Automatic Control Algorithm for Cardiac Output Regulation of the Total Artificial Heart (TAH)
An automatic control algorithm for the moving-actuator type total artificial heart (TAH) was developed based on motor current waveform analysis. Instead of using relatively complicated analysis of the instanta...

Orthotopic Implantation of the Tether-Free Moving-Actuator Type Total Artificial Heart in Sheep
An electromechanical total artificial heart (TAH) was developed. Its fitting trials were performed with computer simulations, and we orthotopically implanted it in 60- to 70-kg sheep in tether-free operations....

Implantable Controller with Fault Tolerance for the Moving-Actuator Total Artificial Heart (TAH): Use of a Dual Board
An implantable dual controller with fault tolerance for a total artificial heart (TAH) was developed and evaluated by in vivo studies. The TAH controller has problems normally caused by driving inductive loads...

Automatic Regulation of Output of an Electrohydraulic Left Ventricular Assist Device Using the Polymer Bellows Water Pressure and Motor Current
An electrohydraulically driven left ventricular assist device (LVAD) has been developed in our laboratory. Over years of in vitro and in vivo testing, a “suction” problem has been pointed out as one of the maj...
