Abstract
A prosthetic valve assembly for use in replacing a deficient native valve comprises a replacement valve supported on an expandable valve support. The valve support, which entirely supports the valve annulus, valve leaflets, and valve commissure points, is configured to be collapsible for transluminal delivery and expandable contact the anatomical annulus of the native valve when the assembly is properly positioned. Portions of the valve support may expand to a preset diameter to maintain coaptivity of the replacement valve and to prevent occlusion of the coronary ostia.
Claims20
A method for implanting a prosthetic cardiac valve comprising:
- inserting a prosthetic cardiac valve into a body lumen, the prosthetic cardiac valve comprising:
- a replacement valve comprising:
- a plurality of leaflets configured to permit blood to selectively flow therethrough;
- and
- a plurality of commissure points from which the replacement valve is suspended;
- and
- a valve support connected to the replacement valve and configured to be collapsible for transluminal delivery, comprising:
- a first section terminating in a first end, the first end comprising an outer circumference having a first diameter, the first section configured to engage a native valve annulus;
- and
- a second section terminating in a second end, the second end comprising an outer circumference having a second diameter, the second section configured to extend past the coronary ostia and into the ascending aorta,
- wherein the second circumference is greater than the first circumference,
- and wherein the valve support has an axial length sufficient to extend, when implanted, from the native valve annulus, past the replacement valve, past the commissure points, past a patient's coronary ostia, and into an ascending aorta;
- positioning the prosthetic cardiac valve such that the valve support extends from the native annulus past the coronary ostia and into the ascending aorta;
- and
- deploying the prosthetic cardiac valve.
A method for implanting a prosthetic cardiac valve comprising:
- inserting a prosthetic cardiac valve into a body lumen, the prosthetic cardiac valve comprising:
- a collapsible valve support;
- and
- a plurality of leaflets connected to an interior of the valve support,
- wherein the valve support has an axial length greater than a length from a patient's native valve annulus to the patient's coronary ostia;
- positioning the prosthetic cardiac valve such that the valve support extends from the native annulus past the coronary ostia and into the patient's ascending aorta;
- and
- deploying the prosthetic cardiac valve.
A method for replacing a native cardiac valve comprising:
- loading a prosthetic cardiac valve onto a delivery system, the prosthetic cardiac valve comprising:
- a collapsible valve support;
- and
- a plurality of leaflets connected to an interior of the valve support,
- wherein the valve support has an axial length greater than a length from a patient's native valve annulus to the patient's coronary ostia;
- covering the prosthetic cardiac valve with a sheath;
- inserting the delivery system into a body lumen;
- advancing the delivery system through the body lumen to an implantation location within the patient's heart;
- positioning the prosthetic cardiac valve such that the valve support extends from the native annulus past the coronary ostia and into the patient's ascending aorta;
- deploying the prosthetic cardiac valve;
- and
- removing the delivery system from the body lumen.
