  • System for improving neurostimulation compliance
    Patent number: 10946194
    Abstract: Nerve stimulation systems and methods are disclosed for providing improved compliance of a patient to a therapy regimen. Patient compliance is assessed and notification or treatment events can be scheduled, rescheduled or otherwise adjusted based upon patient compliance or non-compliance according to compliance rules and parameters of a treatment compliance module. Both compliance and non-compliance may lead to adjustment of the treatment regimen, scheduled treatment events, and notifications. Gamification of the treatment regimen allows users to obtain points that may be used to receive virtual awards, status awards, or monetary compensation of various forms. Monitoring of usage and compliance can be managed both locally and remotely from the user. Stimulation treatment, compliance monitoring, and gamification is disclosed for treatments using external or implanted stimulators, or the combination.

  • High efficiency blood pump
    Patent number: 10905807
    Abstract: Blood pumps discussed herein may be suitable for use as a ventricular assist device (VAD) or the like. The blood pumps cause minimal blood damage, are energy efficient, and can be powered by implanted batteries for extended periods of time. Further, these pumps are also beneficial because they may improve the quality of life of a patient with a VAD by reducing restrictions on the patient's lifestyle. The blood pumps can provide radial and axial stability to a rotating impeller that is driven by a separate rotor. Both radial and axial stability can be provided, at least in part, by one or more permanent magnetic couplings between the rotor and the impeller and/or one or more permanent magnetic bearings between the pump housing and the impeller.

  • Scar assessment
    Patent number: 10898093
    Abstract: Apparatus for assessing scarring of cardiac tissue, consisting of a probe and a processor. The probe has one or more electrodes, which are configured to contact the tissue at a plurality of positions and to sense respective voltages in the tissue at the positions. The processor receives the respective voltages, and computes a triangular mesh that is representative of a surface of the tissue and that consists of multiple triangles having vertices corresponding to the positions contacted by the one or more electrodes. The processor calculates respective scar areas within the triangles by comparing the respective voltages sensed at the positions corresponding to the vertices to a predefined range of the voltages that is associated with scarring, and computes a sum of the respective areas. The processor compares the sum to a total area of the triangles so as to assess a degree of the scarring of the tissue.
