    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: An isolated, multipoint connection for a coiled electrode electrochemical cell which includes a cathode assembly with a cathode current collector having at least two connector tabs spaced apart on an edge of the current collector and an anode assembly having at least two connector tabs spaced apart on the edge of the anode assembly. Three barriers of nonconductive material are established to isolate the various components; a first nonconductive barrier which isolates the connector tabs from the remainder of the winding; a second nonconductive barrier which isolates the feedthrough and feedthrough pin from the case and from the anode elements; and a third nonconductive barrier established to separate the connections to the cathode connector tabs from the anode elements and from the case.
