Abstract: An implantable medical device having a case with therapeutic componentry contained with the case. A module has a rail around at least a portion of a perimeter of the module and is adapted to be mechanically secured to the case. The case has a rigid fastening channel adapted to receive the rail of the module. The rigid fastening channel has an opening allowing the rail of the module to drop into the rigid fastening channel through the opening and then slide along the rigid fastening channel to be mechanically secured to the case.

Abstract: A laminate having a plurality of layers of magnetic material sandwiched together having a first side and a second side and a method of making the laminate. The plurality of layers of magnetic material having a plurality of radial grooves. A first insulative layer applied over the first side of the plurality of layers of magnetic material. A lead wire applied to over first insulative layer at a predetermined location on the first side of the plurality of layers of magnetic material. A second insulative layer applied to the first side of the plurality of layers of magnetic material over the lead wire. A third insulative layer applied to the second side of the plurality of layers of magnetic material. Thus, the laminate is ready to receive a coil.

Abstract: Implantable medical devices (IMDs) comprising a monitor or implantable pulse generator (IPG) having an IPG header to which lead connector assemblies of electrical medical leads are coupled, particularly, an improved in-line IPG header providing enhanced durability, ease of manufacture, and ease of use. A stack of alternating, substantially tubular electrically insulating fluid seals and header connector elements is assembled in axial alignment to form a common, elongated axial stack bore sized in diameter and length to receive the lead connector assembly. Each adjacent electrical connector element and fluid seal are interlocked with one another during assembly of the stack to maintain the axial alignment and the length and diameter dimensions. Fluid seals are located at each end of the stack, and the stack can be inserted as a unit into a cavity of the IPG header.

Abstract: An apparatus and method of electrically connecting components of an implantable medical device are disclosed. One embodiment is an apparatus having at least one electrical connector comprising a tab section and a housing at least partially enclosing the electrical connectors, wherein the housing is molded into sealing engagement with the electrical connectors and the tab section is capable of removal from the electrical connector after the housing is molded.
