More Information
Summary:Apparatus and methods are described including a blood pump that includes an axial shaft configured for insertion into, and rotation within, a body of a subject. An impeller is coupled to the axial shaft such that, as the axial shaft rotates, the impeller pumps blood of the subject. A thrust bearing includes a proximally-facing ceramic surface disposed distally from the axial shaft so as to inhibit distal movement of the axial shaft beyond the thrust bearing, and a distally-facing ceramic cover that covers a distal end of the axial shaft, such that the ceramic cover contacts the ceramic surface as the axial shaft rotates. Other applications are also described.
