摘要： Aspects of the instant disclosure relate to an electrophysiological catheter system for performing diagnostics and therapies within a cardiac muscle; more specifically, to a deformable body, at a distal end of a catheter, that deforms in response to a force being exerted upon a tip of the catheter. The deformation of the deformable body being measured by a measurement device, and the deformation associated with both a magnitude and vector of the force exerted upon the catheter tip.

摘要： An apparatus and method for performing cardiac ablations employs a catheter comprising an anchoring device and an ablating device to perform the ablations to electrically isolate the pulmonary veins and left atrium from surrounding atrial tissue. The anchor can comprise a balloon-type device, a stent-like device, a strut-like device, a spring-strut-like device, an umbrella-like device, a mushroom-like device, or other device that allows the catheter to maintain a position with respect to target tissue. The ablator can comprise a balloon ablator, an umbrella ablator, a pinwheel ablator, an umbrella ablator incorporating a cinch mechanism, a mushroom balloon ablator and a segmented balloon or pinwheel ablator. The anchor and ablator can also comprise a combination mushroom balloon anchor section and mushroom balloon ablator section. The anchor and ablator can include electrodes for measuring a conductance therebetween when in deployed position, so as to determine the effectiveness of the ablation.

摘要： A system and method for supplying microwave energy to tissue for microwave therapy includes an electrosurgical generator having an output for coupling to a surgical instrument. The electrosurgical generator includes a microwave energy source and a controller for controlling the operation of the electrosurgical generator. The surgical instrument, coupled to the electrosurgical generator, includes a microwave antenna for delivering microwave energy from the microwave energy source. The controller of the electrosurgical generator is operable for causing the electrosurgical generator to apply at least two pulses of microwave energy.

摘要： A method and system for atrial fibrillation ablations utilizing a fluoroscopy and/or medical image(s) based cardiac mapping system adapted for balloon based catheters including cryoballoon catheter. The method and system incorporates overlaying two or more sets of images on top of each other where the transparency between the images can be adjusted as an aid in the optimal placement of the balloon based catheters. Further, tags and markers are also placed on fluoroscopic and/or other medical images indicative of where the tissue that has been ablated. The method and system also comprises the ability to monitor esophageal temperature, and to activate alarms and/or energy delivery interrupt based on pre-determined esophageal temperature parameters.

摘要： System, devices and methods are presented that integrate stretchable or flexible circuitry, including arrays of active devices for enhanced sensing, diagnostic, and therapeutic capabilities. The invention enables conformal sensing contact with tissues of interest, such as the inner wall of a lumen, a the brain, or the surface of the heart. Such direct, conformal contact increases accuracy of measurement and delivery of therapy. Further, the invention enables the incorporation of both sensing and therapeutic devices on the same substrate allowing for faster treatment of diseased tissue and fewer devices to perform the same procedure.

摘要： Described embodiments include apparatus that includes a catheter and a tip electrode, at a distal end of the catheter, shaped to define a plurality of fluid apertures. A structure, within the tip electrode, is configured such that fluid passed distally through a lumen of the catheter flows in a longitudinal direction through a space between the structure and an inner surface of the tip electrode, prior to exiting through the fluid apertures. Other embodiments are also described.

摘要： This invention provides a device for mapping and ablating the renal nerves distributed on renal artery, having a guide catheter, a mapping-ablation catheter, a handle and a connector. The guide catheter has at least one lumen and a distal end with adjustable curvature. The mapping-ablation catheter is housed in one of the lumens of the guide catheter and its distal end has one or more electrodes and one or more detecting devices. The distal end of the mapping-ablation catheter is curved, rotatable, and can be extended out of or retracted into the guide catheter. The handle connects the guide catheter and mapping-ablation catheter, and has one or more controlling components for controlling the movement of the guide catheter and mapping-ablation catheter. The connector is designed to supply energy to the electrodes.
