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.
Claims25
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, and
- wherein the plurality of elongate members have a length extending in the longitudinal direction of the tubular anchor element in the expanded implantation configuration.
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.
