6. A method of injecting curable material within a bone structure, the method comprising:

  • providing a delivery cannula defining;

    an open, proximal end, a deflectable segment opposite the proximal end having a distal end, a lumen extending from the proximal end, wherein the deflectable segment has a shape memory characteristic and naturally assumes a curved shape in longitudinal extension;

    locating a distal tip of a guide cannula within the bone structure;

    inserting the delivery cannula within the guide cannula, characterized by the deflectable segment deflecting to a substantially straightened shape within the guide cannula;

    distally advancing the delivery cannula such that the distal end and at least a portion of the deflectable segment projects distal the distal tip, characterized by the portion of the deflectable segment distal the distal tip naturally reverting to the curved shape;

    positioning the distal end distally adjacent a first region within the delivery site;

    delivering the curable material to the first region within the delivery site;

    positioning the distal end distally adjacent a second region within the delivery site; and

    delivering the curable material to the second region within the delivery site.
