  • Patent number: 11040205
    Abstract: In some examples, a processor of a system evaluates a therapy program based on a score determined based on a volume of tissue expected to be activated (“VTA”) by therapy delivery according to the therapy program. The score may be determined using a three-dimensional (3D) grid comprising a plurality of voxels that are each assigned a value. The processor may register the VTA with the 3D grid and determine the score for the therapy program based on the values assigned to voxels with which the VTA overlaps. One or more therapy programs for electrical stimulation therapy (e.g., deep brain stimulation) may be selected based on the scores determined based on the 3D grid.

  • Patent number: 11013429
    Abstract: A method to identify feature points associated with the heart valve movement, heart contraction or cardiac hemodynamics is revealed. The mechanocardiography (MCG) is a technology that makes use of vibrational waveforms acquired using at least one gravity sensor attached on one of the four heart valve auscultation sites on the body surface. The data of the electrocardiography (ECG) is recorded simultaneously with the MCG The feature points are identified by comparing P, R and T points of synchronized ECG with the MCG spectrum. By the time sequences and amplitudes of the feature points, the method provides additional clinical information of cardiac cycle abnormalities for diagnosis.

  • Patent number: 10946208
    Abstract: A wearable cardioverter defibrillator (WCD) system includes a processor, a memory, a wireless communication module (DWCM), and an NFC tag that stores information for how an accessing device may access the DWCM wirelessly. An accessing device such as a defibrillator configurator with an NFC reader may read the NFC tag of the WCD system, if it has adequate permission to do so. Upon so reading, the accessing device will know how to address the DWCM wirelessly, and thus install or update configuration data, software updates, or request memory downloads from operations. The use of the NFC tag requires close proximity, which hampers both inadvertently programming the wrong WCD system, plus a WCD system being attacked maliciously.
