A hermetic terminal (110) includes a barrier wall (12) to be joined to a housing (11), a body (15) that is to be connected to a signal ground and is fixed to the barrier wall (12) via a first insulator (13), and a signal line (16) passing through the body (15) and fixed to the body (15) via a second insulator (14). When the barrier wall (12) is joined to the housing (11), a space (28) is formed between an inner wall of the housing (11) and a surface (31) of the body (15) intersecting an end face (29) of the body (15) positioned towards the inside of the housing (11).

High voltage insulators are disclosed, along with related methods of manufacture and use. The disclosed high voltage insulators include a core strength member joined to one or more end fittings and secured with one or more elastomeric members. A plastic body surrounds the core strength member, the elastomeric member, and at least a portion of the end fitting. In particular, the plastic body is molded over the elastomeric member(s) and, upon cooling, the plastic body exerts a radial compressive force on the underlying elastomeric member(s) to seal the joint of the high voltage insulator and protect it from moisture, even throughout temperature fluctuations in the field.

A joint joins an alloy member to a ceramic member via a glass joining agent, which is joined to the alloy member by a material bonded joint and to the ceramic member by a further material bonded joint. The glass joining agent is made of a glass having a melting point below 800° C.; a coefficient of thermal expansion of at least 9-10.sup.−6 K.sup.−1 and a bismuth content of at least 10%. The alloy member has a coefficient of thermal expansion of at least 9-10.sup.−6 K.sup.−1. The ceramic member has a maximum coefficient of thermal expansion of 8-10.sup.−6 K.sup.−1. The material bonded joint defines a mixing region that is a partial region of the ceramic member, and the bismuth content in the mixing region is higher than that of the ceramic member outside the mixing region.

A feedthrough assembly may include a feedthrough conductor, a first insulator, and a first metal gasket forming a seal between the feedthrough conductor and the first insulator. The feedthrough assembly may additionally include a body, and a second metal gasket forming a seal between the body and the first insulator. Methods of manufacturing such feedthrough assemblies may include compressing the first metal gasket between the feedthrough conductor and the first metal gasket to form a seal therebetween. The methods may further include compressing the second metal gasket between the body and the first insulator to form a seal therebetween. Induction furnace systems may include one or more such feed assemblies.

Disclosed herein is an implantable pulse generator for administering electrotherapy via an implantable lead.
