<p>The invention is directed to a catheter introducer device, comprising: a sheath portion (2) including a sheath (5) and a first hollow hub (4) fitted to a proximal end of said sheath (5) which is adapted to be inderted into blood vessels (18); a dilator (3) including a tube (7) detachably insertable into said sheath (5), and a second hub (6) fixed to a proximal end of said tube (7) which is adapted to guide a guide wire therethrough; first means for preventing relative axial movement of said sheath portion (2) and said dilator (3) when said tube (7) is inserted into said sheath (5) and second means for preventing relative circumferential rotation of said sheath portion (2) and said dilator (3) when said tube is inserted into said sheath (5), said first and second means being arranged betweeen said first and second hubs (4,5). In accordance with the invention said first and second means (9,10,11,12) are adapted to safely prevent relative axial movement and circumferential rotation of the sheath portion relative to the dilator.</p> |
