1. An apparatus comprising:
a left ventricular assist device comprising:
an impeller configured to be placed inside a left ventricle of a subject, and to pump blood from the subject's left ventricle to an aorta of the subject, by rotating;
a tube configured to traverse an aortic valve of the subject, such that a proximal portion of the tube is disposed within the subject's aorta and a distal portion of the tube is disposed within the subject's left ventricle, the distal portion of the tube being configured to allow blood to flow from the subject's left ventricle into the tube;
a frame disposed around the impeller and at least partially within the distal portion of the tube, the frame comprising struts and being configured such as to allow blood to flow into the distal portion of the tube via the struts of the frame; and
a braided element disposed distally to the impeller in an entirety thereof, the braided element configured to prevent inner structures of the left ventricle from passing into the distal portion of the tube.
