Abstract
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.
Claims6
A method for constructing a cardiac stimulation lead comprising the steps of:
- forming an elongated lead body having a proximal end, a distal end, and an axis and having a lumen in said lead body, said lumen having an axis off set from said axis of said lead body;
- coring a stopped bore at said distal end of said lead body, said stopped bore being formed in said lead body and having an axis which coincides with said axis of said lead body;
- inserting an electrical conductor in said lumen;
- electrically connecting said conductor to an electrical connector at said proximal end;
- electrically connecting a first electrode at said distal end to said conductor;
- and
- inserting a shank on said electrode into stopped bore at said distal end of said lead body.
