Abstract: An ablation catheter is provided with an elongated member or shaft (110) and a plurality of helically-shaped cutting wires (104) atached to the shaft to form a cutting basket (150). Each of the cutting wires has a section formed as a circumferentially subscribing arc (105) and together the wires present a circumferential cutting area of an essentially cylindrical configuration. Each of the wires (104) comprises a first curved or straight section (123) extending from the distal end of shaft (110) to a discontinuity such as a corner or kink (125). Obstructing matter on the inner surface of a vessel cavity, such as a blood vessel or the like, is separated from the surface as the catheter is moved through the vessel. The catheter may be inserted in a vessel in a standard fashion using a wire guide (102) which extends through a longitudinal passageway in the shaft and a hub (103) interconnecting the basket wire. The shaft and basket together may be contained in an outer sheath to facilitate insertion. The outer sheath with the basket in a collapsed state in the outer sheath may be readily moved past an obstruction, and the sheath withdrawn to allow the basket to expand and come in contact with the interior surface of the vessel cavity. The proximal ends of the cutting wires extend from the shaft through a vibratory transducer, and the distal ends are connected together by a hub. Electrical current is applied to electrical terminals connected to the cutting wires at the proximal end of the shaft to heat the wires to facilitate separating obstructing matter from a vessel surface. Futhermore, the vibration transducer vibrates the cutting wires to further aid in separating plaque and obstructions from soft tissue such as the intima layer of the wall of a blood vessel.

Abstract: A liquid-crystal display device includes a first liquid crystal layer 16 having a dichroic dye contained therein, and a second liquid-crystal layer 18 having light-scattering properties. The first and the second liquid-crystal layers are separate and superposed one above the other between a pair of glass plates 12, 14. A color filter 32 is provided on one (14) of the plates. The threshold voltage of the first liquid-crystal layer 16 is, for example, lower than the threshold voltage of the second liquid-crystal layer 18 (V₁ < V₂). Accordingly, when the voltage applied to the liquid crystal is lower than the threshold voltage V₁ of the first liquid-crystal layer 16, the light is absorbed by the dichroic dye to produce a black spot. When the voltage is higher than the threshold voltage V₁ of the first liquid-crystal layer 16 and lower than the threshold voltage V₂ of the second liquid-crystal layer 18, the second liquid-crystal layer becomes white and cloudy thereby producing a white spot on the display. When the voltage is higher than both threshold voltages the light passes through both first and second liquid-crystal layers and is reflected directly off the color filter 32. Color can therefore be displayed additively rather than substractively.

Abstract: At thinning, under the condition that a second multiplexer is switched to output an output of a first adder and a third multiplexer is switched to output an output of a second adder, a first multiplexer is alternatively switched at every line. A delay circuit memorizes an added result of a one-line preceding input signal and a two-line preceding input signal, and the second adder outputs at every two lines an added result of image data of a present line, a one-line preceding line and a two-line preceding line. At interpolation, under the condition that the second multiplexer is switched to output the output of the delay circuit, the first multiplexer is alternatively switched to output one of the input signal and the output of the second multiplexer, and the second multiplexer is alternatively switched to output one of the output of the second adder and the output of the delay circuit. Thus, the delay circuit outputs at every two lines an added result of the one-line preceding input signal and the two-line preceding input signal, which leads to size reduction of a perpendicular thinning/interpolation circuit for an image signal.

Abstract: An implantable medical interventional device delivers electrical therapies to the heart of the implant patient to treat pathological tachycardia. A first sensor of the device generates a signal indicative of the patient's ECG, and a second sensor in the form of an activity sensor such as an accelerometer generates a signal representative of the current status of physical exercise by the patient. An evaluation system of the device establishes heart rate criteria for recognizing pathological tachycardias, to be applied against the ECG signal to recognize pathological tachycardia and distinguish it from physiological tachycardia experienced by the patient. A control system of the device modifies the criteria according to the nature of the exercise status signal, to enhance recognition and distinction. In an embodiment, the criteria of heart rate at the boundary between physiological and pathological tachycardia for the particular implant patient is modified by shifting it to a different rate. The boundary rate is shifted to a higher rate when the exercise status signal indicates a change from patient rest to patient exercise, and to a lower rate when that signal indicates a change from patient exercise to patient rest. Bipolar floating electrodes sense atrial ECG status, and solely atrial defibrillation is applied when ventricular tachycardia is found attributable to primary atrial fibrillation. Such a situation may be determined by measuring the R-R interval of the beats to detect irregularity. The modification of the tachycardia recognition criteria is disabled when primary atrial fibrillation is detected.
