  • Patent number: 11504537
    Abstract: Systems and methods for monitoring chronic over-pacing (COP) to the heart are discussed herein. In an embodiment, a system includes a receiver circuit to receive information about pacing rates of a plurality of paced heart beats, and a pacing analyzer circuit to generate a pacing rate distribution using pacing rates of the plurality of the paced heart beats. The pacing rate distribution includes a pacing rate histogram. The pacing analyzer circuit may recognize a morphological pattern from the pacing rate distribution, and detect a COP indication using the extracted feature. A programmer circuit adjusts one or more therapy parameters in response to the detected. COP indication.

  • Patent number: 11077297
    Abstract: Implantable leads of a cardiac stimulus system are disclosed, as well as methods for implanting leads of a cardiac stimulus system. The lead may be comprised of a proximal portion having a coupler for coupling to an implantable pulse generator, an intermediate portion comprising a plurality of electrodes disposed thereon, and a distal portion. The intermediate portion may have a first diameter and the distal portion may have a second diameter. The distal portion may also have an attachment feature for attaching to a lead pulling tool for delivery to an ITV and an intercostal vein. Methods may include pulling a lead from a first position to a second position within the vasculature, exiting the vasculature at the second location, and attaching a portion of the lead that exits the vasculature to an electrode or implantable device for use with the lead.

  • Patent number: 10980570
    Abstract: Implantation of a cardiac stimulus system using the intercostal veins. Superior, intercostal, and inferior access methods are discussed and disclosed. Superior access may be performed by entering the brachiocephalic vein from a jugular, subclavian, or other vein, and then accessing the internal thoracic vein, traversing a portion of the internal thoracic vein and then accessing an intercostal vein therefrom. Inferior access may be accomplished inferior to the lower rib margin via the superior epigastric vein, advancing superiorly into the internal thoracic vein and then accessing an intercostal vein therefrom. Intercostal access may include creating an opening in an intercostal space between two ribs and advancing a needle using ultrasound guidance to enter the intercostal vein directly.

  • Patent number: 10864378
    Abstract: Regulating cardiac activity may include pacing the patient's heart at a starting pacing rate and instigating an intrinsic heart beat search algorithm that includes pacing at a reduced rate for a period of time and capturing electrical signals representative of cardiac electrical activity while pacing at the reduced rate in order to determine a presence or absence of intrinsic heart beats. If intrinsic heart beats are not detected, the heart may be paced at a further reduced rate for a period of time. If intrinsic beats are detected, the heart may be paced again at the starting pacing rate. This may continue until intrinsic heart beats are detected or until a lower search rate limit is reached. Diagnostic data may be collected at each stage and transmitted to a display device for analysis by a physician or the like.
