摘要:
Communication power in a medical device system is managed by providing power from a power supply to a communication circuit in a sensing device according to a first communication wake up mode set for a first time period and according to a second communication wake up mode set for a second time period. The second communication wake-up mode is established by a second device.

This disclosure relates to implantable medical devices (IMDs); in particular, to medical electrical leads having an integrated sensor disposed in a hermetic package and said sensor package accommodates a torque coil and an elongated cable conductor extending therethrough. The integrated sensor can include a pressure sensor, an accelerometer, and the like. The coil and the cable can couple to pacing and sensing electrode coupled to the lead distal to the sensor package. The sensor package is compact, substantially circular in cross section and robust, in that the overall design promote mechanical stability.

An implantable medical system includes a first die substrate with a first outer surface. The system also includes a second die substrate with a second outer surface. Furthermore, the system includes a medical device with a first portion that is mounted to the first die substrate and a second portion that is mounted to the second die substrate. The first and second die substrates are fixed to each other and substantially hermetically sealed to each other. Also, the medical device is substantially encapsulated between the first and second die substrates. The first portion is electrically connected to the second portion. Moreover, the first and second outer surfaces of the first and second die substrates are directly exposed to a biological material.

A medical device for monitoring a patient condition includes a sensor capable of being advanced transvascularly to be positioned along a volume of tissue, the sensor including a first combination of a light source and a light detector to emit light into a volume of tissue and to detect light scattered by the volume of tissue and to generate a first output signal corresponding to an intensity of the detected light. A control module is coupled to the light source to control the light source to emit light at least four spaced-apart light wavelengths, and a monitoring module is coupled to the light detector to receive the output signal and compute a measure of tissue oxygenation using the light detector output signal.
