  • Patent number: 9474892
    Abstract: A method and system for improving the effectiveness of cardioversion and defibrillation through the ability to reduce transthoracic impedance. A method and system of decreasing transthoracic impedance that allows standardized pressure to be applied directly over desired defibrillator patches. This system reduces transthoracic impedance by increasing effective pressure on desired patches through use of a manual depressor device which incorporates a deformable patient body interface and mechanical and or electronic mechanisms to provide qualitative and or quantitative feedback on the force being applied to said patches. By depressing the device over desired external adhesive electrode patches until an audio and or visual signal indicates sufficient applied pressure, increased patch to skin contact is achieved to decrease the effective transthoracic impedance of a patient upon delivery of a defibrillation shock.

  • Patent number: 9320884
    Abstract: A method and system improves the effectiveness of cardioversion or defibrillation through the ability to switch shock vectors and to reduce transthoracic impedance. An external multiple patch system comprises at least two options for a shocking vector once external patches are applied and adhered to desired locations on a patient's body. A manual switching mechanism in the system provides the ability to direct current from a defibrillator to either of two or more adhesive electrode patches. A method and system of decreasing transthoracic impedance comprises wrapping material around a patient's body to apply pressure to adhered patches, which further reduces transthoracic impedance by increasing effective pressure on the patches through use of pressure-focusing mechanisms located between a patch and a strap.

  • Publication number: 20150217121
    Abstract: A method and system for an improved wearable defibrillator specifically optimized for patient comfort and compliance. The system is capable of sensing information about the patient, determining whether the patient is experiencing a life-threatening arrhythmia, and if so, deliver life-saving defibrillation. The system is specifically designed, constructed, and configured to allow for minimal weight on the shoulders and its associated lumbar spine compression when standing and minimal pressure on the abdomen or thorax when supine in order to increase patient comfort and compliance. This configuration and design can be implemented in several forms including but not limited to the material(s) used, the placement of various components, the durability of the components, the operative or communicative connection between various components, the efficiency and/or accuracy of the various components in performing their functions, and/or the maintenance procedure.

  • Publication number: 20140163663
    Abstract: A method and system for improving the effectiveness of cardioversion or defibrillation through the ability to switch shock vectors and to reduce transthoracic impedance. A “shock vector” or “shocking vector” is herein defined as the path and direction which electrical current follows in traversing a patient body cavity between two external adhesive electrode patches. An external multiple patch system comprises at least two options for a shocking vector once external patches are applied and adhered to desired locations on a patient's body. A manual switching mechanism in the system provides the ability to direct current from a defibrillator to either of two or more specified shocking vectors. A method and system of decreasing transthoracic impedance comprises wrapping material around a patient's body to apply pressure to adhered patches.
