摘要： An implantable medical device (IMD) is adapted for detecting acoustic chest sounds. The IMD includes a pulse generator having a compartment, the compartment defining an isolated cavity bounded by a back wall. A diaphragm is disposed over and encloses the cavity. An acoustic sensor adapted to sense chest sounds and generate a signal is disposed between the diaphragm and the back wall. The IMD also includes a control circuit disposed within the pulse generator. The circuit is operatively coupled to the acoustic sensor and is adapted to analyze the signal.

摘要： One embodiment of the present invention relates to a system for deriving physiologic measurement values that are relative to ambient conditions. In one embodiment, the system comprises an implantable medical device ("IMD") and an external monitor. The IMD is adapted to determine an absolute physiologic parameter value within a patient's body, and communicate the absolute physiologic parameter value outside the patient's body, for example, to the external monitor. Further, the external monitor is adapted to receive the absolute physiologic parameter from the IMD and obtain an ambient condition value outside the body that can affect the absolute physiologic parameter value. The external monitor then calculates a relative physiologic parameter value from the ambient condition value and the absolute physiologic parameter value.

摘要： A system (100) and method (320, 340) for providing digital data communications over a wireless intra-body network (117) is presented. A physical protocol layer (292) is logically defined with an identifier uniquely assigned to a plurality of implantable devices (103, 116a-d) in an intra-body network (117). Functions are specified within the physical protocol layer (292) to transact data exchange (200) over a wireless interface (283). A slave implantable device (202) is activated in response to an activation signal transmitted through the wireless interface (283) by a master implantable device (201). A wireless communications link is established between the slave implantable device (202) and the master implantable device (201) upon matching of the identifier assigned to the slave implantable device (202). Data is communicated intra-bodily (131) over the communications link.
