摘要： In general, the disclosure is directed toward an implantable medical device that includes a plurality of sensor modules that are implanted within a patient. The sensor modules may cooperate with each other to coordinate the timing for performance of one or more sensor actions across the modules when making a measurement. Example measurements include tissue perfusion measurements, oxygen sensing measurements, sonomicrometry measurements, and pressure measurements. The coordination of the sensor modules may be controlled by a signal that is transmitted from a host controller to the sensor modules via a bus. In some examples, the bus may have two wires that transmit both timing information and data information to the sensor modules. The signal may be a signal that is substantially periodic, such as a pulsed signal. In additional examples, the signal may supply operating power and timing information to the sensor modules.

摘要： An implantable medical device includes a hermetically sealed housing and a first light emitting diode (LED) enclosed within the housing configured to detect light corresponding to a selected light wavelength. A conductive element extends from the LED for carrying a current signal corresponding to the light detected by the LED, the intensity of the detected light being correlated to a change in a physiological condition in a body fluid volume or a tissue volume proximate the LED.

摘要： A system and method for obtaining a virtual physiologic voltage signal between a first predetermined point in a second selected point in the body is disclosed. At least three electrodes are used to measure two voltage signals S1 and S2 in a body. In one embodiment, the signal S1 is measured between a first electrode and a common electrode, and the signal S2 is measured between a second electrode and the common electrode. A selected point within the body may be chosen to define a pair of virtual electrodes existing between this selected point and the common electrode. An approximation of the voltage signal S as could be measured between electrodes positioned at these virtual electrode locations may be derived as a function of S1, S2, and theta, wherein theta is the angle between the directional vector U1 for the signal S1 and the directional vector U for the signal S. According to the inventive system and method, the signal value for S is also dependent on the distances between the electrode pairs, on the angle beta between directional vectors U1 and U2, and on the distance between the virtual electrodes. The current invention may be utilized with electrodes that are positioned either externally on the surface of, or implanted within, a body. According to one aspect of the invention, a user may employ a user interface to select the values of theta, beta, and the electrode spacings. Alternatively, ones of these parameters may be predetermined by the system. In another embodiment, the system could derive the signal S over a predetermined range of values for the angle theta. The system may then select the angle of theta resulting in the derived signal S that exhibits a desired waveform morphology.

摘要： The invention discloses a subcutaneous electrode array or SEA for use in medical devices. The arrangement provides an enhanced capability for detecting and gathering electrical cardiac signals via the array of relatively closely spaced subcutaneous electrodes. Further, switching circuits, signal processors and memory to process electric cardiac signals are implemented to enable a leadless orientation-insensitive SEA scheme for receiving the electrical signal from the heart. The SEA is distributed over the perimeter of the implanted medical device and includes a non-conductive surround shroud of biocompatible material. The surround shroud is placed around the periphery of the case of the implanted medical device. Various configurations of recesses, each of which contain individual electrodes, are implemented to provide an enhanced signal to noise ratio for improved signal quality.

摘要： A circuit for determining lead impedance during the time a pacing or other stimulating electrical pulse is being delivered measures current and voltage simultaneously to check for open circuits or short circuits based on different thresholds. The detection of a bad lead can force a double pulse to be delivered in real time in a unipolar configuration. Switching from bipolar to unipolar configuration based on detecting a bad bipolar circuit can be supported.
