A curable material delivery cannula device (26) is disclosed. The device includes a cannula (36) and a hub (34). The cannula includes an open proximal end (80), a deflectable segment (88) forming a pre-set curve (90), a lumen (86), and side orifice(s) (84) adjacent, and proximally spaced from, the distal end (82) and fluidly connected to the lumen. When inserted within a guide cannula (22), 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 (100) 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. |
