Abstract: A surgical retractor assembly is provided having a frame that releasably couples two retractor blades. The retractor blades are coupled to the frame via a pair of mobile carriages that engage a track on the frame. A third retractor blade is configured to be independent of the frame with the first two retractor blades. The independent blade may be fixably positionable in the patient by a direct coupling to a rigid table mount. The retractor assembly may be utilized for creating anterior access to spinal target site while the patient is oriented in the lateral decubitus position.

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: A foldable stringed instrument, for example in the form of a travel guitar that folds mid-neck to assume a reduced profile is described. The mid-neck folding is accomplished in a symmetrical manner about a three-part hinge located in the neck to configure the travel guitar into a reduced profile. The bridge assembly can be translated longitudinally relative to the head of the guitar to allow sufficient de-tensioning of the guitar strings to enable an upper portion of the neck to be folded away from a lower portion of the neck and/or body to assume a reduced profile. To deploy the travel guitar for playing, the upper portion of the neck is unfolded into alignment with the lower portion of the neck and/or body, and the bridge assembly translated longitudinally relative to the head and locked in position to allow the guitar to be tuned for playing.

Abstract: This application describes surgical instruments and implants for building a posterior fixation construct across one or more segments of the spinal column. More specifically, the application describes instruments and methods for building a posterior fixation construct across one or more segments of the spinal column in a minimally invasive fashion.

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.
