Artificial heart

摘要

Disclosed herein is a fully implantable artificial heart. The use of flat helical springs to align and reciprocate a bellows structure allows the bellows to pump blood, the multiple solenoids with floating magnetized rods and permanent magnet assemblies held by the flat helical springs provide the power. The artificial heart pumps blood with virtually no friction and no parts to wear out. The use of solenoids advantageously move blood in a gentle, controllable manner.

主权项

1. An artificial heart, comprising:
an outer housing; a solenoid ring comprising at least a first solenoid and a second solenoid; at least one helical spring operably attached at a first end to an axially movable wall and to a second end to the solenoid ring; wherein the helical spring comprises at least a first spring magnet and a second spring magnet spaced apart along a length of the helical spring, the at least first spring magnet and second spring magnet being individually magnetically attractable and repellable with respect to the respective first solenoid and the second solenoid of the solenoid ring, the first solenoid and the second solenoid configured to be energized in series; wherein the helical spring is reversibly movable from a first uncompressed configuration to a second compressed configuration when the first solenoid is energized with a polarity sufficient to attract the first spring magnet into direct contact with the first solenoid.
