Abstract
A curable material delivery cannula device is disclosed. The device includes a cannula and a hub. The cannula includes an open proximal end, a deflectable segment forming a pre-set curve, a lumen, and side orifice(s) adjacent, and proximally spaced from, the distal end and fluidly connected to the lumen. When inserted within a guide cannula, the deflectable segment straightens. When distally extended from the guide cannula, the deflectable segment reverts to the curved shape. The distal end has 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. The device may be used to create voids for receiving curable material, and may include spacers configured to control location and/or orientation of the voids.
