Abstract
A method of making an electrosurgical patient electrode includes the steps of initially providing an electrode body having a recess defined therein with an electrically conductive bottom surface, and then casting a quantity of uncured hydrogel material into the recess. The gel material is sufficient in volume to fill the recess and is subsequently cured in situ.
Claims16
A method of making an electrosurgical patient electrode, comprising the steps of:
- providing a flexible support layer of electrically non-conductive material,
- mounting a layer of flexible, electrically conductive material on said support layer to produce a flexible backing layer having an electrically conductive surface on one side thereof,
- mounting a flexible, apertured layer of electrically non-conductive material on said one side of said flexible backing layer, said apertured layer defining an aperture through which at least a portion of said electrically conductive surface is exposed, said backing layer and said apertured layer thereby defining a recess having an electrically conductive bottom surface,
- pouring a quantity of uncured, substantially fluid, electrically conductive, hydrogel material into said recess so as to fill said recess, and
- curing said gel material.
A method of making a medical electrode including a cured gel material for providing electrical contact with the skin of a patient, comprising the steps of:
- providing a flexible backing layer having an electrically conductive surface on at least a portion of one side thereof,
- mounting a flexible, electrically non-conductive layer on said one side of said backing layer, said non-conductive layer defining an opening such that at least a portion of said conductive surface is exposed through said opening, and a recess, having an electrically conductive bottom surface, is defined,
- pouring a quantity of an uncured, electrically conductive gel material into said recess, and
- curing said gel material.
A method of making a disposable electrode of the type which includes a quantity of electrically conductive, cured gel material for contacting the skin of a patient, comprising:
- providing an electrode body having a recess defined therein with an electrically conductive bottom surface, said bottom surface being in direct electrical communication with a connection tab extending from said electrode body,
- casting a quantity of uncured hydrogel material into said recess, said hydrogel material being sufficient in volume to fill said recess, and
- curing said hydrogel material.
