Patent ID: 8529576

Claim:
A method of injecting curable material to a delivery site within a bone structure, the method comprising: providing a delivery cannula defining: an open, proximal end, a distal segment opposite the proximal end having a distal tip, a lumen extending from the proximal end; locating a distal tip of a guide cannula within the bone structure; inserting the delivery cannula within the guide cannula; distally advancing the delivery cannula such that the distal end segment projects distal of the guide cannula distal tip, the distal end of the delivery cannula extending outside of a longitudinal axis substantially defined by the guide cannula; manipulating the delivery cannula such that at least a portion of the distal segment creates one or more voids in soft body tissue within the bone structure, where the step of manipulating is selected from: retracting at least a portion of the delivery cannula from the delivery site relative to the guide cannula and distally advancing the delivery cannula relative to the guide cannula in a reciprocating manner such that at least a portion of the distal segment creates a plurality of voids in soft body tissue within the bone structure; rotating the delivery cannula such that at least a portion of the distal segment creates one or more voids in the soft body tissue within the bone structure; and any combination thereof; and delivering the curable material to the delivery site wherein the curable material is delivered to the one or more voids in the soft body tissue created by the distal segment.
