A method for manufacturing a ceramic substrate by a 3D-printing process is described. The method comprises operating a 3D-printer to print a green-state ceramic body having a height extending to spaced apart first and second end surfaces and at least one via extending at least part-way along the height of the green-state ceramic body from the first end surface toward the second end surface. Then, the green-state ceramic body is sintered to provide the ceramic substrate with the at least one via. In cross-section, the at least one via has a square-shaped via with rounded corners.

A sealing device for sealing a current-carrying element on an electrical drive system. The sealing device includes an elastic form sealing unit for insulating the current-carrying element against at least a part region of the electrical drive. The sealing device also includes a non-elastic guide sealing unit for guiding the current-carrying element, wherein the form sealing unit and the guide sealing unit are formed to engage in one another at least partially by form fit in operational state.

Disclosed herein is an implantable pulse generator for administering electrotherapy via an implantable lead. The pulse generator includes a housing and a header connector assembly coupled to the housing. The header connector assembly includes a connector assembly and a header enclosing the connector assembly. The connector assembly includes a support and a connector receptacle. The support extends at least partially about the connector receptacle and is at least partially responsible for having prevented injection molding material from entering the connector receptacle when the injection molding material was injection molded about the connector assembly in forming the header.

A ceramic subassembly manufactured by a 3D-printing process is described. The ceramic subassembly comprises a ceramic substrate having a sidewall extending to spaced apart first and second end surfaces. At least one via extends through the substrate from the ceramic substrate first end surface to the ceramic substrate second end surface. In cross-section, the via has a square-shape with rounded corners.

A wire harness includes an electric wire, a braided conductor covering the electric wire, a grommet having a tubular insertion portion through which the electric wire and the braided conductor are inserted, a water stop sheet sandwiched between an inner peripheral surface of the insertion portion and the braided conductor, and a fixture attached to the insertion portion so as to reduce a diameter of the insertion portion. The water stop sheet includes a base material layer having a plurality of pores communicating with each other in a thickness direction of the water stop sheet and a sealing compound layer laminated on the base material layer. The sealing compound layer is deformed so as to enter gaps between thin conductor wires constituting the braided conductor and the pores of the base material layer.
