FIELD: medical engineering. SUBSTANCE: device has flexible cannula having inlet openings for sucking blood and electric drive connected to each other. The electric drive has two links connected in series, each having flexible union member manufactured as a spring filled with vibration-damping material and elastic protection casing and electromotor. Flexible union of one of links is connected to pump unit, the electromotors being connected to electric power supply source. Pump- and electromotors shafts are hollow. The flexible union members have central opening for guiding pigtail to come through them allowing the members to be detachable from the device, which distal end projects from the flexible cannula end piece. EFFECT: low invasiveness in introducing the device into patient heart. 2 dwg
