Patent ID: 11235137

Abstract:
Methods and devices for implanting a ventricular assist device employ a coupler that engages an aperture formed in a heart wall and provides a conduit by which blood is pumped from the ventricle via the ventricular assist device. A method includes penetrating a distal end of a delivery device through a wall of a heart into a ventricle of the heart to form an aperture having a diameter in the wall. A coupler is deployed from the delivery device so that the coupler engages the aperture, expands the diameter of the aperture, and forms a conduit for a flow of blood from the ventricle. The delivery device is removed from the ventricle by retracting the delivery device through the conduit. The ventricular assist device is coupled to the coupler to receive the flow of blood from the ventricle and pump the flow of blood to assist circulation in the patient.
