Abstract: A connection assembly generally comprising a thick conductor piece including a receptacle with an inner wall and a thin conductor piece. The thin conductor piece has a protrusion for insertion into the receptacle. A press-fit element can be inserted into the receptacle with the protrusion arranged in the receptacle between the press-fit element and the thick conductor piece.

Abstract: A multi-chamber ventricular assist device (VAD) for blood pumping includes a rigid outer housing having an inlet and outlet, a pre-filling chamber disposed within the housing fluidly connected to the inlet, and an a ejection chamber disposed within the outer housing. A movable plate is flexibly secured to the housing and is in a flow path of the blood being disposed between the pre-filling and the ejection chamber. The movable plate has a one-way valve for flowing blood from said pre-filling chamber to the ejection chamber. An outlet valve is disposed between the ejection chamber and the outlet of the device. A structure is provided for moving the movable plate. The multi-chamber VAD is suitable as a heart prosthesis which can be implanted in the body or used externally.

Abstract: A process for producing a thin film magnetic head uses the upper magnetic pole as a self-aligning mask for partially trimming the lower magnetic pole, wherein the yoke and pole tip regions to be trimmed are processed by separate and distinct photolithographic steps, thereby achieving noncritical alignment in the yoke area, while maintaining critical alignment in the pole tip region which includes the transducing gap.
