Abstract: A catheter device for implanting a medical implant such as a prosthetic heart valve has a handle configured to control/steer multiple sheaths of the catheter device. A handle includes a grip portion, a rotatable deployment knob and a traveler. An outer sheath is connected to the traveler and the deployment knob is operatively connected to the traveler such that the traveler and thereby the outer sheath are moved along the longitudinal axis with respect to the inner sheath. The handle includes a rotatable axial positioning knob and a rotatable deflection knob. The deployment knob is arranged proximally to the axial positioning knob.

Abstract: A catheter device for implanting a medical implant has a handle that includes a locking element configured to be moved from a first to a second state. The locking element limits a movement of a traveler and therewith of a capsule in a distal direction (D) in the first state. The locking element allows further movement of the traveler and therewith of the capsule in the distal direction in the second state.
