The invention concerns a device (A) that can be used to create a new channel to conduct fluid from a fluid-conducting catheter to a blood vessel without contact between the device (A) or the catheter and the blood flow in the blood vessel. The device (A) comprises of an outer essentially tube-like part (1) with a first (3) and a second (4) end, and an inner essentially tube-like part (2) with a first (5) and a second (6) end. The tube-like parts are joined with essentially parallel axes and connected to each other close to the first end (3) of the outer tube-like part (1) and at the intermediate part (7) of the inner tube-like part (2). The outer tube-like part (1) has a lengthwise slit along part of its length from the second end (4) to let part of the blood vessel enter. The first end (5) of the inner tube-like part (2) is arranged to be conncted to the catheter and teh second end (6) of teh inner tube-like part (2) is wholly or partly surrounded by the outer tube-like part (1). The invention also concerns the use of such a device to connect a CSF conducting catheter to the deep neck vein of a human and applicator device and a support instrument facilitating the surgical procedure of applying the device (A).
