Abstract

The present invention generally relates to a dilator with a curved tip. The curved tip is machined through a specific range of diameters so that a physician can establish the diameter of the opening with the dilator inserted. The angle of the dilator also allows the physician to access the interspinous ligament through a minimally invasive opening in the patients back, minimizing the trauma caused to surrounding body tissue.
