摘要： Medical devices using fluid or cooling fluids having one or more bimaterial valves positioned at each point of flow control to control the flow of a fluid in response to temperature changes. In particular, devices for ablating tissue having multiple ablation elements or cells include one or more bimaterial valves positioned within or near the ablation cells. The bimaterial valves respond to temperature changes by adjusting the flow rate of a fluid through the valve.

摘要： A device for ablating cardiac tissue includes a plurality of ablation elements substantially aligned along a common axis and adjustable between first and second predetermined positions. In the first predetermined position, the plurality of ablation elements form a curved contact surface. In the second predetermined position, the plurality of ablation elements form a substantially straight insertion configuration. At least one hinge (27) may connect adjacent ones of the plurality of ablation elements (26). Each of the plurality of ablation elements may be located within a housing (29), which may have at least a portion of a hinge integrally formed therewith to connect adjacent ablation elements. Alternatively, a strand of superelastic material (38), such as a Nitinol wire, may interconnect ablation elements. The superelastic material may bias the plurality of ablation elements into at least one of the first and second predetermined positions.

摘要： An ablating device having one or more piezoelectric micropumps for delivering a flowable material to a target tissue. The device may be coupled to a controller configured to monitor tissue temperature, ablation element temperature, transducer impedance and/or degree of contact between the ablation elements and a tissue and to adjust the flow rate of the flowable material in response to changes in temperature, transducer impedance and/or degree of contact between the ablation elements and the tissue. Methods of ablating tissue using devices of the present invention are also described.

摘要： A method of manufacturing an ultrasound transducer (2) is provided. The ultrasound transducer (2) is activated and the activity across the transducer is measured to determine whether the activity at any area does not meet an acceptance criteria. The transducer is then modified so that the area meets the acceptance criteria. The transducer may be modified with a laser (43) which removes material from the area which does not meet the accceptance criteria.
