The bypass element delivery system (52, 53, 8) is moveable along the first guide wire (30) and the bypass element delivery system (52, 53, 8) is capable of releasing and setting free the bypass element (6, 7). The kit further comprises an expansible element (40) being capable of connecting with the bypass element delivery system (52, 53, 8), of moving the bypass element delivery system (52, 53, 8) towards the opposite end of the first guide wire (30) and of setting the bypass element delivery system (52, 53, 8) free. The inventive kit enables an atraumatic placement of a bypass.

Abstract: The invention relates to a delivery system for delivering a stent (S) into a body vessel of a patient, comprising a flexible catheter tube (3) having a proximal and a distal end for delivering the stent (S) to a predetermined location in the body vessel and a catheter tip (1) having a longitudinal direction, which is disposed at the distal end of the catheter tube (3). The catheter tip (1) has a stent chamber (150) to receive the stent (1). The catheter tip has a first pressure chamber (20, 22). In the catheter tube (3) a first fluid channel (31) extends from the proximal end to the first pressure chamber (20, 22) of the catheter tip (1). The volume of the first pressure chamber (20, 22) can be enlarged by delivering a first fluid from the first fluid channel (31) to the first pressure chamber (20, 22), such that the stent (S) is released from the stent chamber (150) at the predetermined location in the body vessel.
