Patent ID: 7953496

Claim:
An implantable lead with an isolated contact connection, comprising: a lead body having a proximal and distal end; at least one conductor within the lead body traversing from the proximal end to the distal end; at least one contact carried on the proximal end and electrically connected to the conductor; at least one contact carried on the distal end and electrically connected to the conductor and having an inside surface and an outside surface and having a contact slot extending from the inside surface to the outside surface, the contact slot having a first and a second edge parallel to the conductor and a proximal or distal end which is open with no edge; and, at least one conductor coupling being partially placed over the conductor and being attached to the conductor; the conductor coupling being placed in the contact slot on the at least one contact, and the conductor coupling having a weld to connect the conductor coupling to the distal end contact, wherein the conductor coupling creates an isolation space between the conductor and the contact to prevent directly welding the conductor to the contact.
