Devices useful for implantation at a heart valve
First Claim
1. A device useful for implantation at a native heart valve, the device comprising:
- an anchor element having a tubular configuration defining a longitudinal direction and a circumference;
a heart valve prosthesis disposed within the anchor element; and
a plurality of elongate members positioned at equidistant angular intervals about the circumference of the anchor element,wherein the device is configured to be transitioned from a radially collapsed delivery configuration to a radially expanded implantation configuration, andwherein the plurality of elongate members have a length extending in the longitudinal direction of the tubular anchor element in the expanded implantation configuration.

Abstract
A device useful for implantation at a native heart valve can include an anchor element having a tubular configuration defining a longitudinal direction and a circumference, a heart valve prosthesis disposed within the anchor element, and a plurality of elongate members positioned at equidistant angular intervals about the circumference of the anchor element. The device can be configured to be transitioned from a radially collapsed delivery configuration to a radially expanded implantation configuration, and the plurality of elongate members can have a length extending in the longitudinal direction of the tubular member in the expanded implantation configuration.

22. A device for implantation at a native heart valve, the device comprising:
-
an anchor element having a tubular configuration and defining a longitudinal direction and circumference; a heart valve prosthesis disposed within the anchor element; three elongate members attached to a lateral wall of the anchor element and positioned at equidistant angular intervals about the circumference of the anchor element; an impermeable casing disposed adjacent to the anchor element; wherein the device is configured to be in a radially collapsed delivery configuration for endovascular delivery to the native heart valve, wherein the device is configured to be transitioned from the radially collapsed delivery configuration to a partially radially expanded configuration, and then to a radially expanded implantation configuration, the partially radially expanded configuration differing from the radially expanded implantation configuration, wherein, in the radially expanded implantation configuration of the device; the elongate members have a length extending in the longitudinal direction of the tubular anchor element, and the impermeable casing is configured to be positioned to inhibit blood flow between the impermeable casing and heart tissue. - View Dependent Claims (23, 24, 25)
