Patent ID: 7713273

Claim:
A cannula device for delivering a curable material, such as bone cement, into bone as part of a curable material delivery system, the device comprising: a delivery cannula defining: an open proximal end; a lumen extending from the proximal end; a deflectable segment opposite the proximal end and terminating in a closed distal end that is axially closed to the lumen and having a blunt tip; and at least one side orifice formed adjacent to, and proximally spaced from, the distal end and that is fluidly connected to the lumen, wherein the delivery cannula lumen defines an inside diameter, and further wherein the at least one side orifice has at least one orifice dimension that is greater than the inside diameter; wherein the deflectable segment forms a curved shape in longitudinal extension and has a shape memory characteristic such that the deflectable segment is configured to assume a longitudinally, substantially straightened form when subjected to a force and to naturally revert to the curved shape upon removal of the force; and a hub forming a fluid port fluidly coupled to the proximal end, wherein the curved shape defines a bend greater than 90 degrees, and the curved shape defining an interior bend side and an exterior bend side and at least one side orifice is open relative to the exterior bend side, opposite the interior bend side.
