<p>A debulking catheter (20) includes a tissue debulking assembly (28) for debulking a body lumen. The catheter (20) comprises a flexible proximal portion (24) coupled to a rigid distal portion (26). The tissue debulking assembly is disposed within the rigid portion (26) to debulk the body lumen. The rigid portion (26) is rotatably coupled to the flexible portion such that rotation or deflection of the rigid portion (26), relative to the flexible portion (24), can expose the tissue debulking assembly (28) through a window (32) in the catheter (20) to debulk the body lumen.</p> |
