Systems and techniques for nerve monitoring are described herein. The system can include a remote transmitter configured to send a stimulation signal to a nerve, and an electrosurgical device including an end effector configured to perform a surgical function in response to receiving a therapeutic signal from an electrosurgical generator. The system can also include a receiver configured to detect the stimulation signal, and in response to detecting the stimulation signal, determine a location of the nerve, and an in-vivo transmitter configured to emit a location signal in response to the determined location of the nerve.

The invention relates to an implantable sensor for detecting an electrical excitation of muscle cells, in particular cardiac muscle cells, wherein it is provided that the sensor comprises a dielectric component and a contact point for contacting muscle cells, which is connected to the dielectric component, so that an electric field in the dielectric component, and correspondingly a capacitance of the dielectric component, change with an electrical excitation of the muscle cells. The invention furthermore relates to a system comprising a sensor and an implant.

A method of monitoring a patient for phrenic nerve collateral damage during a cardiac ablation procedure. The method includes measuring at least one from the group consisting of compound motor action potential (CMAP) and accelerometer signals in response to stimulating of the phrenic nerve. Real-time data is displayed on a display, the real-time data including the at least one from the group consisting of the measured CMAP and accelerometer signals. Long-term trend data is simultaneously displayed on the display, the long-term trend data being associated with the measured at least one from the group consisting of CMAP and accelerometer signals.

A surgical access system including a tissue distraction assembly 40 and a tissue retraction assembly 10, both of which may be equipped with one or more electrodes 23 for use in detecting the existence of (and optionally the distance and/or direction to) neural structures before, during, and after the establishment of an operative corridor 15 to a surgical target site. The tissue retraction assembly 10 has a plurality of blades 12, 16, 18 which may be introduced while in a closed configuration, after which point they may be opened to create an operation corridor 15 to the surgical target site, including pivoting at least one blade 12, 16, 18 to expand the operative corridor 15 adjacent to the operative site.

Systems and methods for digital reflex quantization and signature analysis. Movement of a stimulating device invoking a reflex response in an organism is captured as stimuli data. Electromyographic (EMG) of the reflex response is captured as EMG data. Movement resulting from the reflex response of a limb/appendage of the organism is captured as motion data. One or more of the stimuli data, the EMG data, and the motion data are analyzed to determine one or both of a motion signature and an EMG signature defining quantitative evaluation of the reflex response.
