REINFORCED SENSING AND STIMULATION LEADS AND USE IN DETECTION SYSTEMS

摘要

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.

主权项

1. A medical electrical lead adapted to be at least partially implanted in a human patient, the lead comprising:
a proximal portion having a lead connection area having at least one lead connection terminal; a distal portion having at least one electrode; at least one conductor providing communication between the at least one electrode and the lead connection area; a first stiffening sheath disposed at the proximal portion; a bushing disposed at a proximal end of the proximal portion, the busing having a bore formed therein; and a body interconnecting the proximal portion and the distal portion, wherein a proximal end of the first stiffening sheath is coupled to one end of the bushing, and the first stiffening sheath defines an inner lumen which is axially aligned with the bore.
