Devices and methods of use identification, treatment, andor management of heart failure andor associated conditions. The trial platform is essentially basin-shaped with radially inward-turned rims, at least at its free ends. The common gate output stage includes two series connected complementary pairs of transistors. In the preferred embodiment, throughput is estimated utilizing rotor variable drive actuator pressure, and a target RVDAP is modified for short periods of time in accordance with the learned correlation. In an alternate embodiment, the three separate armatures are covered with a fabric sleeve. The IO fabric elements that are dynamically configured as such are disposed within a hardware path that is defined between the non-recoverable resource and a processor that accesses the non-recoverable resource.
