Abstract:
1. An electrostimulation lead, comprising: a lead body, including a proximal portion and a distal portion; a plurality of conductors disposed within the lead body extending substantially from the proximal portion to the distal portion; a plurality of cylindrical terminals at the proximal portion of the lead body, the plurality of terminals being surrounding by molded polymer material, wherein each terminal of the plurality of terminals comprises a plurality of notches disposed circumferentially along each outer peripheral edge of the respective terminal; and a plurality of cylindrical electrodes at the distal portion of the lead body, the plurality of electrodes being surrounding by molded polymer material, the plurality of conductors electrically coupling the plurality of electrodes with the plurality of terminals, wherein each electrode of the plurality of electrodes comprises a plurality of notches disposed circumferentially along each outer peripheral edge of the respective electrode, wherein each electrode of the plurality of electrodes comprises four notches on each peripheral edge operable to substantially eliminate gaseous material from being trapped about each electrode during a molding process of the electrostimulation lead.
