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 flexible elongated tube for a catheter system includes a tubing wall. The wall has a plurality of first indentations spaced apart from each other along a longitudinal axis (L) of the tube and a plurality of second indentations spaced apart from each other along the longitudinal axis (L). An axially aligned pair of indentations has a non-impressed section between the axially aligned pair of indentations. The axially aligned pair of indentations and the non-impressed section form a pull wire space.
