  • Color coded header bore identification using multiple images and lens arrangement
    Patent number: 9724527
    Abstract: An implantable pulse generator includes a device housing containing pulse generator circuitry and a header connected to the device housing. The header includes a core assembly defining first and second lead bore cavities sized for receiving terminal pins of leads, first and second labels, and an outer layer. The first label is printed onto a surface of the core assembly proximate the first lead bore cavity and includes a first color. The second label is printed onto the surface of the core assembly proximate the second lead bore cavity and includes a second color different from the first color. The outer layer is overmolded over the core assembly so as to encapsulate the first and second labels and to allow access to the first and second lead bore cavities.

  • SPATIAL CONFIGURATION OF A MOTION SENSOR IN AN IMPLANTABLE MEDICAL DEVICE
    Publication number: 20170056666
    Abstract: Implantable devices having motion sensors. In some examples the a configuration is generated for the implantable device to use the motion sensor in an energy preserving mode in which one or more axis of detection of the motion sensor is disabled or ignored. In some examples the motion sensor outputs along multiple axes are analyzed to determine which axes best correspond to certain patient parameters including patient motion/activity and/or cardiac contractility. In other examples the output of the motion sensor is observed across patient movements or postures to develop conversion parameters to determine a patient standard frame of reference relative to outputs of the motion sensor of an implanted device.

    Abstract: Systems, devices, and methods for adjusting functionality of an implantable medical device based on posture are disclosed. In some instances, a method for operating a leadless cardiac pacemaker implanted into a patient, where the patient has two or more predefined behavioral states, may include detecting a change in the behavioral state of the patient, and in response, changing a sampling rate of a sensor signal generated by a sensor of the leadless cardiac pacemaker. In some embodiments, the method may further include using the sampled sensor signal to determine an updated pacing rate of the leadless cardiac pacemaker and providing pacing to the patient at the updated pacing rate.
