Abstract: In various examples, a component is for use in an implantable medical device. The component includes a pin including a first material attached to a lead including a second material different from the first material of the pin. At least a portion of the lead includes a channel in which at least a portion of the pin sits, the channel including a channel opening defined at least partially by opposing first and second channel sides extending a channel length. At least a first joint is formed along at least a portion of the first channel side. The first joint includes the second material of the lead deformed to at least partially close the channel opening to retain the pin within the channel to attach the lead to the pin. In some examples, the first material includes molybdenum and the second material includes aluminum.

Abstract: An electrochemical cell has a cylindrically-shaped casing tube with at least first and second lithium sheets swaged onto its inner surface. The first lithium sheet has respective spaced apart first right and left edges, and the second lithium sheet has spaced apart second right and left edges. The first and second right edges and the first and second left edges of the swaged first and second lithium sheets are adjacent to but spaced apart from each other by about 0.5° to about 1° about the inner circumference of the cylindrically-shaped casing tube. A novel process for swaging the first and second lithium sheets onto the inner surface of the casing tube is also described.

Abstract: A pulse dischargeable electrochemical cell, preferably of a Li/SVO couple, is described. To help prevent lithium clusters from bridging to the terminal pin extending below the casing lid and connected to the cathode current collector tab, an elastomeric gasket directly contacts the inner surface of the lid. The elastomeric gasket is preferably a unitary member comprising an O-ring gasket portion that contacts the sealing glass of the glass-to-metal seal (GTMS), and a sheet-shaped gasket portion connected to the O-ring gasket portion and that contacts the inner surface of the lid. The GTMS does not have a ferrule. Instead, the sealing glass seals directly to the lid and to the terminal pin. The elastomeric gasket resides between the lid and an insulator compartment, which is described in co-assigned U.S. Pat. No. 10,629,862 to Roy et al.
