Abstract
Highly miniaturized electromechanical medical implants for certain applications cannot be fit into the available anatomic space unless their diameter can be made small enough. With devices such as rotary blood pumps or linear actuators, using rotary or linear electric motors, a thin motor stator that provides sufficient power must be encased in a corrosion resistant hermetically sealed enclosure into which electric wires must pass. Hermetic feedthroughs of the prior art are not structurally suited to maximal miniaturization with optimal electrical properties because of the need for welding of ferrules or other support components. The sub-miniature medical implants having the robust feedthrough of the present invention integrate the feedthrough wires, insulators, and sealing within a radially extending flange that is part of the end wall of the motor enclosure. This permits the largest feedthrough wire and thickest insulator to be built into the limited available space.
