Patent ID: 7546163

Claim:
A medical electrical lead, comprising: a lead body having a lead body lumen, the lead body having a distal end and a proximal end; an electrode head assembly including a tip electrode and a defibrillation coil in proximity to the tip electrode, the electrode head assembly having an electrode head assembly lumen communicating with the lead body lumen; a joint coupling the electrode head assembly to the distal end of the lead body; a connector assembly at the proximal end of the lead body; a conductor extending within the lead body lumen and the electrode head assembly lumen between the tip electrode and the proximal end of the lead body; a continuous, unitary insulation tube extending from the electrode head assembly lumen, through the lead body lumen to the connector assembly for electrically isolating the conductor from the defibrillation coil, the continuous, unitary insulation tube extending across the joint coupling the electrode head assembly and the lead body.
