摘要： An ablation catheter system for drug refractory symptomatic paroxysmal atrial fibrillation (PAF). The system can include an elongated body; an electrode assembly comprising a shell configured with an inner chamber and a wall defining a proximal portion and a distal portion, the wall of the distal portion having at least one aperture; and a micro-element extending through the inner chamber between the proximal portion and the distal portion, the micro-element having a distal end received in the at least one aperture, the distal end being at least coextensive with an outer surface of the wall. The system is configured to achieve acute procedural PVI success for all patients of a predetermined patient population suffering from PAF.

摘要： A method of constructing an inflatable electrode assembly configured for irrigation, comprises: providing a flex circuit having a substrate with a pre-formed aperture, the substrate constructed of a material having a greater heat resistance or a first melting temperature; providing a balloon member with a membrane, the membrane constructed of a material having a lesser heat resistance or a second melting temperature lower than the first melting temperature of the substrate; affixing the substrate to the membrane wherein a surrounding portion of the substrate around the pre-formed aperture masks a surrounding portion of the membrane so as to expose a target portion of the membrane; and applying heat to the target portion of the membrane through the pre-formed aperture of the substrate, wherein the heat applied, without melting the substrate, melts the target portion of the membrane in forming an aperture in the membrane.

摘要： An apparatus includes a tube (29) configured for insertion into a body of a subject, the tube comprising a plurality of strips (28), which are angled obliquely with respect to a longitudinal axis of the tube, by virtue of the tube being shaped to define a plurality of slits (32) having respective oblique proximal ends and respective oblique distal ends. The distal end of each of the slits is nested between the proximal end of a first other one of the slits and the proximal end of a second other one of the slits such that (i) one of the strips is disposed between the distal end of the slit and the proximal end of the first other one of the slits, and (ii) another one of the strips is disposed between the distal end of the slit and the proximal end of the second other one of the slits.

摘要： In one embodiment, a catheter includes a shaft assembly having a proximal and distal end, which comprises a deflectable segment including lumens running longitudinally therein, electrodes disposed at the distal end, a connector disposed at the proximal end for coupling to processing circuitry, cables disposed in first respective ones of the lumens, each cable electrically coupled to the connector and a respective group of the electrodes, wherein each cable includes a bundle of wires, each wire connected to a respective one of the electrodes in the respective group, an electrical shielding surrounding the bundle, and an electrically insulating jacket surrounding the shielding and sized to allow longitudinal movement of the respective cable within the respective lumen, respective elongated members disposed in second respective ones of the lumens, and connected to the distal end, and a manipulator connected to the elongated members to actuate the distal end via the elongated members.
