The tunneller comprises a tunnelling rod and a handle, which are detachable from each other and can be connected by the use of a safety mechanism. The rod is available in four different lengths (300, 450, 600 and 700 mm), each in two degrees of bendability (standard and rigid). This variety makes it possible to respond individually to the anatomical characteristics of the patients, such as body size and the condition of the tissue. In addition, the design of the tips allows an easy connection of the catheter for direct placement.

The ergonomically designed handle of the tunneller also offers flexibility in use. It can be held longitudinally or transversely; the adjustment according to personal preference is made easily and quickly by using the safety mechanism and is also possible intraoperatively. A click-feedback of the integrated mechanism after correct adjustment provides the desired reliability during tunnelling.
