CATHETER

To provide a catheter high in visibility of the tip part under radioscopy, and high in periphery reachability.SOLUTION: A catheter 1 includes a tube body having an inner layer 10, an outer layer 30, and a reinforcement body 20 disposed outside the inner layer 10, which braids a plurality of strands 25 including radiopaque strands 26 and 27. The tube body includes a marker part 23 including a multi-row coil wound in a coil form with at least two strands 25 including the radiopaque strands 26 and 27 made parallel to each other more on a tip side than the reinforcement body 20. In the marker part 23, the pitch angle of the strands 25 is smaller than the pitch angle of the strands 25 in the reinforcement body 20.SELECTED DRAWING: Figure 5 【課題】放射線透視下における先端部の視認性が高く、抹消到達性の高いカテーテルを提供する。【解決手段】内層１０と、外層３０と、内層１０の外側に配置され放射線不透過性素線２６、２７を含む複数の素線２５を編組した補強体２０と、を備える管体を有するカテーテル１であって、管体は、補強体２０よりも先端側に、放射線不透過性素線２６、２７を含む少なくとも２本の素線２５を並行させた状態でコイル状に巻回した多条コイルを含むマーカー部２３を有し、マーカー部２３は、素線２５のピッチ角が補強体２０における素線２５のピッチ角より小さいカテーテル１である。【選択図】図５
