First Claim
Patent Images
1. A ventricular assist device for intraventricular placement inside a heart of a mammalian subject comprising:
- an anchor element configured to be mounted to the subject'"'"'s heart;
a rigid elongate member having proximal and distal ends; and
a pump comprising a housing, an inlet and an outlet, a rotor within the housing and electric drive coils carried on the housing for magnetically driving the rotor,wherein the anchor element and the pump are connected to the elongate member remote from one another,wherein the elongate member includes a bore extending in the proximal and distal direction thereof, the device further comprising wiring extending through the bore to the pump, andwherein the anchor element includes a spherical socket adapted to engage a spherical ball mounted to the elongate member such that the anchor element is pivotally mounted to the elongate member.

Abstract
A ventricular assist device includes a pump such as an axial flow pump, an outflow cannula connected to the outlet of the pump, and an anchor element. The anchor element is physically connected to the pump, as by an elongate element. The pump is implanted within the left ventricle with the outflow cannula projecting through the aortic valve but desirably terminating short of the aortic arch. The anchor element is fixed to the wall of the heart near the apex of the heart so that the anchor element holds the pump and outflow cannula in position.
