Abstract: An implantable medical device having opposed major sidewalls of contoured shape closely fits the curved shape of a body. The contoured major sidewalls can have a curved shape of a continuous radius with the major sidewalls deflecting in a similar direction. Alternatively, the major sidewalls can have a curved shape corresponding to more than one radius. The device housing is either deep drawn or includes two clam shells that are secured together.

Abstract: The present invention provides an electrochemical cell of either a primary or a secondary chemistry housed in a casing having opposed major side walls of a contoured shape.

Abstract: A rod-shaped coupler for connecting a current collector to a terminal pin, is described. The coupler is secured to the entire width of the current collector, preferably the cathode in a cell of a case negative design, and is generally aligned along the longitudinal axis of the electrode assembly. An extension portion of the coupler extends beyond the electrode assembly and is of a hollow, tubular structure crimped or otherwise collapsed into surrounding contact with the terminal pin. The coupler and terminal pin are then welded together. Preferably, the terminal pin is roughened prior to effecting the connection. This method of attachment is suitable for either primary lithium or secondary lithium ion cells, particularly those powering implantable biomedical devices.

Abstract: A laryngoscope constructed of materials including metal components having very low magnetic susceptibilities is described. The battery powering the laryngoscope lamp is a lithium battery also constructed of materials having low magnetic susceptibilities. The battery further includes a unique terminal configuration that prevents the inadvertent use of other batteries, including non-magnetic batteries, in the laryngoscope. A unique lamp retaining mechanism provides for quick and easy replacement of the lamp.

Abstract: A spirally-wound electrochemical cell having a resilient member such as a resilient pad or a wave spring disposed between the spirally-wound electrode and separator assembly and at least one of the end walls for resiliently dissipating mechanical forces acting to otherwise cause axial movements of the spirally-wound assembly.
