Abstract: A catheter is disclosed, which includes an inner tube, and a coil tube disposed on an outer peripheral side of the inner tube, the inner tube being a coil obtained by winding a wire. In addition, in the coil tube, a first coil and a second coil are arranged concentrically with each other. The first coil and the second coil have mutually different winding directions of the wire. Then, the inner tube and the coil tube are rotatable relative to each other around a central axis of the coil tube. In addition, in a natural state where no external force is applied to the catheter, a gap is formed between the inner tube and the coil tube.

Abstract: A medical instrument is disclosed having a structure capable of preventing liquid circulation between an inner layer side and an outer layer side of a peripheral wall portion. The medical instrument includes a main body portion in which a center hole and a radially outward space are partitioned by a tubular peripheral wall portion. The peripheral wall portion includes at least a first layer on which a hydrophilic member, in which a hydrophilic coating is formed on a first base portion, is disposed and a second layer on which a hydrophobic member, in which a hydrophobic coating is formed on a second base portion, is disposed. The peripheral wall portion is configured by the first layer and the second layer being stacked along a radial direction. As a result of swelling of the hydrophilic coating, the adjacent hydrophilic members come into contact with each other.
