AI Technical Summary

Benefits of technology

The present disclosure relates to lead connectors with glass insulators, specifically hermetic lead connectors that have contact portions separated by electrically insulating glass material. The electrically insulating glass material can form a hermetic bond with the electrically conducting contact portions of the hermetic lead connectors. This disclosure provides a solution for creating a reliable and secure connection between electrically conducting contact rings in a lead connector, which can be used in various medical devices.

Problems solved by technology

While this arrangement has proven to be highly reliable, it involves a variety of expensive manufacturing processes and parts that necessarily increase the cost of the resulting product and increases the number of interconnects.

Abstract

A medical device lead connector includes two or more electrically conducting contact rings spaced apart by electrically insulating glass material. The electrically insulating glass material fixes the two or more electrically conducting contact rings in axial alignment.

Description

RELATED APPLICATION[0001]This patent application claims priority to U.S. Provisional Patent Application Ser. No. 61 / 299,167, filed Jan. 28, 2010, the entire disclosure of which is expressly incorporated herein by reference.BACKGROUND[0002]Implantable active medical devices, such as cardiac rhythm management devices (pacemakers and defibrillators) and a variety of implantable muscle / nerve stimulators, for example, generally include a battery and battery-powered electronic pulse generator contained within a hermetically sealed housing or case and attached to a lead connector housing or block. The lead connector block is often affixed to the hermetically sealed housing with brackets, and / or a medical grade adhesive.[0003]The electronics within the hermetically sealed housing are conductively coupled to the lead connector block with an electrical feedthrough assembly. Electrical feedthroughs serve the purpose of providing a conductive path extending between the interior of a hermeticall...
