BACKGROUND Right heart dysfunction confers significant morbidity and mortality after left ventricular assist device implantation and historically occurs in as many as a third of patients. It is unknown whether newer axial flow pumps have a different impact on postimplant right heart dysfunction. We compared the incidence of right heart dysfunction after implantation of the pulsatile HeartMate I...

Continuing in vivo trials are being conducted at the University of Pittsburgh using the Nimbus axial flow blood pump (AxiPump). To date, 14 sheep experiments have been performed to address several issues related to short-term support. Six acute experiments (< 6 hr) have been performed to assess hemodynamics related to speed regulation and to determine anatomic placement of the pump and cannulae...

This paper describes a skill assist method for sinusoidal motions using a semi-active assist mechanism through an energy control method. In a previous study, we had developed and verified the effectiveness of a power assist device with a semi-active assist mechanism and a control method for reducing loads during periodic motion. Here, we have developed a skill assist method as an extension of o...
