Patent number: 9622735Abstract: A surgical access system for accessing a surgical target site within a spine includes a retractor and an elongated element. The refractor has a closed configuration defining a lumen with an internal circumference, and an open configuration in which the internal circumference, at least at the distal end of the retractor, is enlarged relative to said closed configuration. The open configuration creates and maintains an operative corridor to said target site. The elongated element is releasably coupled to an interior wall of the retractor and has an extension extending distal of the distal end of the retractor into the surgical target site. When coupled to the retractor, the elongated element covers a body structure at the target site without blocking access to the operative corridor.Type: GrantFiled: October 20, 2014Date of Patent: April 18, 2017Assignee: Zimmer Spine, Inc.Inventors: James J.

Publication number: 20060293678Abstract: A device suitable for providing access through an incision in the skin of a patient to a spinal location within the patient is provided. The device comprises an elongate body having a proximal end and a distal end. The distal end of the elongate body can comprise an oblong perimeter. The proximal end can be positioned outside of the patient and the distal end can be positioned inside the patient adjacent the spinal location. The elongate body can be enlarged such that a transverse dimension at a first location is greater than a transverse dimension at a second location, where the first location is distal to the second location. The elongate body provides an access path through the incision to the spinal location such that one or more surgical instruments can be advanced simultaneously along the access path between the proximal end and the spinal location.Type: ApplicationFiled: May 3, 2006Publication date: December 28, 2006Inventors: Thomas Davison, Timothy Taylor, Adam Sher
