    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”), an external computing device, and a backend computing system. The IMD determines an absolute physiologic parameter value within a patient's body, and communicates the absolute physiologic parameter value outside the patient's body, for example, to the external computing device. Further, the external computing device receives the absolute physiologic parameter from the IMD and communicates it to the backend computing system. The backend computing system receives the absolute physiologic parameter value and obtains an ambient condition value outside the body that can affect the absolute physiologic parameter value. The backend computing system then calculates a relative physiologic parameter value from the ambient condition value and the absolute physiologic parameter value, and in some embodiments, stores the relative physiologic parameter value in a storage location, such as a memory or database.

    摘要: An apparatus and method is presented for an implanted sound sensor wirelessly communicating with an implantable medical device, or with an external monitoring device. The second sensor may be located inside a blood vessel anchored by an expandable stent like device, and may be drug coated. The sound sensor may be a solid-state microphone having a unidirectional characteristic and may be aimed at a selected portion of the heart, lung, or other location. There may be a network of sound sensors forming a local area network with the implantable medical device. The information from the sound sensor may be analyzed, filtered, transformed, compared to a standard and stored in the implantable device, or it may be passed on to an external location. The results of the analysis may be use to initiate a closed-loop treatment by the implantable medical device, such as cardiac pacing or defibrillation.

    摘要: A system and method for waking up an implantable medical device (“IMD”) from a sleep state in which power consumption by the IMD is essentially zero. The IMD may be adapted to perform one or more designated measurement and/or therapeutic functions. In one embodiment, the IMD includes a wake-up sensor that is adapted to sense the presence or absence of a wake-up field generated by another IMD or an external device. The wake-up field may, in some embodiments, be an electromagnetic field, a magnetic field, or a physiologically sub-threshold excitation current (i.e., E-field). Upon sensing by the wake-up sensor of the wake-up field, other components of the IMD, which may include a controller, a sensing and/or therapy module, and/or a communications module, are awakened to perform one or more designated functions.

    摘要: A method and system for enabling secure communications between an implantable medical device (IMD) and an external device (ED) over a telemetry channel. A telemetry interlock may be implemented which limits any communications between the ED and the IMD over the telemetry channel, where the telemetry interlock is released when the ED transmits an enable command to the IMD via a short-range communications channel requiring physical proximity to the IMD. As either an alternative or addition to the telemetry interlock, a data communications session between the IMD and ED over the telemetry channel may be allowed to occur only after the IMD and ED have been cryptographically authenticated to one other.

    摘要: An implantable medical device system includes an implanted device communicating with an external device via telemetry. The implanted device and the external device each have a telemetry module connected to an antenna system to support a radio-frequency (RF) telemetry link. The antenna system of the external device has a manually or automatically controllable directionality. The controllable directionality is achieved, for example, by using two or more directional antennas, one non-directional antenna and one or more directional antennas, or an electronically steerable phased-array directional antenna.
