Abstract: A surgical access system comprising a tissue dilation 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.

Abstract: This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column during a medialized posterior lumbar interbody fusion (PLIF) procedure.

Abstract: This application describes a surgical retractor and related methods for providing access to a surgical target site for the purpose performing minimally invasive spinal fusion across one or more segments of the spinal column.

Abstract: A surgical retractor assembly is provided that can assume both open and closed positions, and is easily convertible from one position to the other. The retractor assembly involves an arcuate frame member that can be engaged to an arcuate connector, which together form a generally circular or elliptical retractor frame assembly. The frame member has a groove for the insertion of one or more mobile carriages that hold retractor blade posts and allow the posts to move in multiple directions. The carriages may be locked to prevent movement in one or more directions, as well.

Abstract: A travel guitar having a neck and/or body that may assume a reduced profile configured to house or otherwise receive or coupled to a tablet computer (e.g. iPad by Apple, Inc.) and/or a smart phone (e.g. iPhone by Apple, Inc.) having one or more applications (apps) for driving the operation, functionality and/or effects associated with the travel guitar, and a string assembly capable of retracting or otherwise housing the strings to enable or facilitate configuring the travel guitar into a reduced profile.

Abstract: A surgical access system comprising a tissue dilation 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 and one or more pressure sensors for determining and monitoring pressure on neural structures near the tissue dilation assembly or the tissue retraction assembly.

Abstract: A surgical access system comprising a tissue retraction assembly equipped with two or more electrodes for use in monitoring the status of nearby neural structures, including the localized depth of neural structures relative to one or more components of the tissue retraction assembly. Additional neurological testing may be performed to monitor the health and status of the neural structures during the portions of the surgical procedure in which the tissue retraction assembly is used to maintain the operative corridor.
