Zusammenfassung:	To sufficiently secure column strength for effective puncture and hardly cause compression in the length.SOLUTION: A device may include a catheter 200 and a support tube 210. The catheter includes a lumen extending through it. The catheter is sized and shaped to extend through an endoscopic shaft to a target tissue within a living body. The lumen is sized and shaped for receiving a puncturing device through it. The catheter includes a first catheter portion. The first catheter portion is distal to a second catheter portion. The first catheter portion is formed as a braid polymer tube 204. The second catheter portion is formed of metal 206. The first catheter portion has a flexible curved distal end. The device includes a support tube. The support tube is fixed about an outer surface of a proximal end of the first catheter portion and an outer surface of a distal end of the second catheter portion.SELECTED DRAWING: Figure 3 【課題】効果的な穿刺のためのコラム強度を十分に確保し、長さに圧縮されにくくすること。【解決手段】装置は、カテーテル２００と支持管２１０を含み得る。カテーテルは、それを通って延びるルーメンを含む。カテーテルは、内視鏡シャフトを通って生体内の目標組織まで延びるように寸法と形状が設定される。ルーメンは、それを通して穿刺装置を受け入れるための寸法と形状に設定される。カテーテルは第１のカテーテル部分を含む。第１のカテーテル部分は第２のカテーテル部分の遠位にある。第１のカテーテル部分は編組ポリマーチューブ２０４として形成される。第２のカテーテル部分は金属２０６で形成される。第１のカテーテル部分は柔軟な湾曲した遠位端を有する。装置は支持管を備える。該支持管は、第１のカテーテル部分の近位端の外面と前記第２のカテーテル部分の遠位端の外面の周りに固定される。【選択図】図３
