摘要： A feedthrough assembly for an implantable medical device includes a housing, a solid insert, one or more conductive elements, a metal filler, and a non-corrosive sealant. The housing defines a central cavity through a height of the housing. The solid insert is disposed within the central cavity of the housing. The one or more conductive elements extend through one or more apertures defined within the solid insert and extend through the central cavity of the housing. The metal filler is disposed within a joint defined by an outer surface of the solid insert and an inner surface of the housing that defines the central cavity. The non-corrosive sealant coats a top surface of the metal filler to inhibit corrosion of the metal filler.

摘要： A cylindrical battery comprises an electrode body in which a positive electrode and a negative electrode are wound with a separator therebetween, a bottomed cylindrical external can which accommodates the electrode body, and a sealing body which seals an opening of the external can. A bottom part of the external can has a reverse part which has a raised shape such that the reverse part protrudes toward the electrode body in the axial direction and which reverses when the pressure inside the battery reaches a first pressure. The sealing body has a sealing plate which releases gas that is inside the battery by breaking when the pressure inside the battery reaches a second pressure that is higher than the first pressure. The sealing plate functions as a safety valve.
