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 and formed of a labyrinthine cut through a cylindrical wall of a tubular body of the inner member. The labyrinthine cut includes a plurality of labyrinthine areas rotationally spaced on the tubular body and in which the labyrinthine cut defines a labyrinth configuration including minor curves of opposed curvature respectively arranged within major curves of opposed curvature, with each of the minor curves being continuous with a major curve of opposed curvature thereto.
