VENTRICULAR ASSIST DEVICE FOR INTRAVENTRICULAR PLACEMENT

摘要

The present invention includes various devices and methods for ventricular assist. In one embodiment, the present invention is a ventricular assist device for intraventricular placement inside a heart of a mammalian subject, the device including a ring configured to be mounted adjacent an apex of the patient's heart; a rigid elongate member having a proximal and distal end; and a pump having a housing and an outflow cannula having a tip, the tip having a distal end projecting through an aortic valve of the subject's heart, wherein the ring and the pump are connected to the rigid elongate member remote from one another so that the rigid elongate member maintains the pump in position relative to the ring.
