Implantable medical device having feedthru assembly with header side bunched conductor array and can side linear conductor array

An implantable pulse generator comprising:

• a header including lead connector blocks;
• a can coupled to the header and including a wall and an electronic substrate housed within the wall, the electronic substrate including an electrical connection region;
• and
• a feedthru assembly including a feedthru mounted in the wall and a feedthru board coupled to the feedthru and housed within the wall, the feedthru having a feedthru housing and an electrically insulative core disposed within the feedthru housing;
• wherein a grouped array of feedthru wires extends from the connector blocks, through the and into the feedthru board;
• wherein a linear array of conductor wires extends from a side of the board opposite the feedthru;
• wherein each feedthru wire is in electrical communication with a respective conductor wire;
• and
• wherein each conductor wire is received in the electrical connection region.

A method of manufacturing an implantable pulse generator, the method comprising:

• providing a feedthru assembly having a feedthru with a feedthru housing, an electrically insulative core disposed within the feedthru housing, and a bunched array of feedthru wires extending from a header side of the feedthru and a linear array of conductor wires extending from a can side of a feedthru board of the assembly, the feedthru board being adjacent a can side of the feedthru;
• coupling the bunched array of feedthru wires to connector blocks in a header of the pulse generator;
• and
• extending the linear array of conductor wires into an electrical connection region of an electronic substrate housed within a can of the pulse generator.
