Abstract

A medical device for transmitting an electric pulse to vascular tissue proximate an implantable catheter to prevent vascular occlusion. The medical device includes an elongate body defining a proximal and distal end. The elongate body further defines an injection lumen and a wire lumen, the injection lumen being in fluid communication with a fluid source. A wire is at least partially disposed within the elongate body, and has a proximal end and a distal end. The distal end of the wire is at least partially disposed within the wire lumen, and the proximal end of the wire is connected a pulse generator, wherein the pulse generator transmits an electric pulse along the wire toward the distal end of the elongate body.
