A Clinical Use of the Kyocera Gyro C1E3 Centrifugal Pump

Abstract

The Kyocera Gyro C1E3 centrifugal blood pump was clinically applied for a cardiopulmonary bypass (CPB) of coronary artery bypass grafting (CABG). The patient was 72-year-old male with postinfarction unstable angina. The surgery was carried out on November 20, 1998. The air inside the pump was easily and quickly removed, and its controllability was excellent. The pump flow during operation was maintained 2.2 L/m2. Total CPB time was 173 min. Perioperative parameters of hemolysis and cytotoxicity were not remarkably changed. Macroscopically and microscopically, there were no thrombi inside the pump after usage. This is the first reported case of clinical use of the Kyocera Gyro C1E3 pump.

Use of a ventricular assist device as a bridge to transplantation in a patient with single ventricle physiology and total cavopulmonary anastomosis

“…Limitations of centrifugal pump VADs are a lack of pulsatile pressure in many of the currently used models, limited support time, manpower issues and the requirements for patient immobility and ongoing hospital admission. However, there is increasing anecdotal experience in older children with pulsatile VADs designed primarily for adults 12–14 . These pumps are also totally implantable, allow for patient mobility and even hospital discharge.…”

“…However, there is increasing anecdotal experience in older children with pulsatile VADs designed primarily for adults. [12][13][14] These pumps are also totally implantable, allow for patient mobility and even hospital discharge. It is conceivable that the introduction of new paracorporeal and totally implantable devices specifically designed for all spectrum of pediatric patients will expand the short-and the long-term role of mechanical support…”

Antithrombogenic Properties of a Monopivot Magnetic Suspension Centrifugal Pump for Circulatory Assist

“…High-performance rotary blood pumps are also emerging, such as pivot-bearing centrifugal pumps without seals (Jostra Rotaflow [1], Cardiac Assist Technologies TandemHeart pVAD [2], and Japan Medical Material Gyro Pump [3]), pivot-bearing axial flow pumps (Abiomed Impeller Recover RD), and magnetic/hydrodynamic-bearing centrifugal pumps (Levitronix CentriMag and HeartWare VAD). The present monopivot pump corresponds to a pivot-bearing centrifugal pump without a seal.…”
