Patent number: 7682370Abstract: A surgical tool for use in expanding a tubular structure having an inner surface defining a passage through the tubular structure for receiving surgical instruments includes a first leg having a first end engageable with the inner surface of the tubular structure. A second leg has a second end engageable with the inner surface of the tubular structure. The first and second ends are movable away from each other to apply a radially outwardly directed force to the inner surface of the tubular structure and cause expansion of the tubular structure to increase a cross-sectional area of the passage along a portion of the passage.Type: GrantFiled: September 19, 2003Date of Patent: March 23, 2010Assignee: Zimmer Spine, Inc.Inventors: James J.

Patent number: 7674273Abstract: A method of performing a surgical procedure on a body includes providing a cannula having a tubular structure with first and second tubular portions defining first and second passages for receiving surgical instruments. The second tubular portion is inserted inside the body and the first tubular portion is inserted so that the first tubular portion extends from an exterior of the body to inside the body. The second tubular portion expands to increase the cross-sectional area of the second passage in the second tubular portion while the second tubular portion is inside the body. The cross-sectional area of the first passage in the first tubular portion is maintained. The first tubular portion has a first thickness and the second tubular portion has a second thickness different than the first thickness.Type: GrantFiled: October 5, 2004Date of Patent: March 9, 2010Assignee: Zimmer Spine, Inc.Inventors: Thomas W.

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
