  • Publication number: 20210118572
    Abstract: Two or more electrophysiology characteristics can be graphically represented in a single representation output, for example, by an electroanatomical mapping system. The system can generate or receive multiple electrophysiology maps, one for each of a corresponding number of electrophysiological characteristics. The system can also generate or receive a three-dimensional anatomical model, such as a cardiac surface model, that includes a focal point. The system can identify a display region about the focal point and transform the display region from a three-dimensional surface into a plane. One or more of the electrophysiology maps can be represented by varying the elevation of the plane, e.g., according to value(s) of the represented electrophysiological characteristic(s). One or more additional electrophysiology maps can be represented on the elevation-varied plane, e.g., in color scale, grey scale, or the like.

  • Patent number: 9687667
    Abstract: A magnetic switching device includes an electromagnet adapted to be arranged proximate to an exterior surface of an object having a magnetically-switchable device therein and a control circuit electrically connected to the electromagnet. The electromagnet is constructed to generate a magnetic field of sufficient strength and orientation to engage a switch in the magnetically-switchable device. The invention further includes an electrocautery system, including an electrocautery device, a control circuit electrically connected to the electrocautery device, and an electromagnet electrically connected to the control circuit. The electromagnet is adapted to be arranged proximate to an exterior surface of an object having a magnetically-switchable device therein. Operation of the electrocautery device causes the electromagnet to generate a magnetic field of sufficient strength to engage a switch in the magnetically-switchable device.

  • Patent number: 8611980
    Abstract: The present invention relates to electrocardiography and to electrode arrangements used in electrocardiographic monitoring devices. An EKG patch may include a plurality of individual EKG patches, each comprising a base layer and a plurality of electrodes capable of receiving an electrical signal generated by the myocardium of a human heart. Each of the plurality of the individual EKG patches may be stacked on top of each other such that each electrode in an individual patch aligns and contacts with at least one corresponding electrode in an adjacent EKG patch, thereby allowing a free flow of electricity through the plurality of stacked EKG patches, and such that the bottom-most EKG patch may be contacted with the skin of a patient. A temporary or release adhesive may be placed between each of the plurality of EKG patches such that the bottom-most EKG patch may be peeled away from the stack after each use.
