Aiming to contribute an improvement of medical robot technology, the authors have been developing a new evaluation method on cardiac function, which is based on surface measurement of the heart. This system will be able to evaluate a function of surgical robot in the future. As the preliminary study, an animal experiment was performed to examine various cardiac functions under normal pulsatile and...
A total artificial heart (TAH) is not connected to the central nervous system, and then the TAH system has to determine an adequate operation by itself. Pressure and flow rate are important indices for the decision, however, embedded pressure and flow sensors tend to cause thrombus formation and their durability is insufficient. To avoid this problem, we studied the flow rate and pressure head estimation...
