Abstract
A smooth muscle stimulation device is intended for use with any one of a variety of electrosurgical units (ESU's) of the type used in tissue resection and other procedures that risk damage to non-target tissues. The smooth muscle stimulation devices typically include an enclosure with stimulation circuitry configured to generate a stimulatory electrical signal which when delivered to a target anatomy induces an observable response in the target anatomy during a medical procedure. An input connector on the enclosure detachably couples to a power output of the ESU, and an output connector on the enclosure detachably couples to an electrosurgical tool. Switching circuitry within the enclosure selectively connects either the power output of the ESU or the stimulatory electrical signal of the stimulation circuitry to the output connector in response to user input.
