Spine treatment kits
First Claim
1. A kit for therapeutically treating multiple different vertebrae in a spine, the kit including:
- a trocar having a central channel and an opening at a distal tip of the trocar; and
a set of cannulas sized to be received in said central channel of the trocar and delivered to said opening at the distal tip of the trocar;
each cannula of the set of cannulas comprising a deflectable distal end portion with a preformed curve such that the deflectable distal end portion straightens while being delivered through the central channel of the trocar and transitions to a curved configuration upon exiting and extending past the opening at the distal tip of the trocar to generate a curved path in a vertebral body corresponding to the curved configuration of the deflectable distal end portion;
a set of curved stylets, each curved stylet sized and configured to be introduced within a respective cannula of the set of cannulas, wherein a distal end portion of each curved stylet has a preformed curve corresponding to the preformed curve of the respective cannula; and
a radiofrequency energy delivery probe adapted to be delivered through a respective cannula of the set of cannulas such that an active element of the radiofrequency energy delivery probe is positioned at a location in the vertebral body beyond the curved path,wherein each cannula of the set of cannulas comprises a central passageway having a diameter configured to allow the radiofrequency energy delivery probe to be delivered through the central passageway to the location beyond the curved path after removal of the respective curved stylet,wherein the deflectable distal end portion of each cannula of the set of cannulas has a different preformed curvature adapted to facilitate access to a respective vertebra of the spine,wherein a first cannula of the set of cannulas comprises a first preformed curvature configured to facilitate access by the radiofrequency energy delivery probe to a first vertebra, andwherein a second cannula of the set of cannulas comprises a second preformed curvature configured to facilitate access by the radiofrequency energy delivery probe to a second vertebra different from the first vertebra.

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 the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, the curved cannula comprising a curved distal end configured to be extended outward from the distal opening to generate a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured to allow a treatment device to be delivered through the central passageway to a location beyond the curved path.

12. A kit for therapeutically treating multiple different vertebrae in a spine, the kit including:
-
an introducer having a central channel and an opening at a distal tip of the introducer; and a plurality of cannulas sized to be received in said central channel of the introducer and delivered to said opening at the distal tip of the introducer; each cannula comprising a deflectable distal end portion having a preformed curve such that the deflectable distal end portion straightens while being delivered through the central channel of the introducer and transitions to a curved configuration upon exiting and extending past the opening at the distal tip of the introducer to generate a curved path in a vertebral body corresponding to the curved configuration of the deflectable distal end portion of the cannula; a set of curved stylets, each curved stylet sized and configured to be introduced within a respective cannula of the plurality of cannulas, wherein a distal end portion of each curved stylet has a preformed curve corresponding to the preformed curve of the respective cannula; and an energy device, wherein each cannula comprises a central passageway having a diameter configured to allow the energy delivery device to be delivered through the central passageway to a location beyond the curved path after removal of the corresponding curved stylet; and wherein the deflectable distal end portion of each cannula has a different preformed curvature. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
