Patent ID: 6968237

Claim:
An implantable stimulation lead comprising: at least one proximal connector; at least one tissue stimulation electrode; at least one conductor coupling the at least one proximal connector with the at least one stimulation electrode; a lead body of insulating material enclosing the at least one conductor, the lead body having a distal portion carrying the at least one tissue stimulation electrode, the lead body further having a proximal portion extending from the at least one proximal connector to a joint coupling the distal and proximal portions of the lead body, the joint comprising telescoped sections of the distal and proximal portions of the lead body, the telescoped sections of the distal and proximal portions of the lead body comprising a cored out section in one of the portions of the lead body and a reduced diameter section on the other of the portions of the lead body, the at least one conductor comprising a series combination of a first conductor within the proximal portion of the lead body and a second conductor within the distal portion of the lead body, a distal end of the first conductor being electrically connected within the joint to a proximal end of the second conductor, the cored out section of the distal portion of the lead body having a length greater than that of the reduced diameter section of the proximal portion of the lead body so as to define a space between distal ends of the reduced diameter and cored out sections, the space being filled with medical adhesive thereby isolating the proximal end of the second conductor from the proximal portion of the lead body.
