In some embodiments, a system can include a fluid delivery assembly and a drive assembly. The fluid delivery assembly is configured to be releasably mechanically and, optionally, electrically coupled to the drive assembly. When the fluid delivery assembly is releasably coupled to the drive assembly, the drive assembly can control delivery of fluid from the fluid delivery assembly (e.g., to a patient). For example, the drive assembly can be releasably coupled to the fluid delivery assembly to control delivery of fluid from the fluid delivery assembly to provide continuous (e.g., non-pulsatile) fluid flow from the fluid delivery assembly.

A fluid infusion system includes a housing configured to be adhesively coupled to an anatomy of the user. The housing comprises a communication device configured to wirelessly communicate a physiological characteristic to a communication component of a fluid infusion device. The fluid infusion system includes a fluid flow path from the fluid infusion device into the anatomy of the user, and the fluid flow path is configured to extend from the housing for insertion into the anatomy of the user.

An external power transmitter of an implanted medical device system such as a left ventricular assist device (LVAD) system and a method therefore are provided. According to one aspect, a method includes transitioning from applying a first external coil current limit to applying a second external coil current limit to limit current of an external coil coupled to the external power transmitter, the transitioning being based on at least one of an intent to enter a free mode of operation of the implanted medical device system, an existence of an alarm condition, and an existence of transcutaneous energy transfer system (TETS) power transfer.

An implantable blood pump includes a control unit storing patient specific settings. The control unit is configured to store patient specific settings. The patient specific settings can be used to determine a target operating speed for the blood pump and/or a target operating mode for the blood pump. The patient specific settings can include at least one of an operating mode for the pump, a set speed for the pump, a lower speed limit for the pump, a patient hematocrit value, a patient hematocrit date, a patient blood density, and a periodic log rate for event and periodic data.

Systems, devices, and methods for improving wireless power transmission are disclosed herein. A method of powering an implantable ventricular assist device with an external charging device includes receiving a signal indicative of a change in a property of a deformable coil of the resonant circuit. A performance property of the deformable coil is determined based on the signal. An adjustment to a tuning of the resonant circuit is identified based on the performance property of the deformable coil. The resonant circuit is tuned according to the adjustment to the tuning of the resonant circuit. The resonant circuit is driven to transmit power to a secondary coil electrically coupled with the implantable ventricular assist device to power the ventricular assist device.

A respiratory apparatus includes components to permit different operations of the apparatus with different power supplies. For example, a respiratory therapy apparatus for controlling a respiratory therapy may include a power input circuit to receive a first power or a second power. The first power may be provided by a connectable low-power power supply and the second power by a connectable high-power power supply. A controller of the respiratory apparatus coupled to the power input circuit may be configured to detect one of the power supplies, and based on the detection, selectively activate one of a first mode of operation and a second mode of operation. The first mode of operation may be a non-therapy mode with the first power such as for a data setup or data transfer with the respiratory therapy apparatus and the second mode of operation may be a therapy mode with the second power.

A charging system for an Implantable Medical Device (IMD) is disclosed having a charging coil and one or more sense coils preferably housed in a charging coil assembly coupled to an electronics module by a cable. The charging coil is preferably a wire winding, while the sense coils are preferably formed in one or more traces of a circuit board.

Knowing the position, the power of the magnetic field produced by the charging coil can be adjusted to compensate for the position.
