This invention is directed to a handle (70) for manipulating a catheter tip (10)of a catheter insertion system (100), with which a self-expandable heart valvestent (150) can be inserted into the body of a patient. The invention further concernsa catheter system (30) of a catheter insertion system (100) as well as a catheterinsertion system (100) itself. The proposed catheter insertion system (100)is designed to enable the implantation of a heart valve prosthesis (160) attachedto a heart valve stent (150) in the optimum implantation location in a sequenceof events defined before the intervention. For this purpose, the catheter insertionsystem (100) comprises the handle (70) for manipulating the catheter tip (10)of the catheter insertion system (100), wherein the handle (70) comprises means(71, 81) that prescribe a pre-set sequence of steps such that each subsequentstep is inhibited until the preceding step has been completed.
