<p>Abstract A curable material delivery cannula device (26), a cannula (36) and a hub (34). The cannula (36) has an open proximal end (80), a deflectable 5 segment (88) forming a pre-set curve, a lumen (86), and side orifice(s) (84) adjacent, and proximally spaced from, the distal end (82) and fluidly connected to the lumen (86). When inserted within a guide cannula, the deflectable segment (88) straightens. When distally extended from the guide cannula, the deflectable segment (88) reverts to the curved shape. The distal end (82) has 10 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) (84) in a radial direction relative to the lumen. 11a0 11 26 90 110c 110b 110a 36 Fig. 1</p> |
