Abstract
A catheter switch comprising a first electrical connector for connection to a first medical device, a second electrical connector for connection to a second medical device, and a third electrical connector for connection to a signal source. The catheter switch further includes an electrical switch coupled to the first, second, and third electrical connectors. The electrical switch is configured to include at least two selectable positions, a first position in which the first electrical connector is electrically coupled to the third electrical connector and a second position in which the second electrical connector is electrically coupled to the third electrical connector. A catheter switch assembly system is also provided. The catheter switch assembly system is for selectively coupling a nerve stimulator to a needle assembly or to a catheter assembly to deliver electrical pulses thereto.
