1. An endovascular catheter configured for tortuous vasculature, the endovascular catheter comprising:
a catheter shaft including a first lumen and a shaft opening, wherein the first lumen is in communication with the shaft opening,
a semi-spherical deflector rotatably arranged inside the catheter shaft and configured to rotate to deflect a guidewire through the shaft opening, and
a closed-loop transmission element that is operably connected with the semi-spherical deflector and configured to rotate the semi-spherical deflector in a first rotating direction, wherein the semi-spherical deflector comprises a recess formed in a direction of a longitudinal axis of the catheter shaft, and wherein a guiding element configured to guide the guidewire is arranged at a distal end of the recess, wherein the guiding element is formed as a ring, arranged in such a way that a central axis of the ring coincides with a longitudinal axis of the recess.
