Abstract:
1. A cannula comprising: a) a rigid proximal portion connected to a malleable distal portion; b) a first polymeric lumen and at least a second polymeric lumen within and extending between the rigid proximal portion and malleable distal portion; c) the first polymeric lumen having a malleable reinforcement member within and extending along the length of the malleable distal portion; and d) the at least second polymeric lumen being in fluid communication with a fluid supply; wherein the connected malleable distal portion and rigid proximal portion can be inserted and maneuvered into a human nasal cavity, the rigid proximal portion prevents or discourages cannula bending if maneuvering in such cavity, the malleable distal portion has a durometer such that the malleable distal portion does not kink when bent greater than 45 degrees, and the malleable reinforcement member is sufficiently stiff so that the malleable distal portion will retain its shape until bent into a new shape.
