Abstract
A flexible catheter with a drive shaft, and associated devices and systems. In some examples, the disclosure describes a flexible catheter with a drive shaft, with a sleeve surrounding the drive shaft and with a sheath surrounding the drive shaft and the sleeve, wherein the drive shaft, the sleeve and the sheath are pliable, wherein the drive shaft at a proximal end of the drive shaft comprises a coupling element for connecting the drive shaft to a drive motor, wherein the drive shaft at least regionally consist of a alloy which contains at least 10% by weight of chromium, nickel and cobalt in each case.
Claims25
A flexible catheter comprising:
- a drive shaft;
- a sleeve surrounding the drive shaft;
- and
- a sheath surrounding the drive shaft and the sleeve, wherein the drive shaft, the sleeve and the sheath are pliable, wherein the drive shaft at a proximal end of the drive shaft comprises a coupler configured to connect the drive shaft to a drive motor;
- a pump rotor coupled to the drive shaft and configured to produce a flow when the pump rotor is rotated in a given direction;
- and
- a thrust bearing configured to counteract an axial displacement of the drive shaft resulting from the pump rotor being rotated in the given direction, the thrust bearing comprising at least a first bearing element and a second bearing element, the first bearing element connected to the drive shaft.
