Abstract:
1. A fixing device configured for mounting to a shaft of a catheter and arbitrarily changing the mounting position and fixing thereof, the fixing device comprising: a tubular member having a hollow part permitting the shaft to be inserted and passed therein, the tubular member being configured such that the hollow part is enlarged by contraction of the tubular member in an axial direction and reduced by extension of the tubular member in the axial direction; a first projection and a second projection which are provided on an outer circumferential portion of the tubular member at positions spaced from each other in the axial direction of the tubular member; a movable tubular body which is disposed around the tubular member between the first projection and the second projection, the tubular body being configured for movement in the axial direction relative to the tubular member within a range restricted by the first projection and the second projection; and a distal part coupled with the movable tubular body by a support part, the distal part being disposed distally of the tubular member, the distal part being configured to contact a proximal portion of a tubular device for medical use in a configuration wherein the fixing device is mounted to the catheter, and the catheter is inserted and passed in a lumen of the tubular device for medical use.
