A surgical access system including a tissue distraction assemblyand a tissue retraction assembly, both of which may be equipped with one or more. electrodesfor 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 corridorto a surgical target site. The tissue retraction assemblyhas a plurality of bladeswhich may be introduced while in a closed configuration, after which point they may be opened to create an operation corridorto the surgical target site, including pivoting at least one bladeto expand the operative corridoradjacent to the operative site.

Surgical access system and related methods

A surgical access system including a tissue distraction assembly and a tissue retraction assembly, both of which may be equipped with one or more electrodes 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 to a surgical target site.

A pedicle access system including a cannula, a stylet, and a removable T-handle. The pedicle access system may be used to percutaneously approach the pedicle, initiate pilot hole formation, and conduct a stimulation signal to the target site for the purposes of performing a pedicle integrity assessment during the pilot hole formation. To do this, the cannula and stylet are locked in combination and inserted through an operating corridor to the pedicle target site, using the T-handle to facilitate easy movement and positioning of the cannula/stylet combination. A stimulation signal may be applied during pilot hole formation to conduct the pedicle integrity assessment. In a significant aspect, the T-handle may be detached from the cannula/stylet combination to facilitate the use of various surgical tools as necessary.

Insulated pedicle access system and related methods

A surgical access system including a tissue distraction assembly and a tissue refraction assembly, both of which may be equipped with one or more electrodes 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 to a surgical target site.

A system for accessing a surgical target site and related methods, involving an initial distraction system for creating an initial distraction corridor, and an assembly capable of distracting from the initial distraction corridor to a secondary distraction corridor and thereafter sequentially receiving a plurality of retractor blades for retracting from the secondary distraction corridor to thereby create an operative corridor to the surgical target site, both of which may be equipped with one or more electrodes 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 to a surgical target site.

A surgical access system including a tissue distraction assembly and a tissue retraction assembly, both of which may be equipped with one or more electrodes 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 to a surgical target site. Some embodiments of the surgical access system may be particularly suited for establishing an operative corridor to a surgical target site in the spine. Such an operative corridor may be established through the retroperitoneal space and the psoas muscle during a direct lateral, retroperitoneal approach to the spine.

The present invention involves systems and related methods for performing surgical procedures and assessments, including the use of neurophysiology-based monitoring to: (a) determine nerve proximity and nerve direction to surgical instruments employed in accessing a surgical target site; (b) assess the pathology (health or status) of a nerve or nerve root before, during, or after a surgical procedure; and/or (c) assess pedicle integrity before, during or after pedicle screw placement, all in an automated, easy to use, and easy to interpret fashion so as to provide a surgeon-driven system.
