Abstract: A reinforced medical electrical lead for neurological applications has a reinforced construction for resisting the detachment of electrodes and lead connection terminals, thereby improving the robustness of the lead and extending the life of the lead by reducing the likelihood that a further surgical procedure will be required to remove the lead for repair or replacement thereof. The present reinforced lead construction maintains the integrity of the electrical connection between the conductor and the respective electrode and lead connection terminal by incorporating several reinforcing features in the lead construction in contrast to conventional lead constructions where it is possible to pull the electrodes and lead connection terminals away from their contact points with relatively little force.

Abstract: A medical electrical lead system for neurological applications has a distal portion having a plurality of independently positionable seed electrodes, each of which may be connected via an interface to an implantable medical device. The interface allows the seed electrodes to be positioned, then excess wire trimmed, facilitating simplified connection of multiple independent electrodes to a single device. Seed electrodes according to the invention are small, have relatively low mass, and are minimally destructive of surrounding tissue.
