Abstract: Apparatus and methods are described including an axial shaft configured for insertion into, and rotation within, a subject's body. A delivery tube extends to the axial shaft, from outside the subject's body, while the axial shaft is within the subject's body. An impeller is coupled to the axial shaft such that, as the axial shaft rotates, the impeller pumps blood of the subject. Proximal and distal radial bearings surround the axial shaft, proximally and distally to the impeller respectively, the proximal and distal radial bearings being configured to radially stabilize the axial shaft while the axial shaft rotates. A proximal bearing housing houses the proximal radial bearing and is coupled to the delivery tube. A drive cable rotates the axial shaft while extending through the delivery tube, and is coupled to the axial shaft within the proximal bearing housing. Other applications are also described.
