摘要： Apparatus, having an insertion tube that is configured to be inserted into a body cavity. The apparatus also includes a distal tip connected to the insertion tube, the 5 distal tip having an external surface and a cavity formed in the external surface, the cavity being surrounded by a region of the external surface having a curvature. The apparatus further includes a microelectrode configured to fit into the cavity so that a surface of the microelectrode 10 is contoured, located and oriented to conform with the curvature of the region.

摘要： The subject of this disclosure is devices, systems, and uses thereof to treat a plurality of patients for paroxysmal atrial fibrillation. The solution can include delivering a multi-electrode radiofrequency balloon catheter and a multi-electrode diagnostic catheter to one or more targeted pulmonary veins; ablating tissue of the one or more targeted pulmonary veins using the multi-electrode radiofrequency balloon catheter; diagnosing the one or more targeted pulmonary veins using the multi-electrode diagnostic catheter; and achieving at least one of a predetermined clinical effectiveness and acute effectiveness of the method or use based on use of the multi-electrode radiofrequency balloon catheter and the multi-electrode diagnostic catheter in the isolation of the one or more targeted pulmonary veins.

摘要： Cardiac catheterization is conducted using a probe having a balloon assembly, in which a spring has a resting axially elongated configuration and a torsed, axially shortened configuration. A balloon is twisted about the spring and mechanically linked to the spring. A flexible sheath is disposed about the spring within the balloon, the sheath and the wall of the balloon defining a chamber to contain a fluid flowing therein and thereout of the balloon.

摘要： A catheter adapted for greater mapping resolution and location precision has a basket-shaped, high density electrode assembly for large-area mapping, and an integrated distal tip providing an array of ultra-high density microelectrodes for acute focal mapping. The basket-shaped electrode assembly 18 has a plurality of electrode-carrying spines and the distal tip has a nonmetallic, electrically insulating substrate body with indentations in which microelectrodes are positioned in a manner that the outer surface is generally flush with the outer surface of the substrate body to present a generally smooth, atraumatic distal tip profile.

摘要： A catheter probe comprises an insertion tube, and a distal end with a distal electrode, a force sensor to detect force on the distal electrode, and an irrigated electrode mounted on a coupling member of the force sensor, which has a tubular form surrounding a central space occupied by components, including force sensing coils. A fluid diverter that passes fluid to the proximal irrigated electrode is configured as an insert or an integrated projection of the coupling member, which configuration minimizes its space demand within the coupling member. Thus, the diameter of the distal end need not be increased. The fluid diverter has a proximal entry opening and a distal exit opening connected by a fluid passage with at least a radial branch and at least an axial branch. The irrigated electrode is mounted over the distal exit opening to receive fluid from the fluid passage.

摘要： A medical probe includes an insertion tube having a distal end configured for insertion into a body of a patient and containing a lumen for conveying an irrigation fluid and an electrical conductor for conveying electrical energy. A conductive cap is attached to the distal end of the insertion tube and coupled electrically to the electrical conductor. The conductive cap has an outer surface perforated by multiple apertures and defines an inner cavity in fluid communication with the lumen of the insertion tube so as to permit the irrigation fluid from the lumen to flow out of the cap through the apertures. A plurality of temperature sensors are mounted within the conductive cap in thermal communication with the outer surface and are thermally insulated from the irrigation fluid in the inner cavity.

摘要： A catheter having a catheter shaft that has a more uniform construction throughout its length and is able to provide more than one deflection curvature. The catheter shaft includes a flexible outer tubular member, and a less flexible inner tubular member extending through the outer tubular member in a proximal section of the catheter shaft, wherein the inner tubular member is afforded longitudinal movement relative to the outer tubular member. The catheter also includes at least one puller wire extending through the inner tubular member to deflect a distal deflection section of the catheter shaft, wherein longitudinal movement of the inner tubular member relative to the outer tubular member enables an operator to select and set a deflection curvature of the distal deflection section.

摘要： Devices and methods are disclosed for providing and using an ablation catheter. The catheter may include an expandable member having a plurality of electrodes, where each electrode is in association with at least one contact sensor and at least one light emitting element. Light is emitted in response to the contact of the contact sensor with the tissue to be ablated. A light sensor disposed centrally to the catheter gathers light emitted from the light emitting elements and sends a signal to a system controller for display.
