Abstract
A cannula device for removing, including by aspirating, bodily material is disclosed. The device may include a cannula and a hub. The cannula includes an open proximal end and a deflectable distal segment, and one or a plurality of distal orifices fluidly connected to the lumen. When distally extended from an outer guide cannula, the deflectable segment assumes a curved shape, which includes temperature-dependent curvature subject to elevated temperature along a memory metal length of the cannula.
