonal cells have first longitudinal supports, first and second upstream struts extending upstream from the first longitudinal supports, and first and second downstream struts extending downstream from the first longitudinal supports; a second row of second hexagonal cells at an inflow region of the valve support, wherein the second hexagonal cells have second longitudinal supports, first and second upstream struts extending upstream from the second longitudinal supports, and first and second downstream struts extending downstream from the second longitudinal supports; and wherein the first and second upstream struts of the first hexagonal cells and the first and second downstream struts of the second hexagonal cells are the same struts. - View Dependent Claims (21, 22, 23, 24, 25)
