摘要： A self-limiting electrosurgical return electrode for use with electrosurgical procedures is disclosed. The return electrode includes a conductive element and pads disposed on opposing sides of the conductive element. The conductive element, optionally in combination with the pads, is configured to limit the density of electrical current that passes from a patient to the return electrode. The conductive element and the pads can cooperate to define two separate working surfaces on opposing sides of the return electrode. The return electrode can also be safely used with patients of substantially any size and without requiring adjustments to the power settings of an electrosurgical generator.

摘要： A return electrode detection and monitoring system and method thereof are provided. The system and method of the present disclosure provide for a combined universal recognition feature, that is to identify whether a return or neutral electrode coupled to an electrosurgical generator is a capacitive electrode or a split or non-split (solid) resistive electrode. Furthermore, the system and method will monitor both capacitive and resistive return electrodes when the electrosurgical generator is operating in the 4 Mhz range to notify an operator when the return electrode is not coupled enough which would effect power delivery to the patient and hence effect on the targeted tissue.

摘要： A method and a measurement apparatus are provided for determining the transition impedance between two electrode parts of a subdivided neutral electrode used in high-frequency surgery. These makes it possible for the purely capacitive component of the transition impedance to be measured. For this purpose a resonant-frequency shift is measured, which occurs when a basic resonant circuit is expanded to an expanded resonant circuit by incorporating the two electrode parts into it in parallel. In particular, in order to determine the basic resonant frequency of the basic resonant circuit and/or the sample resonant frequency of the expanded resonant circuit, the phase shift between current and voltage is measured and the frequency is adjusted until current and voltage are in phase.

摘要： A self-limiting electrosurgical electrode for use with electrosurgery and various other surgical procedures. The electrode can include a pad and a conductive element that collectively has an effective bulk impedance equal to or greater than about 4,000 &OHgr;·cm. The effective bulk impedance of the electrode arises from resistive components, capacitive components, inductive components, or combinations thereof of both the pad and the conductive element. Through the selection of the impedance characteristics for the electrode materials, and through tailoring of electrode geometries, the electrode of the present invention is self-regulating and self-limiting as to current density and temperature rise so as to prevent patient trauma. Additionally, the selection of materials and electrode geometries can prevent the creation of pressure sore or decubitus ulcers on a patient resting upon the electrode. Further, alternate configurations of the electrosurgical electrode can heat and/or cool a patient during the performance of a surgical procedure.

摘要： A tissue ablation system and method are provided. The system includes a catheter including a distal electrode tip having at least one tip electrode, at least one return electrode positionable independently of the tip electrode, and a voltage generator circuit electrically connected to the tip electrode and to the return electrode. The tip electrode and the return electrode include a dielectric or other non-conductive surface layer. The voltage generator circuit applies a voltage differential across the tip electrode and the return electrode such that the tip electrode and the return electrode are given opposite polarity. Tissue located between the tip electrode and the return electrode acts as a capacitive dielectric medium in which an electric field is present and is not dependent on current flow between the tip electrode and the return electrode, and the electric field induces electroporation of tissue cells in a vicinity of the distal electrode tip.

摘要： The present disclosure provides electroporation systems, methods of controlling electroporation systems to limit electroporation arcs through intracardiac catheters, and catheters for electroporation systems. One method of controlling an electroporation system including a direct current (DC) energy source, a return electrode connected to the DC energy source, and a catheter connected to the DC energy source is disclosed. The catheter has a at least one catheter electrode. The method includes positioning the return electrode near a target location within a body and positioning the catheter electrode adjacent the target location within the body. A system impedance is determined with the return electrode positioned near the target location and the catheter electrode positioned within the body. The system impedance is adjusted to a target impedance to limit arcing from the catheter electrode.

摘要： An electric heating pad for warming a patient. The electric heating pad may be a heated underbody support, heated mattress or heated mattress overlay. An embodiment of the heating pad includes a flexible sheet-like heating element including an upper edge, a lower edge, and at least two side edges. The heating pad may also include a shell covering the heating element and comprising at least two sheets of flexible material (e.g., two sheets may be one sheet folded over to form at least two sheets). The two sheets of flexible material may be coupled together about the edges of the heating element by a weld. The material of the two sheets may include urethane. In some embodiments, a catalyst to accelerate hydrogen peroxide decomposition is coated on or impregnated into an element within the shell, or on the interior surface of the shell.
