An implantable pulse generator (IPG) is fabricated by utilizing a lead body with a plurality of conductors enclosed in insulative material along a first length of the conductors, and a second length of the conductors being exposed. A tubular structure is placed over the lead body with the plurality of conductors extending through it. A feedthrough assembly includes a plurality of feedthrough pins surrounded by insular material with a ferrule extending about an outer surface of the feedthrough assembly. The plurality of conductors are attached to the plurality of feedthrough pins and the ferrule of the feedthrough assembly is welded to the tubular structure to form an intermediate assembly. The intermediate assembly is then welded to one or more housing components of the IPG providing a hermetically seal. A connector portion on a distal end of the lead body is provided to electrically connect to terminals of a stimulation lead.

Method of fabricating implantable pulse generator using wire connections to feedthrough structures and implantable pulse generators

A method of fabricating an implantable pulse generator for generating electrical pulses for application to tissue of a patient, the method comprises: providing one or more housing components adapted to house at least pulse generating and switching circuitry of the implantable pulse generator; providing a feedthrough assembly adapted to be coupled with the one or more housing components, the feedthrough assembly comprising an array of feedthrough pins for providing respective electrical connections from a hermetically sealed enclosure formed within the one or more housing components to a location exterior to the enclosure; providing a plurality of welding components with each welding component comprising a first portion adapted to engage a respective feedthrough pin and a second portion for engaging a conductor wire; performing one or more weld operations for each welding component to connect each welding component with a respective feedthrough pin and a respective conductor wire.

In one embodiment, a method of fabricating an implantable pulse generator, comprises: providing a lead body including a plurality of conductors; providing a feedthrough component comprising feedthrough pins; electrically coupling pulse generating circuitry through switching circuitry with the feedthrough pins; hermetically enclosing the pulse generating circuitry and switching circuitry within a housing; providing a ferrule tube connector about each feedthrough pin wherein (i) each ferrule tube connector comprises an inner diameter that is sized to make contact about a circumference of respective feedthrough pin, and (ii) each ferrule tube connector comprises at least one slot in an upper portion of the respective ferrule tube connector; placing a respective conductor of the plurality of conductors in the slot of each of the ferrule tube connectors; and performing welding operations to connect the plurality of conductors of the lead body with the ferrule tube connectors.

In one embodiment, a method of fabricating an implantable pulse generator, comprises: providing a lead body including a plurality of conductors; providing a feedthrough component comprising a plurality of feedthrough pins; hermetically enclosing pulse generating circuitry and switching circuitry within a housing, the feedthrough component being welded to the housing; laser machining each of the plurality of feedthrough pins to comprise a slot along a surface of the respective feedthrough pin; placing a respective conductor from the lead body in the respective slot of each of the plurality of feedthrough pins; and performing welding operations to connect the plurality of conductors of the lead body with the plurality of feedthrough pins of the feedthrough component.
