Abstract
A curable material delivery cannula device and method are disclosed. The device includes a cannula and a hub. The cannula includes an open proximal end, a deflectable segment forming a plurality of pre-set curves, each of which corresponds to a pre-determined temperature of the cannula, a lumen, and side orifice(s) adjacent, and proximally spaced from, the distal end and fluidly connected to the lumen. When distally extended from the guide cannula, and upon being heated to a predetermined temperature (before, during, or after extension), the deflectable segment assumes a curved shape, which may be used to create a void in the bone for receiving curable material. The distal cannula end includes a blunt tip for non-traumatic interface with bodily material. During use, curable material, such as bone cement, is delivered from the side orifice(s) in a radial direction relative to the lumen.
