摘要: A method of mapping electrophysiological information, including receiving imaging information for a tissue region; receiving a monophasic action potential signal from the tissue region; assigning a value corresponding to a depolarization segment of the monophasic action potential signal; receiving location information associated with the monophasic action potential signal; and generating an image based on the imaging information, the assigned value, and the location information.

摘要: A method and system for treating ventricular tachycardia (VT) by ablating scarred myocardial tissue containing a reentrant VT circuit. The method generally includes measuring electrical activity at a plurality of sites within a heart, identifying an area of scarred myocardial tissue based at least in part on the electrical activity measurements, and ablating substantially all of the scarred area. The system generally includes a medical device having a distal end, a plurality of electrical conduction sensors coupled to the distal end, and a console in communication with the distal end of the device, the console including a computer with display. The computer may be programmed to identify optimal ablation sites within a target tissue and the location of an isthmus associated with a reentrant VT circuit within a target tissue, the identifications being based at least in part on the measurements of the electrical conduction sensors.

摘要: A device, system, and method for enhancing cooling uniformity and efficiency of cryogenic fluids and providing a treatment element the shape of which can be adjusted for multiple purposes. The device may include a balloon catheter and fluid dispersion element, the fluid dispersion element directing the flow of coolant from a fluid injection element the interior wall of the balloon. The method of changing the shape of the treatment element may include retracting and extending a shaft to which the distal neck of a balloon is coupled, so that the balloon goes from a first shape to a second shape.
