A device 2 for introducing a medical clement into a blood vessel is disclosed. It comprises a proximal body portion 4 connected to a distal body portion 6. The portions are connected in such a way as to allow them to switch between a first relative orientation 10 and a second relative orientation 14. When the distal body portion 6 has been inserted into the blood vessel, a medical element can be inserted into the blood vessel through the proximal body portion 4 in one axial direction 10 of the blood vessel when the proximal and distal body portions arc in the first relative orientation and in the other axial direction 14 of the blood vessel when the proximal and distal body portions arc in the second relative orientation. The medical element is preferably a catheter or a guide wire. Preferably the two portions 4, 6 are connected by a hinge and are rotatably engaged. Optionally, in the first orientation the proximal portion 4 is at a first angle relative to the distal portion 6 and, in the second orientation, the proximal portion 4 is at a second angle relative to the distal portion 6. |
