    摘要： An implantable medical device includes an optical hemodynamic sensor comprising at least one optical emitter and at least one detector. In some examples, the at least one optical emitter may be optically coupled to at least one light transmission member that extends from a housing of the medical device. In addition, in some examples, the at least one detector may be optically coupled to at least one light transmission member that extends from the housing of the medical device. In other examples, an optical emitter and/or detector of a hemodynamic sensor may be carried by an elongated member that extends from a housing of the IMD. The elongated member may electrically couple the optical emitter and/or detector to a controller or other components within the IMD housing.

    摘要： A medical device identifies a hemodynamically unstable arrhythmia based upon optical hemodynamic sensor signals. The optical hemodynamic sensor includes a light source for transmitting light corresponding to first and second wavelengths through a blood perfused tissue of a patient and a light detector for generating optical signals corresponding to an intensity of the detected light at the first and second wavelengths. At a low motion period for the patient, optical signals are obtained from the optical hemodynamic sensor and are analyzed to determine a baseline motion level for the patient. Subsequent signals obtained from the optical hemodynamic sensor are compared to the baseline motion levels, with only those signals corresponding to periods where motion does not exceed the baseline level of motion being further analyzed to determine if they are consistent with a hemodynamically unstable arrhythmia.

    摘要： A medical device system and associated method are used for monitoring tissue oxygenation. An optical sensor produces a signal corresponding to tissue light attenuation. A processor receives the optical sensor signal and computes a first measure of light attenuation at a first light wavelength and a second measure of light attenuation at a second light wavelength. In one embodiment, noise cancellation circuitry receives the first measure and the second measure and generates a guessed ratio of the first and second measures. Using the first measure, the second measure and the guessed ratio, the noise cancellation circuitry provides a peak output power when the guessed ratio corresponds to an actual ratio of the first and second measures.

    摘要： An implantable medical device (IMD) includes an electrode that forms a first snap-fit attachment area and an insulator that forms a through-hole, a second snap-fit attachment area and a third snap-fit attachment area. The second snap-fit attachment area mates with the first snap-fit attachment area of the electrode. The IMD further includes a body including an elongated conductive housing and a feedthrough wire extending therefrom. The body forms a fourth snap-fit attachment area on one end that mates with the third snap-fit attachment area of the insulator such that the feedthrough wire extends through the through-hole of the insulator. The housing encloses at least one of a battery, a sensor, and an electronic circuit. The insulator functions to electrically isolate the electrode from the housing of the body.
