An external drive unit for an implantable heart assist pump is provided. The drive unit comprises a motor housing, a transcutaneous drive shaft and a motor for driving the heart assist pump. The motor is connectable to the heart assist pump via the drive shaft, and the motor is arranged inside the motor housing. The drive unit further comprises a catheter surrounding the drive shaft and a purge line for injecting a purge medium into a lumen of the catheter or into a space between the catheter and the drive shaft. The purge line is in thermal contact with an outer surface of the motor housing and/or with an outer surface of a proximal section of the catheter. Due to the thermal contact heat is transferred from the outer surface of the catheter in the proximal section and/or from the outer surface of the motor housing to the purge medium.

External drive unit for an implantable heart assist pump

The application relates to an external drive unit () for an implantable heart assist pump. The proposed drive unit () comprises a motor () for driving the heart assist pump, wherein the motor () is connectable to the heart assist pump via a transcutaneous drive shaft (). The drive unit () further comprises a heat spreader () comprising a contact surface configured to contact and/or directly contact and/or lie flat against a skin of a patient. The contact surface is connected or connectable with the motor () in a thermally-conductive manner to transfer heat generated by the motor () to tissue of the patient.

An intravascular blood pump has an intake filter that reduces risk of heart tissue being sucked into an intake port of the pump. The filter defines a plurality of apertures, through which blood flows through the filter. The apertures are sized to prevent ingestion, by the input port, of the heart tissue. The filter includes a plurality of generally helical first struts wound about a longitudinal axis of the filter, and a plurality of second struts. The first and second struts collectively define the plurality of apertures therebetween. The struts may be woven filaments, or the apertures may be defined in a thin film (foil) tube, where remaining material between the apertures form the struts.
