Implantable medical devices including elongated conductor bodies that facilitate device and lead configuration variants
First Claim
1. A method of constructing an implantable medical device, comprising:
- providing a housing;
providing circuitry within the housing;
providing a feedthrough electrically connected to the circuitry and providing a plurality of feedthrough conductors externally of the housing;
providing an elongated body having a proximal end and a distal end;
providing a plurality of conductors in the body, the plurality of conductors being electrically coupled to the feedthrough conductors in proximity to the proximal end of the body;
attaching a connector to the distal end of the body, the connector comprising;
a plurality of adjacent contact modules, each contact module having at least one lead passageway;
a plurality of contact isolators, with contact isolators of the plurality being disposed within each of the at least one lead passageways of the corresponding contact modules of the plurality; and
a plurality of electrical contacts positioned within the lead passageway of each contact module, with at least one electrical contact of the plurality being located axially between contact isolators, each of the plurality of contacts being in electrical communication with at least one of the conductors.

Abstract
Implantable medical devices include elongated conductor bodies and related features including an attachment to the medical device at one end and a connector that receives a medical lead at the other end. The connector may have various features such as a modular design whereby the connector is constructed from a series of stacked contact modules. Other features of the connector include electrical contacts that are relatively thin conductors or the order of 0.040 inches or less and that may include radial protrusions to establish contact with the electrical connectors of the lead. Furthermore, electrical contacts may be mounted within the connector in a floating manner so that radial movement of the electrical contact may occur during lead insertion. Additional features include a feedthrough where conductors exposed beyond a housing of the implantable medical device make direct electrical connection to conductors present within the elongated body.
