Abstract: An actuation element guide for a surgical instrument comprises a first piece, a second piece, at least one guide channel defining a twisted path about a longitudinal axis of the guide. The guide channel may be between the inner piece and the outer piece. A cross-section of the at least one guide channel, at a location along an axial length of the guide, may be defined by a surface portion of the first piece and by a surface portion of the second piece. Exemplary embodiments further regard medical devices including an actuation element guide and methods of manufacturing an actuation element guide.
