<p>A medical device for introducing a catheter comprises a tubular body (2) which extends in a longitudinal direction (X) and in which a single chamber (3) open at the longitudinally opposite ends is defined, a retractable needle (10) connected to the tubular body and movable inside the chamber between an operative position, in which the needle projects from the tubular body, and a non-operative position, in which the needle is accommodated inside the tubular body, and a slider (20) secured to the needle (10) and engaged for sliding on the tubular body so as to project at least partially from the tubular body in order to bring about the movement of the needle. The tubular body has a non-circular cross-section on which are identified a major axis (A) and a minor axis (B) which are substantially perpendicular to each other, and the slider projects from the tubular body parallel with the minor axis.</p> |
