    摘要： An intravascular catheter system for implanting a radially expandable stent within a body vessel including a catheter comprising an inner lumen tube, an inflation lumen tube, an inflatable balloon and at least one free standing built-up layer affixed to the outer diameter of the inner lumen tube, the built-up layer being internal to the balloon. A stent is mounted coaxially upon the balloon, the built-up layer extends coaxially within the stent but does not extend beyond the proximal and distal ends of the stent. The built-up layer is sufficiently thick as to cause the balloon to expand evenly and the stent to deploy uniformly. The method of manufacturing the built-up layer includes forming the layer from shrink wrap tubing or alternatively forming the layer from molded ultraviolet light curing adhesive.

    摘要： An ablation therapy system and systematic method is provided for treating continuous atrial fibrillation. The therapy system includes a Multi-Channel RF Ablation Generator, an ECG interface, an assembly of at least three ablation catheters, and an ECG interface operably coupling and interfacing the catheters to both an ECG unit and the RF Ablation Generator. The systematic method includes transseptally accessing the Left Atrium (LA) through the septum of the patient's heart, and performing an endocardial pulmonary vein ablation procedure on the pulmonary vein ostial tissue surrounding one or more pulmonary veins in a manner treating aberrant conductive pathways therethrough. After performing the pulmonary vein ablation, the method further includes performing an endocardial atrial septum ablation procedure on the septal tissue in a manner treating aberrant conductive pathways therethrough.

    摘要： Catheters and methods for obtaining monophasic action potential (“MAP”) electrograms include a flexible catheter body defining a longitudinal axis, and a distal assembly affixed to the catheter body distal end defining a distal tip. The distal assembly has at least three MAP recording electrodes, and at least one reference electrode for determining reference potential. The recording electrodes are each positioned a radial distance from the longitudinal axis in at least three different radial directions, defining a recording geometry substantially having radial symmetry. The reference electrode is a longitudinal distance from the recording geometry. Optional features include a steerable catheter shaft, one or more radio-frequency ablation electrodes, and a dedicated pacing electrode. Different possible embodiments include a dome housing having the recording electrodes in a fixed spatial arrangement, and a distal loop assembly having an array of electrodes on at least three flexible loop elements.
