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.

Abstract: An ET guide is provided which is preferably made of polytetrafluoroethylene (PTFE), also known as Teflon®. The distal end is of a reduced profile so that the guide can be left in place, with the ET removed in the operating room just prior to a tracheostomy. If for any reason problems are encountered in the tracheostomy procedure, the guide of the present invention, having been left in after the removal of the ET, can facilitate a reinsertion of the ET to avoid danger to the patient from a decrease in oxygen saturation. At the same time, the reduced distal profile allows the guide to remain in place during the tracheostomy procedure without obstructing the area of the incision for the tracheostomy. The guide can remain in place until the tracheostomy is successfully concluded, at which point it can be optionally removed.
