Abstract: An electrosurgical stapling instrument includes an end effector capable of applying bipolar RF energy into tissue. The end effector has a first pole electrode and a second pole electrode for forming an RF contact circuit with tissue. At least one of the electrodes may have a dielectric coating thereon to create a RF circuit with tissue. The dielectric coating can cover one of the electrodes to create a capacitive coupling circuit with tissue, or can have at least one open passageway extending through the dielectric coating to enable tissue contact with the electrode and the passage of RF energy therethrough. The dielectric coating on the electrode can be masked to create passageways through the dielectric, or the dielectric coating can be locally removed with a variety of techniques to form passageways. The dielectric coating may provide a barrier to prevent shorting between the dielectrically coated electrode and a conductive fastener embedded within tissue. Alternately, a cartridge coating can be used to reduce an electric surface sheet charge on the cartridge thermoplastic that can occur during the application of RF energy to tissue.

Abstract: Methods and devices are provided for handling data in an implantable restriction system. In general, the methods and devices allow collection, analysis, storage, and transmission of pressure measurements. Pressure measurement data can be compressed before storing it. Additionally, not all pressure data need be recorded or retained, such as data substantially equaling a resting or nominal pressure of an implantable restriction device indicative of little to no pressure variation and data indicative of isolated, non-recurring events. Any pressure measurement data that is recorded can be transmitted to an external device using power telemetrically provided by the external device.

Abstract: Query electrodes are provided for monitoring the electrical impedance of tissue as it is treated with electrosurgical energy. In one embodiment, based on a predicted model of tissue impedance and a number of initial impedance readings, the impedance at which tissue treatment is completed is predicted. More particularly, a minimum impedance level is measured and a function of the minimum impedance is used to determine impedance at which coagulation is completed. A control device is provided for bringing the output of the generator within an optimum range based on a system load curve. In one embodiment the impedance monitoring device is used in conjunction with a bipolar electrosurgical instrument. Preferably, the instrument comprises electrically opposite therapeutic electrodes, each located on one or more tissue engaging surfaces for engaging tissue to be treated, and electrically opposite query electrodes, located on one or more tissue engaging surfaces. The therapeutic electrodes provide therapeutic energy to the tissue while the query electrodes provide a lower voltage electrical sensing energy for the purpose of measuring tissue impedance at various stages, e.g. before, during, or after tissue treatment.
