Abstract:
1. An intraoperative neural monitoring system comprising a power source; a stimulator powered by said power source to deliver electrical stimulation for application to anatomical tissue, said stimulator delivering said electrical stimulation alternatively as a complete cycle of monophasic electrical stimulation having a selected number of positive or negative pulses, or a complete cycle of biphasic electrical stimulation having a first group of a selected number of positive or negative pulses automatically followed by a second group of a selected number of pulses of reverse polarity to said pulses of said first group; an activator for said stimulator actuatable by a user of said intraoperative neural monitoring system to start delivery of said electrical stimulation; and a mode selector for said stimulator having a monophasic mode setting selectable by a user of said intraoperative neural monitoring system, prior to actuation of said activator, to set said stimulator to deliver said complete cycle of monophasic electrical stimulation in response to actuation of said activator to start delivery of said electrical stimulation, and having a biphasic mode setting alternatively selectable by a user of said intraoperative neural monitoring system, prior to actuation of said activator, to set said stimulator to alternatively deliver said complete cycle of biphasic electrical stimulation in response to actuation of said activator to start delivery of said electrical stimulation.
