Extended Wear Electrocardiography Patch Using Interlaced Wire Electrodes
First Claim
1. An extended wear electrocardiography patch using interlaced wire electrodes, comprising:
- a flexible backing formed of an elongated strip of stretchable material with a narrow longitudinal midsection evenly tapering inward from a distal end and a proximal end, the elongated strip adherable only to a contact surface defined on each of the ends;
a pair of flexile wires;
a pair of electrodes, one such electrode comprising one of the flexile wires interlaced into the distal end of the elongated strip and continuing back along an axial path through the midsection, another such electrode comprising the other of the flexile wires interlaced into the proximal end of the elongated strip, each of the electrodes further comprising an electrically conductive area only exposed on the contact surface;
a circuit board affixed on the proximal end of the elongated strip, comprising a battery compartment operable to hold a battery for powering an electrocardiography monitor, and an electrical pad operable to electrically couple the electrocardiography monitor with the pair of the electrodes; and
a non-conductive receptacle securely adhered on the one end of the elongated strip opposite the contact surface and formed to removably receive the electrocardiography monitor, the non-conductive receptacle comprising electrode terminals aligned to electrically interface the pair of the flexile wires to the electrocardiography monitor.

Abstract
Physiological monitoring can be provided through a wearable monitor that includes a flexible extended wear electrode patch and a removable reusable monitor recorder. A pair of flexile wires is interlaced or sewn into a flexible backing, serving as electrode signal pickup and electrode circuit traces. The wearable monitor sits centrally on the patient'"'"'s chest along the sternum, which significantly improves the ability to sense cutaneously cardiac electric signals, particularly those generated by the atrium. The electrode patch is shaped to fit comfortably and conformal to the contours of the chest approximately centered on the sternal midline. To counter the dislodgment due to compressional and torsional forces, non-irritating adhesive is provided on the underside, or contact, surface of the electrode patch, but only on the distal and proximal ends. Interlacing the flexile wires into the flexile backing also provides structural support and malleability against compressional, tensile and torsional forces.
