Catheter blood pump with deployable intra-cardiac anti-migration brace

Abstract

Catheter blood pumps that have an impeller, an outlet cage at least partially surrounding the impeller, a drive cable operatively coupled to a motor at a proximal end thereof, and operatively coupled to the impeller at a distal end thereof, a catheter, wherein the drive cable is disposed within the catheter and an anti-migration brace coupled to a component of the catheter blood pump. The anti-migration brace is configured to have a first configuration during a tortuous insertion of the catheter into a patient and a deployable second configuration that is larger than the first configuration when in position in target anatomy of the patient whereby the anti-migration brace expands laterally outwardly in size from the first configuration to the second configuration.
