Patent attributes
A sinuplasty tool, consisting of a handle, and a rigid tube, containing a rigid tube lumen, having a rigid tube distal end and a rigid tube proximal end connected to the handle. The tool also has a resilient tube, containing a resilient tube lumen, having a resilient tube distal end and a resilient tube proximal end fixed to the rigid tube distal end so that the lumens align. The resilient tube has a multiplicity of separated openings partially encircling the resilient tube so as to form ribs in the resilient tube and permitting the resilient tube to bend. The resilient tube distal end may be inserted into a sinus of a living subject. The tool also has a wire, traversing the aligned lumens, connected to the resilient tube distal end and coupled to the handle, so that applying tension to the wire causes the resilient tube to bend.
