fig1 - 3 illustrate the medical electrode assembly 10 according to the present invention . the assembly includes dual layers , 12 and 14 , that can be provided as patches , pads , or the like and be of substantially any size desired . the assembly 10 can include more than two layers ; however , in its preferred embodiment , the assembly 10 of the present invention consists of a pair of opposed continuous layers . a free exposed end 16 of carbon fiber , steel fiber , copper fiber or any other type of electrically - conductive stimulation lead wire 18 is attached to the assembly 10 by being secured and sandwiched between the dual layers , 12 and 14 . both of the dual layers , 12 and 14 , are transparent or translucent to visible light , ultraviolet light , and / or infrared light . for example , with respect to the preferred embodiment , the dual layers , 12 and 14 , are substantially clear and a person can visual see directly through the dual layers , 12 and 14 , to objects located on the other side of the dual layers , 12 and 14 . preferably , each of the dual layers , 12 and 14 , are continuously transparent or translucent throughout their entire body so as not to block , absorb , reflect , or prevent substantially any transmission of light through any part of the assembly 10 and therefore , enable maximum passage of light to the patient &# 39 ; s skin 20 lying directly underneath the assembly 10 . the only exception is the relatively small and thin lead wire 18 which may not be transparent and may absorb and / or reflect rays of light . otherwise , the entire assembly 10 is transparent or translucent to light and permits light rays “ r ” emitted by a phototherapy device , or light source , 22 to shine through the layers , 12 and 14 , onto the skin 20 of the patient . see fig4 and 5 . preferably , the dual layers , 12 and 14 , include a lower flexible layer 12 intended to engage the skin 20 of the patient and an upper flexible layer 14 that faces outward of the skin 20 toward the phototherapy , or light source , device 22 . the flexibility of the layers 12 and 14 enable the assembly 10 to conform to the contour of the skin 20 on which it is attached . flexibility is particularly important for relatively large assemblies having a relatively large surface area . alternatively , the layers , 12 and 14 , can be substantially rigid if the assembly is relatively small and has only a small surface area . as an example , the lower layer 12 can be a sticky , tacky , or self - adhesive gel - like substance . such a gel layer 12 can be electrically - conductive such that it electrically couples the lead wire 18 to the skin 20 . in addition , the gel layer 12 can have an exterior relative - tacky surface enabling the gel layer 12 to be removably self - adhered directly to the skin 22 of the patient . the upper face 24 of the gel layer 12 can also be tacky for purposes of self - adhering the lead wire 18 thereto and for adhering the upper layer 14 thereto . alternatively , separate adhesive layers can be used . the upper flexible layer 14 can be made of the same gel material as the lower flexible layer 12 . if desired , the upper gel layer 14 can made of a conductive gel material , or more preferably , a non - conductive gel material . its surfaces can be tacky to enable it to form a strong bond with the lower gel layer 12 and lead wire 18 . its upper face 26 can also be tacky to enable the separate phototherapy , or light source , device 22 to be removably adhered thereto . see fig5 . alternatively , the upper layer 14 may not have a self - adherent property . preferably , the assembly 10 is provided as a disposable medical electrode assembly . for instance , as best illustrated in fig1 , the assembly 10 can initially be provided on a release sheet 28 that can be peeled away from the underside of the assembly 10 . also , the lead wire 18 can have a proximal free end forming a connection tip 30 . in this manner , a lead wire of an electrical stimulation device 32 can be connected to tip 30 . however , when discarding a used assembly 10 , the assembly can be disconnected and only the short portion 34 of the lead wire need be discarded . a method of treatment according to the present invention includes adhering lower layer 12 to the skin 20 of the patient . the proximal end of the lead wire 18 can be electrically connected to the electrical stimulation device 32 for electrically stimulating the patient via the medical electrode assembly 10 . as an example , electrotherapy is typically given for about a period of 8 to 12 minutes depending upon the purpose of the application . simultaneously with the electrotherapy treatment , a phototherapy light source 22 can be used to provide phototherapy to the skin 22 of the patient , including the skin located directly underneath the medical electrode assembly . phototherapy treatment typically is longer in duration then electrotherapy treatment . thus , there may be periods of time where only phototherapy treatment or only electrotherapy treatment is applied . however , the use of the medical electrode assembly 10 enables the treatments to be applied simultaneously or sequentially without any disconnection or re - connection of the electrode assembly to the patient . according to one contemplated embodiment , the phototherapy light source 22 comprises a small lightweight light emitting diode ( led ) cluster that can be adhered directly to the upper tacky face 26 of the upper layer 14 of the assembly 10 . thus a phototherapy treatment and an electrotherapy treatment can be given simultaneously to substantially the same region of the body . alternatively , the light source can be a large bank of lights not supported on the assembly or connected to the assembly . the type of light rays used during phototherapy depends upon the purpose of the application . visible or optical light having a wavelength of about 400 nm to 700 nm could be used , and the assembly 10 could permit such electromagnetic radiation to pass through the layers , 12 and 14 , of the assembly . alternatively , ultraviolet rays could be used , including uv - a , uv - b , or uv - c rays . this would correspond to electromagnetic radiation of a wavelength within the range of about 10 to 400 nm . still further , infrared rays could be used , including near or far infrared . this would correspond to electromagnetic radiation of a wavelength within the range of about 700 nm to 1 , 000 , 000 nm . according to one contemplated embodiment the medical electrode assembly would permit passage of light rays having a wavelength of between 280 nm to 50 , 000 nm , or alternatively , between 400 nm and 1000 nm . while preferred electrodes and methods of treatment have been described in detail , various modifications , alterations , and changes may be made without departing from the spirit and scope of the electrode assembly and method according to the present invention as defined in the appended claims .
a method for combining the effective modalities of electrotherapy and phototherapy is provided . a medical electrode assembly is substantially transparent or translucent to visible , infrared and / or ultraviolet light so that light rays emitted by a phototherapy device can shine through and pass transversely across every layer of the medical electrode assembly to impinge upon the skin of the patient to which the assembly is attached . this includes an area of skin located directly underneath the medical electrode assembly and thereby enables the combination therapy to be achieved
