Abstract: According to aspects disclosed herein, an infusion lead assembly may include a housing including a needle receptacle, a housing lumen, a pin receptacle, and a housing conductive trace; a connector including an connector needle, an internal lumen, a metal pin, and a connector conductive trace, and an infusion lead body including an infusion lumen, an exit port, an internal wire, and a distal electrode. The infusion lead assembly may form an electrical path to transmit electrical signals across the connector conductive trace, the metal pin, the housing conductive trace, the internal wire, and the distal electrode. The infusion lead assembly may form a fluid path to transmit fluid across the internal lumen, the connector needle, the infusion lumen, and the exit port.

Abstract: A method and apparatus are disclosed for anesthetizing a region of a patient's body. The method includes identifying a target nerve which, upon activation, anesthetizes a region of a patient's body including a surgical site. The target nerve is located and an active site of a nerve blocking apparatus is placed in proximity to the nerve. The nerve blocking apparatus is activated to block neural propagation along the nerve. The activation of the nerve blocking apparatus is maintained during a surgical procedure at the surgical site.
