In vitro detection supports protocol feasibility; leaves open clinical translation for AnyHeart pending in vivo validation.
In this paper, we describe the development of a self-management protocol for a controller of a moving-actuator type artificial heart, AnyHeart. The developed protocol analyzes motor current signals and detects abnormal pumping statuses. If preset abnormal pumping statuses are detected by an implemented algorithm, a controller triggers an emergency management procedure and transmits an alarm message to predetermined medical and engineering staffs via a cellular phone network to notify them of an abnormal pumping status occurrence and its likely cause. Results of in vitro performance experiments showed that the developed protocol can detect simulated abnormalities in motor current, manage the operating status of the blood pump during an emergency, and transmit an alarm message as desired.

Nam et al. (2006) studied this question. Self-management protocol for a moving-actuator type artificial heart (AnyHeart) was evaluated on Detection of simulated abnormalities in motor current, management of operating status, and transmission of alarm message. A developed self-management protocol for the AnyHeart artificial heart successfully detected simulated abnormalities in motor current and transmitted alarm messages during in vitro experiments.
