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.

Claims

1. 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 central channel and opening at its distal tip; and

delivering a cannula through said central channel and to said opening;

wherein the cannula comprises a deflectable tip with a preformed curve such that the tip straightens while being delivered through the trocar curves upon exiting the trocar;

extending the cannula past the distal opening of the trocar to generate a curved path in the bone corresponding to the preformed curve of the deflectable tip; and

delivering a treatment device through a central passageway in said cannula to the treatment location beyond the curved path.
