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.
