  • Patent number: 10849500
    Abstract: Various embodiments are directed toward a system and method for determining an orientation of an implantable medical device (“IMD”) and automatically adjusting a subcutaneous electrocardiogram (“ECG”) signal based on the determined orientation. The method can further include tagging generated SECG signals so as to identify whether a SECG signal had been generated from an implantable monitoring device with its first electrode being superior or inferior relative to its second electrode. Further embodiments can include automatically adjusting the orientation of the generated SECG signals to match that of a preferred orientation.

  • Patent number: 10799707
    Abstract: In an electrostimulator which applies electrical stimulation to patient tissue, measurements of lead impedance (tissue resistance), battery status, and like matters are used to format and/or truncate the ranges of programmable therapeutic output settings available for selection by a clinician. The clinician can therefore better tell whether chosen settings can actually be successfully implemented, and/or whether they may have adverse effects on device lifespan or patient safety.

  • Patent number: 9687659
    Abstract: An implantable medical device including a data communication interface connected to a pulse generator. The pulse generator generates and delivers forward current pulses and reverse current pulses, wherein a polarity of the reverse current pulses is opposite to the polarity of the forward current pulses. Generates pulses representing binary digits, wherein a first kind of digits (1 or 0) is represented by a current pulse, and a second kind of digit respective of the other type of binary digits (0 or 1) is represented by a pause between current pulses. The data communication interface together with the pulse generator deliver current pulses with strictly alternating polarity such that every other current pulse is a reverse current pulse of opposite polarity compared to an immediately preceding forward current pulse. Thus, every string of current pulse is both, charge balancing and information encoding.
