Abstract: A system and method for artifact reduction in thermodilution for cardiac measurement is provided by both respiration artifacts and noise artifacts are reduced. The system and method detects the beginning of a respiration cycle and estimates a respiration artifact which is subtracted from the thermosignal recorded.

Abstract: A method and system for therapeutically treating a selected volume of tissue with a heated liquid. A therapeutic device, such as a catheter, is coupled to a source of liquid is heated to therapeutic temperatures by a heating mechanism. The device imparts thermal energy into the tissue while simultaneously injecting the heated liquid into the tissue. In a preferred embodiment, the device includes at least one electrode for conducting a radio-frequency current through the tissue in conjunction with the infusion of heated saline solution to selectively destroy the tissue.

Abstract: A skin-mounted physiological recording electrode assembly has a foam pad having a front surface having a central recess and mounted to the skin, and a rear surface. A pad passage extends from the central recess to the rear surface. An electrode in the pad passage has a sensing end in the central recess and a connector end to which a clip attaches. The clip attaches to a lead wire connecting to a monitoring device. At least one deformation gauge is coupled to the rear surface of the foam pad, and may be a strain gauge, a bending sensor, or a combination of both. The electrode assembly may be used in a patient monitoring system having an electrode signal processor, sensor signal processors, a multiplexer, an A-to-D convertor, and a microprocessor programmed with an adaptive noise canceling algorithm.
