Abstract
A catheter pump comprising a pump head for insertion into the aorta. The pump head includes: a rotor having propellers that can be displaced from a folded insertion position in which the pump head can be inserted into the aorta, to an unfolded operating position in which the rotor can be set in rotation, and a cage surrounding the propellers. The cage comprises a distal, proximal sheath and filaments running between sheaths. The sheaths are moved towards one another at or before the unfolding of the propellers in a manner that the regions of the filaments lying between the sheaths expand radially outward, to form a space surrounding the unfolded propellers. At least some or all of the filaments are configured so as to each have at least one main section that engages one sheath and splits into at least two minor sections in the direction toward the other sheath.
