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 distal opening at or near the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, and having a curved distal end configured to be extended laterally outward from the distal opening in a curved path extending away from the trocar. The curved 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.
Claims14
A system configured for navigation and treatment within a vertebral body, the system comprising:
- an introducer, the introducer comprising a proximal handle and an elongate tube comprising a channel extending from the proximal handle to a distal end of the introducer;
- a straight stylet configured to be received in the channel of the introducer,
- wherein the straight stylet comprises a sharp-tipped distal end that, when installed fully within the introducer, extends slightly beyond the distal end of the introducer,
- a steerable probe configured to be inserted through the introducer after removal of the straight stylet, wherein the steerable probe comprises:
- a proximal handle;
- an elongate tube, the elongate tube comprising a slotted distal portion configured to bend upon actuation,
- a pair of electrodes configured to act as a bipolar pair;
- and
- at least one temperature sensor.
A system configured for navigation and treatment within a vertebral body, the system comprising:
- an introducer comprising a proximal end, a distal end and a central channel;
- wherein the central channel is disposed along a central axis of the introducer and extends from the proximal end toward the distal end;
- wherein the introducer comprises a distal opening at or near the distal end of the introducer, the distal opening being in communication with the central channel;
- and
- a treatment probe;
- the treatment probe sized to be received in said central channel and delivered from the proximal end of the introducer toward said distal opening of the introducer;
- the treatment probe comprising a straight proximal end and a curveable distal end;
- the curveable distal end being deformable so as to be delivered in a straight configuration through the introducer and deployed in a curved configuration outward from the distal opening of the introducer at an angle with respect to the central axis of the introducer,
- wherein the curveable distal end comprises a sharpened distal tip configured to channel through a cancellous bone region of the vertebral body;
- and
- wherein the curveable distal end comprises a pair of electrodes configured to deliver a therapeutic dose of energy to a treatment location within the vertebral body.
