Abstract
A method and device for treating mitral regurgitation includes providing a treatment device comprising an expandable frame, and a leaflet assembly housed inside the frame. The frame has a tenting element. The treatment device is delivered to the aortic position in a patient's aortic valve, and the frame is expanded at the location of the native aortic valve, with the tenting element pushing the aortic curtain and/or anterior leaflet and/or mitral annulus of the mitral valve towards the mitral valve direction. The leaflet assembly replaces the valve function of the patient's native aortic valve.
Claims21
A method for treating mitral regurgitation, comprising the steps of:
- providing a treatment device comprising an expandable frame, and a leaflet assembly housed inside the frame, the frame having a tenting element;
- delivering the treatment device to the aortic position in a patient's aortic valve;
- and
- expanding the frame at the location of the native aortic valve to push aside and cover the patient's native aortic valve, with the tenting element pushing the anterior leaflet of the mitral valve towards the mitral valve direction or to reshape the mitral annulus, whereby the leaflet assembly replaces the valve function of the patient's native aortic valve.
An aortic valve device, comprising:
- a frame having an annulus support, an aortic flange extending from one end of the annulus support, and a ventricular flange extending from another end of the annulus support, the ventricular flange flared radially outwardly so that the ventricular flange gradually increases in diameter until it reaches a ventricular end;
- the frame further including a tenting element that extends from a portion of the circumference of the ventricular end that is less than 90% of the circumference of the ventricular end, with the tenting element defining one or more cellular elements that are formed by struts that are connected to the ventricular end, with the tenting element located at a side of the circumference of the ventricular end that is positioned closer to a patient's aortic curtain when the frame is implanted in the aortic portion;
- and
- a set of leaflets sutured into the interior of the frame.
An aortic valve device that is implanted at the location of a patient's native aortic valve to treat mitral regurgitation, comprising:
- a frame having an annulus support, an aortic flange extending from one end of the annulus support, and a ventricular flange extending from another end of the annulus support, the ventricular flange flared radially outwardly so that the ventricular flange gradually increases in diameter until it reaches a ventricular end;
- the frame further including a tenting element that extends from a portion of the circumference of the ventricular end that is less than 90% of the circumference of the ventricular end, with the tenting element defining one or more cellular elements that are formed by struts that are connected to the ventricular end, with the tenting element located at a side of the circumference of the ventricular end that is positioned closer to a patient's aortic curtain when the frame is implanted in the aortic portion so that the tenting element pushes the anterior leaflet of the mitral valve toward the mitral valve direction;
- and
- a set of leaflets sutured into the interior of the frame, with the leaflets assuming the valve function of the patient's native aortic valve.
