Abstract:
A dilator retractor and the dilators that are used for minimally invasive spinal surgery or other surgery are configured to accommodate the anatomical structure of the patient as by configuring the cross sectional area in an elliptical shape, or by forming a funnel configuration with the wider end at the proximate end. In some embodiments the distal end is contoured to also accommodate the anatomical structure of the patient so that a cylindrically shaped, funnel shaped, ovoid shaped dilator retractor can be sloped or tunneled to accommodate the bone structure of the patient or provide access for implants. The dilator retractor is made with different lengths to accommodate the depth of the cavity formed by the dilators.

Claim (Index 21):
A dilator kit, comprising:\n a non-cannulated dilator having an elongated cylindrical solid body with a tool engaging portion at a proximal end thereof and a pointed tip portion at a distal end thereof; a plurality of cannulated dilators, at least one of the cannulated dilators having an ovoid cross-section; the plurality of cannulated dilators includes a first cannulated dilator having a circular interior cross-section and an ovoid exterior cross-section and a second cannulated dilator having an ovoid interior cross-section and an ovoid exterior cross-section; and at least one of the plurality of cannulated dilators having a distal facing surface disposed in a plane that is substantially perpendicular to a longitudinal axis of the at least one of the plurality of cannulated dilators, wherein the non-cannulated dilator is sized to be received within the first cannulated dilator and the first cannulated dilator is sized to be received within the second cannulated dilator.
