Abstract:
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; 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; a probe sized to fit within a central passageway of the curveable cannula, a drive nut coupled to the curveable cannula, wherein the drive nut comprises a threaded distal recess configured to house a proximal end of the probe, wherein the probe comprises mating threads configured to mate with corresponding threads of the threaded distal recess so as to allow controlled translation of the drive nut with respect to the probe, wherein central passageway of the curveable cannula has a diameter configured to allow the probe to be delivered through the central passageway to a location beyond the curved path, wherein the curveable cannula comprises a proximal end comprising a proximal body, wherein the proximal end of the trocar comprises a housing, said housing having a proximal recess configured to allow reciprocation of the proximal body of the curveable cannula, and wherein the proximal recess is in communication with the central channel.
