PROBLEM TO BE SOLVED: To provide a renal artery catheter that can be inserted into right and left renal arteries easily and in a short period of time without much skill in the insertion work.SOLUTION: A main tube 11 having a pair of lumens is provided with a deflecting operation part 23 on the proximal end and with a pair of end tubes 32, 33, which respectively communicate with the pair of lumens in the main tube 11, on the distal end. One end tube 32 is connected to the deflecting operation part 23 (23a, 23b) through a pair of wires which are inserted into a pair of sub-lumens provided in the main tube. By performing the rotation operation of the deflecting operation part as shown by an arrow B1 or B2, the vicinity of the distal end of the end tube 32 is deflected as shown by an arrow C1 or C2.COPYRIGHT: (C)2015,JPO&INPIT【課題】左右の腎動脈への挿入作業をそれほどの熟練がなくても、短時間で容易に行い得る腎動脈カテーテルを提供する。【解決手段】一対のルーメンを有するメインチューブ11の近位端に偏向操作部23を、遠位端にメインチューブ11の一対のルーメンにそれぞれ連通する一対の先端チューブ32,33を配置し、一方の先端チューブ32はメインチューブに設けられた一対のサブルーメン内に挿通された一対のワイヤを介して偏向操作部23(23a,23b)に接続されており、偏向操作部を矢印B1又はB2のように回転操作することにより、先端チューブ32の遠位端近傍を矢印C1又はC2のように偏向させるようにした。【選択図】図1
