PROBLEM TO BE SOLVED: To provide a distal-end-deflectable/movable catheter that includes a hub joint part having excellent hub joining strength at a proximal end of the catheter, preventing the catheter tube from being easily torn, having excellent airtightness and having favorable workability, and joining method of the hub for catheter.SOLUTION: Wire rods 90 and 92 are inserted respectively into wire lumens 28a and 29a formed at a proximal end 2b of a sheath body 2. The proximal end of the sheath body 2 is enlarged at positions of the wire lumens 28a and 29b in which the wire rods 90 and 92 are inserted, to form a diameter-enlarged portion 2b1. A tip 72 of a hub 70 in which a locking protrusion 78 is formed at an outer peripheral part is inserted into the interior of a main lumen 21 of the diameter-enlarged portion 2b1. A caulking ring 80 is fitted around the outer periphery of the proximal end 2b of the sheath body 2 in which the tip 72 of the hub 70 is inserted and fixed.COPYRIGHT: (C)2016,JPO&INPIT【課題】カテーテルの近位端においてハブの接合強度に優れ、裂けにくく、気密性に優れ、作業性も良好なハブの接合部を持つ先端偏向可動カテーテルとカテーテル用ハブの接合方法を提供すること。【解決手段】シース本体2の近位端2bに形成してあるワイヤルーメン28a,29aに、それぞれ線材90,92を挿入する。線材90,92が挿入してあるワイヤルーメン28a,29aの位置で、シース本体2の近位端を拡径して拡径部2b1を形成する。拡径部2b1の主ルーメン21内部に、係止用凸部78が外周部に形成してあるハブ70の先端部72を挿入する。ハブ70の先端部72が挿入固定してあるシース本体2の近位端2b外周に、カシメ用リング80を嵌合する。【選択図】図8
