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 valve stent (150) can be inserted into the body of a patient. The invention further concerns a catheter system (30) of a catheter insertion system (100) as well as a catheter insertion system (100) itself. The proposed catheter insertion system (100) is designed to enable the implantation of a heart valve prosthesis (160) attached to a heart valve stent (150) in the optimum implantation location in a sequence of events defined before the intervention. For this purpose, the catheter insertion system (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 subsequent step is inhibited until the preceding step has been completed.

La présente invention concerne une poignée (70) permettant de manipuler une pointe de cathéter (10) d'un système d'insertion de cathéter (100), avec lequel une prothèse valvulaire cardiaque auto-dilatable (150) peut être insérée dans le corps d'un patient. L'invention concerne en outre un cathéter (30) d'un système d'insertion de cathéter (100) ainsi que le système d'insertion de cathéter (100) lui-même. Le système d'insertion de cathéter proposé (100) est conçu pour permettre l'implantation d'une prothèse valvulaire cardiaque (160) fixée sur un stent pour valvule cardiaque (150) dans un lieu d'implantation optimum selon une suite d'évènements définie avant l'intervention. A cette fin, le système d'insertion de cathéter (100) comprend la poignée (70) permettant de manipuler la pointe de cathéter (10) du système d'insertion de cathéter (100), ladite poignée (70) comprenant des moyens (71, 81) qui prescrivent une séquence d'étapes prédéfinie de telle sorte que chaque étape subséquente n'est permise que lorsque l'étape précédente est achevée.
