摘要： A variety of improved ablation catheters and methods for using such catheters are described. In one embodiment, the catheter includes a plurality of longitudinally spaced split electrode bands that are provided near the distal end of the catheter to monitor electrophysiological signals in the patient. The electrode bands each include a plurality of electrically isolated electrode segments. The number of electrode segments in each band may be widely varied, as may the number of electrode bands. In another embodiment, the catheter has a transducer that is movable longitudinally relative to the flexible tubular member. In one embodiment, the transducer is carried at the distal end of the transmission line and the transmission line is slideably received within the flexible tubular member such that the transducer can be positioned longitudinally relative to the electrode bands. In still another embodiment, the electrodes are ion implanted on the flexible tubular member. The described catheter is introduced into a patient's body such that a distal portion of the catheter is positioned in a vessel or chamber of an organ such as the heart. The electrodes are used to monitor electrophysiological signals and an appropriate ablation position is identified based at least in part on the monitored electrophysiological signals. The transducer is then positioned at the identified ablation position and electromagnetic energy is applied to a transducer through a transmission line to cause ablation of tissue in a region adjacent the identified ablation position.

摘要： A stent crimping apparatus for crimping a deformable radioactive stent onto a deployment device which includes a first jaw member defining a shielded first compression surface, and an opposed, second jaw member defining a shielded second compression surface oriented opposite the first compression surface. The first and second compression surfaces are adapted to collectively form an elongated guide bore formed for axial receipt of the deformable stent and the deployment device therein. To protect against exposure to the radioactive stent, a shield assembly is provided defining an opening into a bore therein which is formed and dimensioned for longitudinal receipt of the deformable stent in an uncrimped condition. A shield assembly defines an opening into the bore, and cooperates with the first and second jaw members to substantially prevent radioactive particles emitted by the radioactive stent from passing out of the crimping apparatus. An operating mechanism is operatively coupled to the first and second jaw members for selective movement between a loading condition and a crimping condition. In the loading condition, the uncrimped stent and the deployment device may be inserted through the opening and into the bore. In the crimping condition, the deformable stent is radially compressed onto the deployment device between the first and second compression surfaces.

摘要： A scanning system for a film recorder utilizes multiple digital-to-analog converters (DACs) to produce a linear output for a vertical deflection circuit which drives a vertical yoke circuit for controlling a CRT beam in a film recorder. The system contains a coarse DAC, a fine DAC, and a delta DAC which provides a signal representing the analog change from line to line. A summing circuit, a difference amplifier, a A/D converter, and a calibration sequence controlled by a DSP create a table to effectively increase the resolution and linearity of the deflection output signal.
