  • Patent number: 9731108
    Abstract: The present application relates to an electrode pad comprising at least one electrode with an electrode terminal. A contact member such as a hydrogel is disposed on said electrode terminal and covered by a retainer mesh. The electrode terminal may be, for example, a silver electrode disposed on a flexible foil, and the contact member may be disposed in the aperture of a backing layer. The retainer mesh is designed to allow for an electrical contact of the contact member to an object such as the body of a person while at the same time mechanically retaining the contact member. Moreover, the electrode pad may comprise an array of several electrodes disposed on a carrier, said carrier having a slit separating at least two neighboring electrodes.

  • Patent number: 9717433
    Abstract: Physiological monitoring can be provided through a lightweight wearable monitor that includes two components, a flexible extended wear electrode patch and a reusable monitor recorder that removably snaps into a receptacle on the electrode patch. The wearable monitor sits centrally on the patient's chest along the sternum oriented top-to-bottom. The placement of the wearable monitor in a location at the sternal midline, with its unique narrow “hourglass”-like shape, significantly improves the ability of the wearable monitor to cutaneously sense cardiac electrical potential signals, particularly the P-wave and the QRS interval signals indicating ventricular activity in the ECG waveforms. In particular, the ECG electrodes on the electrode patch are tailored to be positioned axially along the midline of the sternum for capturing action potential propagation in an orientation that corresponds to the aVF lead used in a conventional 12-lead ECG that is used to sense positive or upright P-waves.

  • Patent number: 9610016
    Abstract: This multipurpose, modular system provides diagnostic-quality, wireless, multichannel monitoring in diverse settings, including interventional procedures guided by X-ray and MRI, with variable electromagnetic interference (EMI) and eliminates the need for multiple detachments/reattachments of patient cables when the patient is moved from one room/procedure to another. The system includes: 1) multiple filterbanks (filtering procedures) for recording both diagnostic-quality (broad-band) signals in the absence of EMI and narrow-band signals in the presence of EMI, with subsequent reconstruction of diagnostic-quality signals from the narrow-band signals; 2) filtering of EMI, using a priori and adaptive criteria about differences between the EMI and physiological signals' characteristics; 3) filtering of the magneto-hydrodynamic effect, using physiological measurements at different distances from the magnet (i.e.
