Title: METHODS AND APPARATUS FOR FACILITATING DIRECT VISUALIZED RHIZOTOMY
Abstract:
Methods and apparatus for direct visual rhizotomy using an elongated tubular sheath. The sheath includes: a proximal end configured to removably receive a cannula; a distal end; a horizontal shaft having a longitudinal axis extending between the proximal end and the distal end; a first cut-away generally defining a first plane at the distal end, the first cut-away characterized by a first angle relative to a vertical plane; and a second cut-away generally defining a second plane at the distal end, the second cut-away characterized by a second angle relative to a horizontal plane. The sheath further includes an endoscope camera disposed at the distal end, the camera having a line of sight substantially orthogonal to the first plane.
