Title:
クロスフロー原理を使用する血液ポンプ
Document Type and Number:
Japanese Patent JP4121709
Kind Code:
B2
Abstract:
A blood pump is provided which comprises a cross-flow pump head having an elongated generally cylindrical housing portion. The housing portion defines a blood inlet port on a surface thereof and a blood outlet port on an opposite surface thereof. An impeller within the housing portion provides cross-flow of the blood from the inlet port around and/or across the rotational axis of the impeller to the outlet, and a motor is provided for driving the cross-flow pump head. The blood pump may be small enough to permit percutaneous insertion of the pump into a patient's blood vessel, and thus may be utilizable as a left ventricular assist device. To this end, a collapsible polymeric outflow tube is coupled to the blood flow outlet and is adapted for directing the blood from the left ventricle to the aorta through the aortic valve.
