Embodiment Construction

[0020]A variety of embodiments and examples described herein illustrate various configurations that may be employed to achieve desired improvements. The particular embodiments and examples are only illustrative and not intended in any way to restrict the general nature of the inventions presented and the various aspects and features of and relating to these inventions.

[0021]FIGS. 1 through 13 illustrate various perspective views of one embodiment of a retractor 2000 that is particularly useful in procedures using a lateral access approach to a targeted portion of the spine. As shown, the overall shape of the retractor 2000 can be generally rectangular (e.g., square) or diamond. However, in other embodiments, the shape of the retractor can vary, as desired or required. For instance, in some embodiments, the retractor comprises a generally circular, oval, other polygonal (e.g., triangular, pentagonal, hexagonal, octagonal, etc.), irregular and / or any other shape. The retractor can be ...

Abstract

According to some embodiments, a retractor device for selectively moving (e.g., retracting) anatomical tissue of a subject during a minimally invasive procedure (e.g., accessing the lumbar or other portion of a spine during a spinal fusion procedure) comprises a main body comprising at least three sides (e.g., three, four, five sides, more than five sides, etc.). In some embodiments, the main body defines or otherwise forms a central opening, which comprises a center-point positioned along a centerline of the central opening. In some embodiments, the retractor device further comprises a plurality of movable members secured to the main body.

Description

PRIORITY DATA[0001]This application is a continuation application of U.S. patent application Ser. No. 13 / 666,829, filed Nov. 1, 2012, which claims the priority benefit under 35 U.S.C. §119(e) of U.S. Provisional Patent Application No. 61 / 554,958, filed Nov. 2, 2011, the entireties of both of which are hereby incorporated by reference herein.BACKGROUND[0002]Field[0003]This application generally relates to spinal treatment, and more specifically, to devices and instrumentation for accessing certain portions of the spine minimally invasively, and related systems and methods.[0004]Description of the Related Art[0005]Intervertebral discs can degenerate or otherwise become damaged over time. In some instances, an intervertebral implant can be positioned within a space previously occupied by a disc. Such implants can help maintain a desired spacing between adjacent vertebrae and / or promote fusion between adjacent vertebrae. In order to minimally invasively access a target portion of the sp...
