    摘要： A high rate battery having a coiled electrode assembly housed in a case that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery case provides a planar surface opposite an arcuate surface to allow for the close abutting of other components located within the implantable device while also providing for efficient location of the battery within an arcuate edge of the device. The battery cases include at least three planar sides extending between a top and a base of the battery case, wherein the arcuate side is located directly opposite one of the planar sides. The battery case may form a prismatic solid shape with one arcuate surface and five planar surfaces. The batteries may include a coiled electrode assembly including an anode and a cathode; electrolyte; and a case liner containing the electrode assembly. The coiled electrode assembly can have an elliptical cross-section including two arcuate ends, wherein one of the arcuate ends is nested within an arcuate side of the case. The batteries are capable of delivering about 20 joules or more in about 20 seconds or less; and may also be capable of delivering about 20 joules or more at least twice in a period of about 30 seconds. Also included are implantable defibrillator devices incorporating the batteries and methods of manufacturing the batteries including drawing the battery case from metal.

    摘要： A feedthrough pin insulator and corresponding assembly for an electrochemical cell powering an implantable medical device are described herein. The feedthrough pin insulator electrically insulates a feedthrough pin extending between the internal and external portions of the cell from cell components having the same electrical potential as a cathode disposed within the cell. The feedthrough pin insulator extends between an anode disposed within the cell and a ferrule disposed in an aperture of a cover for sealing the cell. A gate or dam is disposed at one end of the insulator for preventing or inhibiting the formation of anode flash on the feedthrough pin or in other undesired locations or on certain cell components during the anode formation process. A method of forming an anode is also described which corresponds to the foregoing apparatus.
