VERTEBRAL BONE NAVIGATION SYSTEMS
First Claim
1. A system for channeling a path into bone, comprising:
- a trocar having a proximal end, distal end and a central channel;
wherein the central channel is disposed along a central axis of the trocar and extends from the proximal end toward the distal end;
wherein the trocar comprises a radial opening at or near the distal end of the trocar, the radial opening being in communication with the central channel;
a curveable cannula sized to be received in said central channel and delivered from the proximal end toward said radial opening;
the curveable cannula comprising a curveable distal end configured to be extended laterally outward from the radial opening in a curved path extending away from the trocar;
wherein the curveable cannula comprises a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path,wherein the distal end of the curveable cannula is deformable so as to be delivered in a straight configuration through the trocar and deployed in a curved configuration outward from the radial opening at an angle with respect to the central axis; and
a pull cord coupled to the distal tip of the curveable cannula, the pull cord extending to the proximal end of the trocar;
wherein the pull cord is configured to apply a tensile force to the distal end of the curveable cannula to bias the curveable cannula into a curved configuration.

Abstract
System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a radial opening at or near the distal end of the trocar. The system includes a curveable cannula sized to be received in the central channel, the curveable cannula comprising a curveable distal end configured to be extended laterally outward from the radial opening in a curved path extending away from the trocar. The curveable cannula has a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path.

21. A system for channeling a path into bone, comprising:
-
a trocar having a proximal end, distal end and a central channel; wherein the central channel is disposed along a central axis of the trocar and extends from the proximal end toward the distal end; wherein the trocar comprises a radial opening at or near the distal end of the trocar, the radial opening being in communication with the central channel; wherein the trocar further comprises a sharp distal tip configured to pierce through bone to generate a linear path through bone; and a curveable cannula sized to be received in said central channel and delivered from the proximal end toward said radial opening; the curveable cannula comprising a curveable distal end configured to be extended laterally outward from the radial opening in a curved path extending away from the trocar; wherein the curveable cannula comprises a central passageway having a diameter configured allow a probe to be delivered through the central passageway to a location beyond the curved path, and wherein the curveable cannula comprises a sharpened distal tip configured to pierce through bone to generate a curved path extending from a linear path generated by the trocar. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
