An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (˜16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (˜5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, 'ultra-MIS' techniques.

Multi-shield spinal access system

The present invention relates to a system and related methods for performing neurophysiologic assessments during surgical procedures. A method includes the steps of delivering a first transcutaneous, trans-abdominal stimulation signal to a spinal nerve root superior to a surgical target site; and determining a first neuromuscular response data set, based on transmission of said first transcutaneous, trans-abdominal stimulation signal, of a muscle located inferior to said surgical target site.

Systems and methods for performing neurophysiologic monitoring during spine surgery

An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (&#x2dc;16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (&#x2dc;5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, 'ultra-MIS' techniques.

A neuromonitoring system utilizes transcutaneous, trans-abdominal nerve root stimulation to monitor the health and status of the motor neural pathways of the lower extremities during the portions of a surgical procedure in which a tissue retraction assembly is used to maintain an operative corridor. A method of monitoring the status of nerve during a spinal surgical procedure delivers a transcutaneous, trans-abdominal stimulation signal to the spine. A determination is made of a stimulation threshold required to elicit a neuromuscular response from the stimulation signal.
