Abstract
A medical device for treating a heart valve insufficiency, with an endoprosthesis which can be introduced into a patient's body and expanded to secure a heart valve prosthesis in the patient's aorta. In an embodiment, the endoprosthesis has a plurality of positioning arches configured to be positioned with respect to a patient's aorta and a plurality of retaining arches to support a heart valve prosthesis. The endoprosthesis includes a first collapsed mode during the process of introducing it into the patient's body and a second expanded mode when it is implanted.
Claims20
An endoprosthesis comprising:
- a plurality of first arches configured to be respectively positioned within a plurality of pockets of a native heart valve on a first side of a plurality of native valve leaflets, each first arch having an apex oriented in a first direction and an open end joined to an open end of an adjacent first arch;
- a plurality of second arches configured to be positioned on a second side of the plurality of native valve leaflets, wherein the second side of the plurality of native leaflets is opposed to the first side of the plurality of native leaflets, such that the plurality of native valve leaflets are positioned radially inward of at least a portion of the plurality of first arches and radially outward of at least a portion of the plurality of second arches when the endoprosthesis is implanted;
- a prosthetic valve disposed within an interior of the endoprosthesis;
- and
- a fixing eye disposed between two mutually adjacent first arches of the plurality of first arches,
- wherein the plurality of first arches are self-expandable independently of the plurality of second arches.

An endoprosthesis comprising:
- a plurality of first arches configured to be respectively positioned within a plurality of pockets of a native heart valve on a first side of a plurality of native valve leaflets, each first arch having a U-shaped or V-shaped apex oriented in a first direction and an open end joined to an open end of an adjacent first arch;
- a plurality of second arches configured to be positioned on a second side of the plurality of native valve leaflets, such that the plurality of native valve leaflets are positioned radially inward of at least a portion of the plurality of first arches and radially outward of at least a portion of the plurality of second arches when the endoprosthesis is implanted;
- a prosthetic valve disposed within an interior of the endoprosthesis;
- and
- a fixing eye disposed between two mutually adjacent first arches of the plurality of first arches,
- wherein the first plurality of arches and the second plurality of arches are on opposing sides of the native leaflets, and
- wherein the plurality of first arches and the plurality of second arches each comprise a shape memory material, the plurality of first arches being self-expandable independently of the plurality of second arches.

An endoprosthesis comprising:
- a plurality of first arches configured to be respectively positioned within a plurality of pockets of a native heart valve on a first side of a plurality of native valve leaflets, each first arch having an apex oriented in a first direction and an open end joined to an open end of an adjacent first arch;
- a plurality of second arches configured to be positioned on a second side of the plurality of native valve leaflets, wherein the first plurality of arches and the second plurality of arches are on opposing sides of the native leaflets, such that the plurality of native valve leaflets are positioned radially inward of at least a portion of the plurality of first arches and radially outward of at least a portion of the plurality of second arches when the endoprosthesis is implanted;
- a prosthetic valve disposed within an interior of the endoprosthesis;
- and
- a fixing eye disposed between two mutually adjacent first arches of the plurality of first arches,
- wherein the plurality of first arches is coupled to the plurality of second arches, and
- wherein the plurality of first arches are self-expandable independently of the plurality of second arches.
