Triangular or Crescent Shaped Defibrillation Electrode

Abstract

A defibrillation electrode for application to the front of the chest of a patient, the electrode comprising a metallic layer, a conductive liquid-containing layer in contact with the metallic layer and configured to contact the skin of the patient, an adhesive layer surrounding the conductive liquid-containing layer and having a layer of adhesive configured to adhere the electrode to the patient, a release layer configured to be removed from the electrode prior to application to the patient, the release layer being in contact with the adhesive and the conductive liquid-containing layer prior to removal, wherein the electrode has a lateral perimeter at or laterally outside of the adhesive layer, and wherein the lateral perimeter is generally triangular.

1 . A method of applying a defibrillation electrode to the chest of a patient, comprising:
 removing from a storage package a defibrillation electrode that comprises
 a metallic layer, 
 a conductive liquid-containing layer in contact with the metallic layer and configured to contact the skin of the patient, 
 an adhesive layer surrounding the conductive liquid-containing layer and having a layer of adhesive configured to adhere the electrode to the patient, 
 a release layer configured to be removed from the electrode prior to application to the patient, the release layer being in contact with the adhesive and the conductive liquid-containing layer prior to removal, 
 wherein the electrode has a lateral perimeter at or laterally outside of the adhesive layer, and 
 wherein the lateral perimeter is generally crescent shaped with three corners; and 
   positioning the defibrillation electrode adjacent to the breast of the patient with none of the three corners riding up on the breast.   
   
   
       2 . The method of  claim 1  wherein the lateral perimeters of the adhesive and release layers are also generally crescent shaped. 
   
   
       3 . The method of  claim 2  further comprising three or more ECG monitoring electrodes, with one monitoring electrode located adjacent each of the three corners of the crescent shaped perimeter. 
   
   
       4 . The method of  claim 3  further comprising an electrical conductor electrically connected to the metallic layer and extending from the electrode at a location approximately midway along one edge of the crescent shaped perimeter. 
   
   
       5 . The method electrode of  claim 1  wherein the defibrillation electrode is packaged with a second defibrillation electrode configured to be placed on a second location on the patient, and the second electrode has a lateral perimeter that is other than generally crescent shaped. 
   
   
       6 . The method of  claim 5  wherein the second electrode has a generally square perimeter. 
   
   
       7 . A defibrillation electrode for application to the front of the chest of a patient, the electrode comprising
 a metallic layer,   a conductive liquid-containing layer in contact with the metallic layer and configured to contact the skin of the patient,   an adhesive layer surrounding the conductive liquid-containing layer and having a layer of adhesive configured to adhere the electrode to the patient,   a release layer configured to be removed from the electrode prior to application to the patient, the release layer being in contact with the adhesive and the conductive liquid-containing layer prior to removal,   wherein the electrode has a lateral perimeter at or laterally outside of the adhesive layer, and   wherein the lateral perimeter is generally crescent shaped.   
   
   
       8 . The electrode of  claim 7  wherein the defibrillation electrode is packaged with a second defibrillation electrode configured to be placed on a second location on the patient, and the second electrode has a lateral perimeter that is other than generally crescent shaped.
