  • Patent number: 11944461
    Abstract: Systems and methods are described herein for generating representative cardiac information. The representative cardiac information may be based on a plurality of electrode signals monitored, or measured, over a plurality of cardiac cycles or heart beats. The systems and methods may remove unqualified cardiac cycles, remove invalid electrode signals, remove inconsistent cardiac cycles, and removing uncorrelated cardiac cycles, and then generate representative cardiac information based on the remaining cardiac cycles and electrode signals.

  • Publication number: 20230060052
    Abstract: A system for accounting for adverse pacing artifacts may include an electrode apparatus and a computing apparatus. The electrode apparatus may include one or more external electrodes to monitor electrical activity from tissue of a patient. The computing apparatus may include one or more processors and may be operatively coupled to the electrode apparatus. The computing apparatus may be configured to monitor electrical activity from the tissue of the patient using the one or more external electrodes. Such electrical activity may be used to generate one or more cardiac signals of the patient over time. The computing apparatus may detect a pacing artifact in the one or more cardiac signals and determine whether to account for, and account for, the pacing artifact based on a pacing artifact characteristic of the pacing artifact when producing electrical heterogeneity information.

  • Publication number: 20210361219
    Abstract: Electrical activity from tissue of a patient is monitored using a plurality of external electrodes to generate a plurality of electrical signals over time. The plurality of electrical signals are filtered using a first filter having a first frequency range to generate a plurality of first filtered signals. The plurality of electrical signals are filtered using a second filter having a second frequency range different than the first frequency range to generate a plurality of second filtered signals. At least one QRS complex is detected based on the plurality of first filtered signals. A QRS peak of the at least one QRS complex is detected based on the plurality of second filtered signals and the detected at least one QRS complex.

  • Patent number: 9656088
    Abstract: A method and apparatus for determining estimated remaining longevity for an implantable stimulator. A programmer processor is employed to acquire from the implantable stimulator a signal comprising data associated with the power source in the implantable stimulator and a date in which the stimulator was implanted. The programmer processor and the data are used to determine whether a pre-recommended replacement time threshold (pre-RRT) has been attained for replacing the implantable stimulator. The programmer processor is used to select an equation in which to calculate a recommended replacement time (RRT), the equation is selected in response to determining a time period that extends from the date in which the stimulator was implanted until a date in which the pre-RRT is attained.

  • Patent number: 9517032
    Abstract: An implantable sensor module and medical device includes a housing having an inner shell having a thickness extending between an inner wall and an outer wall and an outer layer, wherein the inner shell and the outer layer form a substantially flat portion. A shoulder extends adjacent to a diaphragm to extend the outer layer laterally away from a central medial line extending between edges of the diaphragm. A recess portion is formed between the diaphragm and an inner side of the outer layer, and an over-fill channel is formed by the outer layer extending through the outer layer from an opening formed at the outer wall to an opening formed along the inner side of the outer layer extending along the substantially flat portion.

  • Patent number: 9131858
    Abstract: An implantable sensor module includes a housing having an inner shell and an outer layer formed to extend over and enclose the inner shell to form an outer wall of the housing, the inner shell having a thickness extending between an inner wall of the inner shell and an outer wall of the inner shell, the outer layer having an inner side engaged against the outer wall of the inner shell and having a thickness extending between the inner side and the outer wall of the housing, wherein the inner shell and the outer layer form a substantially flat portion. A flexible diaphragm is formed within the inner shell and extends between a first edge and a second edge, and a shoulder extends adjacent to the first edge to extend the outer layer laterally away from a central medial line extending between the first and second edges of the diaphragm.
