Abstract
A heart valve prosthesis can have a valve anchor with at least one U-shaped member extending about a longitudinal axis of the valve anchor. The U-shaped member can have a peak portion and a base portion. The peak portion can have an engagement structure that allows a surgeon to engage the valve anchor with a delivery device and manipulate a position of the valve anchor in situ in order to achieve optimal placement of the prosthesis at a target site within a patient.
Claims20
A valve prosthesis configured to be positioned within a native heart valve, the valve prosthesis comprising:
- a valve anchor having a plurality of U-shaped members that are interconnected at respective peak portions of the U-shaped members, each of the U-shaped members comprising a base portion configured to fit inside a sinus of the native heart valve and an engagement structure extending from the base portion;
- an expandable valve frame having a compressed configuration, an expanded configuration, and first and second end portions, the expandable valve frame being configured to expand within the valve anchor;
- and
- a link mechanism interconnecting the valve anchor with the expandable valve frame.
A method for delivering a heart valve prosthesis to a native heart valve of a patient, the method comprising:
- permitting expansion of a valve anchor at the native heart valve, the valve anchor having a plurality of U-shaped members that are interconnected at respective peak portions thereof, each of the U-shaped members comprising a base portion that is positioned within a sinus of the native heart valve and an engagement structure extending from the base portion;
- manipulating a longitudinal or rotational position of the valve anchor using one or more graspers coupled to the engagement structures of the valve anchor for urging the valve anchor into engagement with the native heart valve;
- and
- disengaging each engagement structure from the one or more graspers to release the base portions of the valve anchor.
