摘要： An electrophysiology energy treatment device for treating tissues within a patient's body with electrical energy comprises an elongate catheter tube having a distal end insertable into the patient's body. An electrode is within the catheter tube adjacent the distal end and locatable within the patient's body, and an electrolyte fluid flows within the catheter tube for electrically connecting the electrode to the tissues to be treated within the patient's body. A method of treating tissues within a patient's body with electrical energy is also provided. The method comprises the steps of: providing an energy treatment device having an electrode and a distal tip, the electrode being located within the patient's body offset proximally of the distal tip; placing the distal tip within the patient's body adjacent the tissues to be treated with electrical energy; energizing the electrode with electrical energy; and electrically connecting the electrode to the tissues to be treated with an electrolyte fluid flowing from the electrode to the tissues for treating the tissues with electrical energy.

摘要： A method of making a return pad for an electrosurgical system comprises the following steps. A first step includes die cutting an electrically conductive foil on a backing using a rotary press to create a foil blank. A second step includes peeling the conductive foil from around the blank, and leaving the blank on its backing. A third step includes layering electrically conductive gel together with the die cut foil to form a layered sheet. A fourth step includes blanking the return pad from the layered sheet using a rotary die. The rotary die has cutting edges and a die packing material adjacent to at least a portion of the edges. The die packing material compresses the gel prior to cutting. The compression is preferably sufficient to cause elastic deformation in the gel so that the gel retracts after being cut. The retraction of the gel leaves a border around the edge of the pad. The border region helps prevent the possibility of the gel coming into electrical contact with an unintended object. One of the advantages of the method of manufacturing disclosed herein is that a continuous rotary process can be used to manufacture electrosurgical return pads. The continuous nature of the process increases the efficiency of the manufacturing operation. The apparatus for using the method is also disclosed.

摘要： A medical electrode and skin preparation device is adapted to be secured to the skin and is designed to prepare the skin by penetration of the epidermal layer of the skin in contact with the electrical conductor of the electrode after the electrode is secured in place on the skin. The electrode includes abrading member associated with electrical conductor capable of transmitting biopotential events for recording, with the electrical conductor retained by a collar and adhesive-coated pad securing the electrode to the skin of the patient. The abrading member in contact with the skin is movable relative to the skin of the patient and collar by an applicator gun to penetrate the epidermal layer of skin after the electrode is placed on the skin. Uniform skin preparation achieved by the electrode and applicator gun minimizes motion artifacts arising from skin potential variations.

The body has one end of the grounding cable located therein in attachment to the contact plate with the other end of the grounding cable having a terminal plug for insertion in a socket of the electrosurgical generator. As an adjuvant feature, the body has a receptacle engaged with the contact plate and adapted to receive a pin jack on a grounding wire for interconnecting a monitoring patient cable ground circuit of an electrocardiograph machine (E.K.G.) and the electrosurgical patient grounding cable.
