摘要：
A guide wire-catheter assembly includes a catheter tube having a longitudinal channel, and a guide wire configured to be movable in the longitudinal channel. The catheter tube includes a bendable part near its distal end. The bendable part includes, in the circumferential direction of the catheter tube, a varying flexibility, such that exerting a longitudinal compression force in a proximal direction at a compression location distally of the distal end part results in bending of the bendable part. The guide wire includes an expandable part, where the expandable part is movable between a non-expanded position, in which a cross section of the expandable part is smaller than a smallest cross section of the longitudinal channel of the catheter tube and an expanded position. When the expandable part is in the non-expanded position, the guide wire can be moved completely in and out of the longitudinal channel of the catheter tube.
