摘要： A system and method for providing digital data communications over a wireless intra-body network is presented. A physical protocol layer is logically defined with an identifier uniquely assigned to a plurality of implantable devices in an intra-body network. Functions are specified within the physical protocol layer to transact data exchange over a wireless interface. A slave implantable device is activated in response to an activation signal transmitted through the wireless interface by a master implantable device. A wireless communications link is established between the slave implantable device and the master implantable device upon matching of the identifier assigned to the slave implantable device. Data is communicated intra-bodily over the communications link.

摘要： A far-field radio frequency telemetry (RF) system for communicating with an implantable medical device includes a diversity antenna system. An antenna control circuit selects one or more antennas of the diversity antenna system for reducing potential data transmission errors associated with nulls encountered by the telemetry system due to environmental reflections of RF electromagnetic waves. In one embodiment, a different active antenna is selected when a transmission failure deemed to be associated with a null is detected. In another embodiment, a new antenna is selected on a regular basis to reduce the probability of encountering a null. In another embodiment, the telemetry system includes multiple processing paths each associated with one antenna of the diversity antenna system, and a different processing path is selected when the transmission failure deemed to be associated with a null is detected.

摘要： An implantable cardiac device is configured and programmed to collect blood pressure waveforms from one or more implantable pressure sensors. Techniques are described for extracting features and reducing noise in the pressure waveforms by averaging waveforms which are aligned with a detected cardiac cycle. Noise can also be reduced by gating and calibration functions performed in accordance with other sensor data.

摘要： Methods and systems provide for anchoring implantable medical device inside a bodily vessel. An anchoring structure can include a stent-like structure to which the IMD is attached. The stent-like structure is positioned at a desired location in the bodily vessel. The stent-like structure can be repositioned based on a measurement from the IMD. The IMD can include outwardly extending fins over which tissue can fibrose to affix the IMD to a wall of the bodily vessel. The stent-like structure can be made of a bio-absorbable material. The IMD can be attached to a stent-like structure by leads, by being lodged in a recessed diaphragm, by being embedded in mesh of the stent-like structure, or other methods. The stent-like structure can be balloon deployable to allow for controlled positioning and anchoring. The anchoring structure can include a vena cava filter.

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 receive 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”), which includes a main body; and a remote sensor system operable to measure an absolute physiologic parameter value within a patient's body. The system further comprises an external device, which can be operable to obtain an ambient condition value outside the patient's body that can affect the absolute physiologic parameter value, and communicate the ambient condition value to the remote sensor system. In accordance with one embodiment, the remote sensor system then can be further operable to receive the ambient condition value and calculate a relative physiologic parameter value from the ambient condition value and the absolute physiologic parameter value.
