    摘要： A tissue-ablation method and apparatus are disclosed. The apparatus includes a plurality of RF ablation electrodes, and a plurality of sensor elements, each movable from retracted to deployed positions in a tissue to be ablated. A control device in the apparatus is operatively connected to the electrodes for supplying an RF power to the electrodes, to produce tissue ablation that advances from individual-electrode ablation regions to fill a combined-electrode ablation volume. The control device is operatively connected to the sensor elements for determining the extent of ablation in the regions of the sensor elements. The supply of RF power to the electrodes can thus be regulated to control the level and extent of tissue ablation throughout the combined-electrode volume. The electrodes are preferably hollow-needle electrodes through which liquid can be infused into the tissue, also under the control of the control unit, to modulate and optimize tissue ablation.

    摘要： An arm position control device for use in an industrial robot which comprises: a support body; a rotary arm rotatably mounted on the support body for rotation towed one of clockwise and counterclockwise deviation zones from a home position within a permissible angular extent; a home position sensor fixedly attached to the support body to identify home position of the rotary arm; a limit sensor fixedly secured to the support body with a predetermined angular spacing from the home position sensor to detect movement of the rotary arm beyond the permissible angular extent; a sensor actuator rotatable with the rotary arm as a unit for keeping the home position sensor interrupted when the rotary arm lies in the clockwise deviation zone, for making the home position sensor released when the rotary arm lies in the counterclockwise deviation zone and for bringing the limit sensor into a released condition as the rotary arm is out of the permissible angular extent; and an arm actuator operatively coupled to the rotary arm for causing it to rotate counterclockwise when the home position sensor remains interrupted for causing the rotary arm to rotate clockwise when the home position sensor is kept released and for having the rotary arm move into the permissible angular extent when the limit sensor is in a disabled condition.

    摘要： A system for removing an in-place intravascular device such as a catheter or guidewire from a patient's body lumen such as from a coronary artery and advancing a catheter or other similar device through the vascular system until its distal end is located at a desired location within the vascular system. The system includes an exchange catheter, which may be a dilatation catheter, having a flexible strand forming a loop at the distal end of the catheter which is adapted to be disposed about the guidewire or catheter which is in-place within the patient. The loop is tightened about the elongated intraluminal in-place device to be removed so that the catheter can be advanced over the in-place device until the distal end of the catheter is at a desired location within the patient's vasculature. The catheter may be used to perform a diagnostic or therapeutic procedure such as an angioplasty or a replacement device may be advanced through an inner lumen and out the distal end of the catheter.
