Prosthetic leaflet assembly for repairing a defective cardiac valve and methods of using the same

摘要

Methods and apparatus are provided for repairing or replacing a defective cardiac valve including a prosthetic leaflet assembly having an expandable frame with one or more anchors configured to engage a predetermined region of the defective cardiac valve in an expanded deployed state, and at least one prosthetic leaflet coupled to the expandable frame. The prosthetic leaflet assembly is configured such that the prosthetic leaflet is suspended within a flow path of the defective cardiac valve and coapts with, and improves functioning of, one or more native leaflets of the defective cardiac valve.

主权项

1. A prosthetic leaflet assembly for repairing a defective cardiac valve having two or more native leaflets defining a flow path through a central opening of the defective cardiac valve, the prosthetic leaflet assembly comprising:
an expandable frame configured to transition from a contracted delivery state to an expanded deployed state, the expandable frame having one or more anchors configured to engage a predetermined region of the defective cardiac valve in the expanded deployed state; and one or more prosthetic leaflets coupled to the expandable frame, the one or more prosthetic leaflets configured to be suspended within the flow path and to occupy a portion of the central opening such that the one or more prosthetic leaflets coapt with, and improve functioning of, the two or more native leaflets.
