Abstract
An implantable multi-lumen, multi-conductor lead for use with an implantable medical device. The completed lead is an assembly of a polymeric lead body with several coiled conductors inserted into the lead body. The lead body includes several lumens having a generally rounded-corner triangular or "pie-shaped" cross-section. The conductors do not fill the lumens, and only contact the inner walls of the lumens at discrete points, rather than for extended sections of or all of the circumference of the conductors. Preferably the coils are sized so that they fit loosely within the lumens.
