Total artificial heart

DETAILED DESCRIPTION What is claimed is: 1.
A totally implantable artificial heart comprising: (a) a central housing; (b) a linear electric motor enclosed within the central housing, comprising: (i) a stationary stator; (ii) an armature including a first armature end and a second armature end, the armature linearly movable along a longitudinal axis of the armature in response to an electric current provided to the motor, a linear operation of the electric motor producing thermal energy; (c) a right ventricle cavity forming a selectively variable right ventricle cavity volume for receiving and expelling blood, the right ventricle cavity comprising: (i) a right ventricle housing attached to the central housing; (ii) a first movable wall comprising a first pusher plate attached to the central housing by a first flexible seal and attached to the first armature end such that a linear motion of the armature causes the right ventricle cavity volume to change; (d) a first inlet port including a first inlet valve for allowing blood to enter the right ventricle cavity when the right ventricle cavity volume increases; (e) a first outlet port including a first outlet valve for allowing blood to exit the right ventricle cavity when the right ventricle cavity volume decreases; (f) a left ventricle cavity forming a selectively variable left ventricle cavity volume for receiving and expelling blood, the left ventricle cavity comprising: (i) a left ventricle housing attached to the central housing; (ii) a second movable wall comprising a second pusher plate attached to the central housing by a second flexible seal and attached to the second armature end such that the linear motion of the armature causes the left ventricle cavity volume to change; (g) a second inlet port including a second inlet valve for allowing blood to enter the left ventricle cavity when the left ventricle cavity volume increases; (h) a second outlet port including a second outlet valve for allowing blood to exit the left ventricle cavity when the left ventricle cavity volume decreases; and (i) heat transfer means for simultaneously conducting thermal energy from the electric motor to the first and second pusher plates, to the left and right ventricle housings, to the central housing, to blood that is being pumped through the artificial heart, and to body tissues surrounding the artificial heart
