FIELD: medicine.
SUBSTANCE: invention relates to medical pumps and is intended for introduction into the blood circulation system of a mammal in order to support the heart in the blood circulation realisation. A catheter pump contains a hollow catheter, a drive rod, placed in a lumen of the hollow catheter, a drive shaft, connected to the distal end of the drive rod for bringing it into motion by means of the drive rod, proximal and distal cases, a group of threads, stretched between the proximal and distal cases, and a propeller, installed on the drive shaft between the proximal and distal cases. Distal and proximal bearings bear the drive shaft and are installed in the distal and proximal cases. A system of washing is intended for the liquid supply by the hollow catheter to the proximal bearing in order to wash and lubricate it. Means for washing and lubrication of the distal bearing is made in a form of channels for supply of liquid from the proximal bearing to the distal one.
EFFECT: technical result consists in an increased service term.
