An implantable endocardial, multi-lumen lead wherein the distal end of the lead body is cored to provide a stopped bore co-axial with the axis of the lead body. A distal electrode is inserted into the stopped bore without an additional tubular segment and glue joint. A first lumen in the lead body has an axis which is off set from the axis of the lead body itself. A low voltage conductor passes through the first lumen. A second lumen is also offset from the axis of the lead body. The lumens may have a circular or other cross section. A plurality of non-coaxial lumens may be provided.

Endocardial defibrillation lead with multi-lumen body and axially mounted distal electrode

An implantable endocardial defibrillation lead having an elongated lead body with multiple lumens therein. Windows, cut through the lead body, provide access to selected ones of the lumens at selected locations along the lead body. In addition, a method and an apparatus for forming windows in a multilumen lead body are disclosed. A ferromagnetic stylet is inserted into a selected lumen. The lead body is oriented in a jig by application of an electromagnetic field. A grinder or punch cuts a window into the selected lumen.
