Abstract: A method of managing a speed of implantable blood pump. The implantable blood pump is in communication with an internal battery and a transcutaneous energy transfer system (TETS). The method includes starting the pump at a programmed set speed. The speed of the pump is decreased from the programmed set speed to a minimum set speed if either a capacity of the internal battery is less than a predetermined reserve level and TETS power is unavailable, or there is insufficient TETS power to maintain the programmed set speed. The speed of the pump is progressively decreased from the programmed set speed if there is insufficient power to maintain the programmed set speed.

Abstract: Monolith structures coated with porous solids are provided that can serve as structural materials for amine sorbents, such as polyamine sorbents. By using monolith structures that are coated with suitable porous solids, the sorption capacity of an amine sorbent material that is deposited on the monolith coated with the porous solid can be substantially maintained as the loading density of the amine is increased. This can allow for higher productivity sorption systems by allowing higher concentrations of amine to be effectively used while still substantially maintaining the favorable sorption characteristics of the amine sorbent.

Abstract: A system includes an implantable medical device and processing circuitry. The implantable medical device includes an accelerometer and sensing circuitry. The processing circuitry obtains, during a calibration period, a first motion signal from the accelerometer. The processing circuitry determines a motion threshold based on the first motion signal. The motion threshold relates to an amount of motion of the patient that is significant for treatment of the health condition of the patient. The processing circuitry obtains, during a collection period, a second motion signal from the accelerometer. Responsive to the second motion signal satisfying the motion threshold, the processing circuitry stores data related to the treatment of the health condition of the patient.
