Abstract

Disclosed herein is a method of pumping blood in a patient. The method includes inserting an impeller housing and impeller into the patient, the impeller disposed within the impeller housing and having a longitudinal axis, positioning the impeller housing and the impeller at a treatment location in the patient, activating an adjustment device at a proximal end portion of the heart pump outside the patient to provide relative motion between the impeller housing and the impeller along the longitudinal axis, and pumping blood through the impeller housing along the longitudinal axis.
