Implantable medical devices including elongated conductor bodies that facilitate device and lead configuration variants

摘要

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.

主权项

1. An implantable medical device, comprising:
a housing; circuitry within the housing; a feedthrough electrically connected to the circuitry and providing at least one feedthrough conductor externally of the housing; a harness mounted to the housing, the harness comprising:
an elongated body having a proximal end and a distal end;at least one conductor in the body, the at least one conductor being electrically coupled to the at least one feedthrough conductor in proximity to the proximal end of the body;a connector attached to the distal end of the body, the connector defining at least one lead passageway and comprising at least one electrical contact that is electrically coupled to the at least one feedthrough conductor, the at least one electrical contact surrounding the lead passageway and having a thickness in an axial direction of 0.040 inches or less.
