Abstract
A flexible inner tubular member for being rotated in an outer tubular member of a rotary tissue cutting instrument includes an elongate inner tube having a rotatably driveable proximal end, a distal end having a cutting member exposed from the outer tubular member to cut anatomical tissue and a flexible region allowing the inner tubular member to rotate within the outer tubular member while conforming to the shape of the outer member. The flexible region is defined by a helical cut in the inner tube defining a plurality of integrally, unitarily connected tube segments angularly movable relative to one another and a spiral wrap disposed over the helical cut.
