X-ray transparent medical electrodes and lead wires and assemblies thereof
First Claim
1. In an x-ray transparent medical electrode assembly of the type comprising a conductor, means for bridging the conductor to human tissue, and connector means detachably connected to said conductor for connecting said conductor to peripheral equipment, the improvement wherein said conductor comprises a conductive plastic body that includes a stud having a thin metal coating on its outer surface, wherein said connector means comprises a conductive plastic body having an opening extending therethrough for receiving said stud, and wherein said body has surface portions defining marginal portions of said openings that resiliently grip said outer surface of said stud when said connector means is connected to said conductor.

Abstract
A medical electrode assembly which is otherwise free of metal in the area of attachment to a patient so as to be X-ray transparent in such area has a conductive plastic electrode conductor with a silver plated and chlorided coating of a thickness between 0.02 and 0.08 mil. The assembly also has a lead wire formed from an elongate cable having carbon fibers in a low density polymeric jacket and a conductive plastic connector having an opening for gripping a stud formed by the conductive plastic electrode conductor.

14. An x-ray transparent medical electrode assembly comprising:
-
a low-profile, x-ray transparent, plastic electrode conductor made conductive by the inclusion of carbon and having a thin metallic coating on surface portions thereof; an electrolyte engaged with a surface portion of said conductor coated with said thin metallic coating for electrically bridging between said conductor and the skin of a patient; means connected to said conductor for adhering said conductor and said electrolyte to the skin of a patient; an x-ray transparent cable; means connected to one end of said cable for electrical connection to monitoring equipment; and x-ray transparent means for detachably connecting said cable to said conductor comprising a pair of tightly interfitting, conductive plastic members, including a first conductive plastic member which is integrally fixed to said conductor and a second conductive plastic member which is integrally fixed to said lead wire, one of said members having a chlorided silver coating having a thickness before chloriding in the range of 0.02 to 0.08 mils, so that said pair of members when assembled to one another are x-ray transparent and are electrically and mechanically uncompromised by the application thereto of high energy pulses resulting from defibrillation procedures so that reliable traces of heart waves will continue to be obtained after defibrillation pulses have been applied to a patient to whom the electrode assembly is applied. - View Dependent Claims (15, 16, 17, 18, 19)

24. An x-ray transparent medical electrode assembly comprising:
-
a low-profile, x-ray transparent, plastic electrode conductor made conductive by the inclusion of carbon and having a thin metallic coating on surface portions thereof; an electrolyte engaged with a surface portion of said conductor coated with said thin metallic coating for electrically bridging between said conductor and the skin of a patient; means connected to said conductor for adhering said conductor and said electrolyte to the skin of a patient; an x-ray transparent cable; means connected to one end of said cable for electrical connection to monitoring equipment; and x-ray transparent means for detachably connecting said cable to said conductor comprising a pair of tightly interfitting, conductive plastic members, including a first conductive plastic member which is integral with said conductor and a second conductive plastic member which is integral with said lead wire, said first conductive plastic member comprising a stud having a head portion and a neck portion for connection to a snap-fastener connector, said stud further having a base portion below said neck portion, said neck portion having a smaller thickness than said head portion and said base portion, and said second conductive plastic member comprising a thin-walled plate having an opening extending therethrough for receiving said stud, said opening having a larger part for receiving said stud and a smaller part, said plate having relatively movable confronting side walls bounding said smaller part for slideably accepting said neck portion that are mutually spaced apart by a distance less than the thickness of said neck portion and are forced apart upon slideable insertion of said neck portion therebetween so that said side walls firmly grip said neck portion. - View Dependent Claims (25, 26, 27, 28, 29)
