Abstract

A catheter (1) comprising an elongate tubular body (2) having a proximal end (3), a distal end (4), and an inner lumen (5) extending through the elongate tubular body (2), wherein the elongate tubular body (2) comprises a proximal section (6) and a distal section (7), wherein at least the proximal section (6) comprises at least two layers, wherein the proximal end (3) is connected with a catheter hub (8) being an adapter of greater radial outside dimension than the elongate tubular body (2), wherein the catheter hub (8) has an inner lumen (9) of larger inside diameter than the elongate tubular body (2), and wherein the innermost layer (10) of the proximal section (6) extends into the catheter hub (8) and flares from the proximal section (6) to the catheter hub (8). The catheter ensures a smooth transition of a medical device, e.g. a stent to be transferred from a storage device like a sheath into the tubular body of the catheter.
