A rapid exchange catheter device comprising: an elongated collapsible catheter body with a distal end and a proximal end, having a duct along a portion of the distal end of the elongated body for engagement with a guide-wire, and having a lumen extending from the proximal end towards the distal end, a portion of the lumen at the distal end substantially parallel to at least a portion of the duct; and a stiffening insert for inserting inside the lumen up to a distal end of the lumen, so as to allow advancing the catheter by advancing the stiffening insert, which pushes the distal end of the elongated body at the distal end of the lumen, dragging the rest of the catheter behind it. |
