PROBLEM TO BE SOLVED: To provide a reinforcing member having an excellent push-in property, torque transmission property, followability, and kink resistance, and a catheter including the reinforcing member.SOLUTION: A reinforcing member 2 extends along a drawing direction from a proximal end to a distal end, and reinforces a catheter 1. The reinforcing member 2 includes: a coiled part 3 as a tubular member formed by winding a wire strand into a coil shape, and having a lumen extending along the drawing direction from the distal end to the proximal end a netted part 4 as a tubular member formed by knitting the wire strand into a net shape, and having a lumen extending along the drawing direction from the proximal end to the distal end and a connection part for connecting a distal-side end of the coiled part 3 and a distal-side end of the netted part 4 and communicating the respective lumens with each other.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】押し込み性、トルク伝達性、追従性、及び、耐キンク性に優れた補強部材、及び、補強部材を有するカテーテルを提供する。【解決手段】補強部材2は、延伸方向に沿って基端から先端まで延び、カテーテル1を補強する。補強部材2は、素線がコイル状に巻回された管状の部材であって、内腔が延伸方向に沿って先端から基端側に延びるコイル状部3、素線が網状に編み込まれた管状の部材であって、内腔が延伸方向に沿って基端から先端側に延びる網状部4、及び、コイル状部3の基端側の端と、網状部4の先端側の端とを接合し、それぞれの内腔を連通する接合部を備えている。【選択図】図1
