The invention relates to a handle for a catheter (1) having an inner shaft (9) and a retractable shaft (8), wherein the handle (2) has - a housing (11), - a pull cable (18) and - a release button (4) mounted movably on the housing (11). In order to avoid a winding of the pull cable around the inner shaft, a sleeve (16) is secured in the housing (11) and a brake hose (17) is guided movably in the longitudinal direction in the continuous opening (21) of said sleeve, wherein the brake hose (17) has a first continuous opening (31) for arrangement of the pull cable (18) and a second continuous opening (32) for arrangement of the inner shaft (9), wherein the brake hose (17) is designed in such a way that its position relative to the sleeve (16) in a first state is fixed by means of the release button (4), and in that the brake hose (17) in a second state is displaceable after actuation of the release button (4) together with the pull cable (18) in the longitudinal direction of the sleeve (16) and relative to the sleeve (16) and the inner shaft (9) in the proximal direction in order to retract the retractable shaft (8), wherein the retractable shaft (8) can be connected to the pull cable (18). The invention also relates to a catheter (1) with a handle (2) of this kind and to a method for operating a catheter (1) of this kind.La présente invention concerne une poignée pour cathéter (1) présentant une tige interne (9) et une tige rétractable (8), la poignée (2) présentant - un logement (11), - un câble de traction (18) et - un bouton de libération (4) monté mobile sur le logement (11). Afin d'éviter un enroulement du câble de traction autour de la tige interne, un manchon (16) est solidement fixé dans le logement (11) et un tuyau de frein (17) est guidé mobile dans le sens longitudinal dans l'ouverture continue (21) dudit manchon, le tuyau de frein (17) présentant une première ouverture continue (31) pour la mise en place du câble de traction (18) et une seconde ouverture co
