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.
Claims31
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;
- 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.
A method for channeling a path into bone to a treatment location in the body of a patient, comprising:
- inserting a trocar into a region of bone near the treatment location;
- the trocar having a having a proximal end, distal end and a central channel disposed therebetween;
- 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;
- delivering a curveable cannula through said central channel and to said radial opening;
- and
- deploying the curveable cannula laterally outward from the radial opening in a curved path extending away from the trocar.
A spine therapy system, 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 is configured to be deployed through a cortical bone region and into a cancellous bone region of a vertebral body;
- 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 central passageway and curveable distal end configured to be extended laterally outward from the radial opening in a curved path extending away from the trocar;
- wherein the curved path is generated though at least a portion of the cancellous bone region of the vertebral body;
- and
- a treatment probe configured to be delivered through the central passageway to a location beyond the curved path.
