Abstract
A multi-conductor fluted channel construction catheter lead is comprised of an elongated flexible tubular inner body member having a peripheral surface on which a plurality of longitudinally-oriented fluted channels are defined. A plurality of elongated conductors are provided with at least one conductor being disposed within one of the fluted channels and operably connected at a distal portion to an electrode and at a proximal portion to a connector. An outer insulative sheath member surrounds the inner body member and the conductors. A method of constructing a fluted channel catheter lead is also disclosed.

A multi-conductor catheter lead comprising:
- an elongated flexible tubular inner body member having a peripheral surface around which are defined a plurality of longitudinally-oriented fluted channels;
- a plurality of elongated conductors, at least one electrode and at least one connector, at least one of the conductors being disposed within at least one of the plurality of fluted channels and each conductor operably connected at a distal portion of the conductor to an electrode and at a proximal portion of the conductor to a connector;
- a stiffening material filling at least a portion of at least one of the plurality of longitudinally-oriented fluted channels that is open and without a conductor such that the stiffening material generally shapes the catheter lead along a length of the catheter lead corresponding to the portion which is filled;
- and
- an outer insulative member surrounding the inner body member and the conductors.
