Abstract: A wand-like tool (20) for a hand blender comprises an elongate, tubular housing (22) containing a rotatable drive shaft (23). The tool is adapted at one end to permit the shaft (23) to pick up rotary drive from a hand-held driver unit, and carries a foodstuff-processing head at its other end; the processing head comprising a bladed member (26), coupled to the shaft (23) and having at least three blades (32a, 32b, 32c). The bladed member rotates within a processor head housing (27) having a tubular side-wall (30) formed with a roof (36) where the processor head housing (27) joins the tubular shaft housing (22) and being open at its opposite end, and the internal surface (38) of the side-wall (30) bears protrusions (40) facing the tips of the blades (32a, 32b, 32c). Each protrusion (40) presents a respective bluff body to foodstuffs flowing past it.

Abstract: Described here are paranasal sinus devices for treating paranasal sinus conditions. The devices include a cavity member, ostial member, and nasal portion. One or more of the cavity member, ostial member, and nasal portion may deliver an active agent for sustained release to treat the paranasal sinus condition. Exemplary paranasal sinus conditions are sinus inflammation due to functional endoscopic sinus surgery (FESS) and rhinosinusitis.
