Abstract:
A multilayer body, a multilayer hollow body, and a catheter with a multilayer hollow body each have improved torque transmissibility to one end when the other end is rotated rightward or leftward. The multilayer hollow body includes a single-strand hollow body that is formed by winding one element wire, an inner multi-strand hollow body that is disposed adjacently to an inner periphery of the single-strand hollow body and is formed by winding a plurality of element wires in an opposite direction from the single-strand hollow body, and an outer multi-strand hollow body that is disposed adjacently to an outer periphery of the single-strand hollow body 7 and is formed by winding a plurality of element wires in an opposite direction from the single-strand hollow body.
