ABSTRACT:
A flexible inner member for rotation within an angled outer tubular member of a rotary tissue cutting instrument to cut anatomical tissue includes a flexible region for conforming to the configuration of an angled region of the outer tubular member. The flexible region comprises a cut having convoluted path areas formed through a cylindrical wall of a tubular body of the inner member. The convoluted path areas are rotationally spaced on the tubular body in alternating sequence with connecting path segments of the cut. The cut follows a convoluted path in the convoluted path areas forming the wall of the tubular body into a pair of complementary, mating hook formations of opposed curvature. The connecting path segments extend rotationally along the tubular body between the convoluted path areas.
