Abstract:
1. An implantable pulse generator for electrically stimulating a patient, comprising: a metallic housing enclosing pulse generating circuitry; and a header mechanically coupled to the metallic housing, the header adapted to seal terminals of a plurality of stimulation leads within the header and to provide electrical connections for the terminals, the header comprising an outer shield component, a plurality of electrical connectors electrically coupled to the pulse generating circuitry through feedthrough wires, and an inner compliant component; wherein (i) the inner compliant component is an integral, single piece of compliant material, (ii) the inner compliant component comprises a plurality of walls defining a plurality of recesses, (iii) the plurality of electrical connectors are held in the plurality of recesses by an elastomeric force applied by the plurality of walls, (iv) the plurality of walls comprise a plurality of apertures defining two respective parallel channels through the inner compliant component, and (v) the outer shield component is fit over at least a portion of the inner compliant component containing the plurality of electrical connectors to protect the inner compliant component from punctures from surgical implant tools; wherein (i) the header further comprises an antenna component that comprises an exterior shell enclosing an antenna for far field communications, (ii) the antenna comprises a plurality of discrete turns disposed in a substantially planar orientation relative to a top portion of the exterior shell, (iii) the exterior shell comprises a plurality of slots having reduced thickness in the exterior shell, and (iv) the discrete turns of antenna are disposed immediately beneath the plurality of slots of the exterior shell.
