摘要： An embodiment of the invention provides a tissue biopsy and treatment apparatus that comprises an elongated delivery device that is positionable in tissue and includes a lumen. A sensor array having a plurality of resilient members is deployable from the elongated delivery device. At least one of the plurality of resilient members is positionable in the elongated delivery device in a compacted state and deployable with curvature into tissue from the elongated delivery device in a deployed state. At least one of the plurality of resilient members includes at least one of a sensor, a tissue piercing distal end or a lumen. The sensor array has a geometric configuration adapted to volumetrically sample tissue at a tissue site to differentiate or identify tissue at the target tissue site. At least one energy delivery device is coupled to one of the sensor array, at least one of the plurality of resilient members or the elongated delivery device.

摘要： The apparatus and method of the current invention relate to electrosurgical work involving the forming of cuts in and coagulation of body tissue of a patient. The apparatus and method of the invention overcome disadvantages common with conventional dipolar and monopolar apparatus. In one aspect the invention provides a cutting tool or instrument with at least one cutting or coagulation tip and the tool is adapted to operate as both a power supply electrode to supply power to the tip and as a return electrode to allow impedance feedback signals to be received by a control means thereby eliminating the need for a separate second electrode and taking the patient out of the circuit received by a control means. According to a second aspect the feedback information is stored, processed and analysed in relation to pregrogrammed and previous actual feedback to allow alteration to the power supply to the tip to create optimum cutting and/or coagulating conditions.

摘要： Systems and methods well suited for use in catheter based tissue ablation systems employ thermocouples (80) for temperature sensing at an energy emitter site (30). The sensed temperature is used to control the energy output from the energy source to maintain tissue temperature within desired parameters. The systems combine accuracy with compact, low profile construction.

摘要： This invention is a system and associated method to ablate body tissue using multiple emitters (30) of ablating energy. The system and method convey ablating energy individually to each emitter (30) in a sequence of power pulses. The system and method periodically sense the temperature of each emitter (30) and compare the sensed temperatures to a desired temperature established for all emitters (30) to generate a signal individually for each emitter (30) based upon the comparison. The system and method individually vary the power pulse to each emitter (30) based upon the signal for that emitter to maintain the temperatures of all emitters essentially at the desired temperature during tissue ablation.

摘要： Cardiac catheterization is carried out by memorizing a designation of a contact state between an electrode of the probe and the heart wall as one of an in-contact state and an out-of-contact state, and making a series of determinations of an impedance phase angle of an electrical current passing through the electrode and another electrode, identifying maximum and minimum phase angles in the series, and defining a binary classifier adaptively as midway between the extremes. A test value is compared to the classifier as adjusted by a hysteresis factor, and a change in the contact state is reported when the test value exceeds or falls below the adjusted classifier.
