Abstract: Temperature sensing circuitry for an Implantable Medical Device (IMD) is disclosed that can be integrated into integrated circuitry in the IMD and draws very little power, thus enabling continuous temperature monitoring without undue battery depletion. Temperature sensor and threshold setting circuitry produces analog voltage signals indicative of a sensed temperature and at least one temperature threshold. Such circuitry employs a Ptat current reference stage and additional stages, which stages contains resistances that are set based on the desired temperature threshold(s) and to set the voltage range of the sensed temperature. These analog voltages are received at temperature threshold detection circuitry, which produces digital signal(s) indicating whether the sensed temperature has passed the temperature threshold(s). The digital signal(s) are then provided to digital circuitry in the IMD, where they can be stored as a function of time for later review, or used to immediately to control IMD operation.

Abstract: A flow sensor assembly includes a housing that defines an inlet port, an outlet port, a main channel and a bypass channel. An inlet flow channel fluidly connects the inlet port of the flow sensor assembly to the main channel and an outlet flow channel fluidly connects the main channel to the outlet port. A bypass feeder input channel fluidly connects the main channel to the bypass channel and a bypass feeder output channel fluidly connect the bypass channel to the main channel. In some instances, at least 40 percent of an input pressure differential applied between the inlet port and the outlet port of the flow sensor assembly drops across the inlet flow channel and the outlet flow channel collectively. A sensor is exposed to a fluid in the bypass channel and senses a measure related to a flow rate of the fluid flowing through the bypass channel.
