AI Technical Summary
Technical Problem
Conventional catheter manufacturing methods using heat-shrinkable tubing require removal of the tubing after joining, which is costly and prone to errors, leading to increased labor and material waste.
Method used
A method involving laser fusion of adjacent portions of first and second members using an elastically deformable elastic body and a hard component to bring the members into close proximity, eliminating the need for post-fusion removal of components.
Benefits of technology
Enables multiple fusions without the need for post-fusion component removal, reducing labor and material costs while ensuring stable and efficient catheter production.

Abstract
The present invention provides a catheter manufacturing method that allows for multiple fusions of a first component and a second component, such as two tubes, while eliminating the need to remove components from the product after fusion. [Solution] A method for manufacturing a catheter in which an elastic body 220 having laser light transmittance and a hollow portion through which a first member 30 and a second member 40 can be inserted with a gap when unloaded is brought close together by elastic deformation in the hollow portion, and an external force is applied to the elastic body 220 by a hard part 230 which is harder than the elastic body 220, by the hard part 230 which is positioned outside the elastic body 220 in a radial direction intersecting the axial direction of the first member 30 and the second member 40, by the close contact between the inner surface of the hard part 230 and the outer surface of the elastic body 220, and laser light is irradiated onto the adjacent portions of the first member 30 and the second member 40 to fuse the adjacent portions.
