Abstract

Catheter blood pump positioning techniques, methods, and algorithms are described. In one embodiment, pressure sensor measurements are used to determine the distance to the aortic valve and the left ventricle. An optimal positioning location can be determined based on the pressure sensor measurements. The catheter blood pump can then be optimally positioned to locate the inlet in the ventricle and the outlet in the aorta.
