Abstract: A method and apparatus for delivery of energy by an electro-surgical instrument to a surgical site is disclosed. The apparatus delivers power to electrodes of an electro-surgical instrument during an operation performed at a surgical site. The apparatus includes a processor and a plurality of power delivery channels. The processor signals the onset of an impedance interval and a heating interval. The processor determines a target value of a control parameter to be delivered to a corresponding one of the electrodes. The plurality of power delivery channels are each coupled to the processor and to a corresponding electrode. Each of the power delivery channels responsive to signaling from the processor transitions between the impedance interval and the heating interval. Each of the power delivery channels measures, during the impedance interval, an impedance associated with a delivery of energy to the surgical site by a corresponding electrode. Each of the power delivery channels, during the heating interval, minimizes a difference between a measured value of a control parameter and the target value of the control parameter determined by the processor, to deliver the energy to the surgical site. In an alternate embodiment of the invention a method for controlling power delivery in an electro-surgical instrument is disclosed. In an alternate embodiment of the invention a method for controlling power delivery in an electro-surgical instrument is disclosed. In an alternate embodiment of the invention a method for controlling power delivery in an electro-surgical instrument is disclosed.

Abstract: An ablation apparatus for ablating an inner layer in an organ or lumen of a body, or any desired thin layer, includes an expandable member made of a material with a porous exterior surface. An electrolytic solution, housed in an interior of the expandable member, releases electrolytic solution through the porous exterior surface. A conforming member, which can be an open cell foam material, has an RF conductive surface, and a back side in a surrounding relationship to an exterior surface of the expandable member. Further, the conforming member includes non-zone areas that have a first porosity rate for delivering electrolytic solution to the inner layer. The conforming member also includes a zone for housing each RF electrode and electrolytic solution. Zones have a second porosity rate that is less than the first porosity rate, thus permitting electrolytic solution to pass through the non-zone areas at a faster rate than in the zones. The zones provide an area where electrolytic solution is heated to a higher temperature, due to the differences in porosity with the non-zones. With the combination of the electrode and the heated electrolytic solution in each zone, a larger electrode is created, and there is a more effective, and even application of both RF and thermal energy to the tissue site, such as the endometrium.

Abstract: A working end of a surgical instrument that carries first and second jaws for delivering energy to tissue. In a preferred embodiment, at least one jaw of the working end defines a tissue-engagement plane that contacts the targeted tissue. The cross-section of the engagement plane reveals that it defines a surface conductive portion that overlies a variably resistive matrix of a temperature-sensitive resistive material or a pressure-sensitive resistive material. An interior of the jaw carries a conductive material or electrode that is coupled to an Rf source and controller. In an exemplary embodiment, the variably resistive matrix can comprise a positive temperature coefficient (PTC) material, such as a ceramic, that is engineered to exhibit a dramatically increasing resistance (i.e., several orders of magnitude) above a specific temperature of the material.
