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 catheter has an electrode assembly adapted for use on an ostium and a stabilizing assembly movable between a stowed position within the catheter and a deployed position in the tubular region of the ostium. The stabilizing assembly has a balloon member that can be extended distally into the tubular region and inflated to wedge itself in the tubular region for anchoring the electrode assembly. The balloon member is mounted on an elongated extender that extends through the catheter and is provided with longitudinal movement to advance and withdraw the balloon between the stowed and deployed positions.

摘要： A catheter having a distal assembly with multiple spines with proximal ends affixed to the catheter and free distal ends. The spines have different lengths so distal ends of the spines trace different circumferences along an inner tissue surface of a tubular region to minimize risk of vein stenosis. The spine lengths can be configured so that the distal ends trace a helical pattern. The distal assembly may have a plunger which deflects the spines when moved longitudinally relative to the distal assembly. The catheter may include a second distal assembly distal of a first distal assembly wherein the first and second distal assemblies are separated by a fixed distanced or an adjustable distance.

摘要： A catheter includes an elongated body having a longitudinal axis, a distal assembly distal the elongated body, the distal assembly having a tapered helical form comprising a larger, electrode-carrying proximal loop and a smaller, softer distal loop, and a shape-memory support member extending through at least the proximal loop. For example, the helical loop subtends at least about 720 radial degrees, with the proximal loop subtending about 360 radial degrees, and the distal loop subtending about 360 radial degrees. The softer distal loop with a straight distal end atraumatically guides the distal assembly into a tubular region so that the larger proximal loop can sit on the ostium of the tubular region with improved electrode and tissue contact.

摘要： Endoscopic devices methods and devices are provided for attaching opposed walls of tissue. The methods and devices can be used to deliver a plurality of fasteners to opposed tissues, and suture extending through the fasteners can be used to pull the tissues together. The suture can be pre-woven through the fasteners, thus allowing for a quick and simply deployment. While the various methods and devices disclosed herein can be used in a variety of procedures, in certain exemplary embodiments the methods and devices are used to pull together opposed walls of the stomach to form a stomach pouch within the stomach which reduces the rate of gastric emptying.

摘要： A catheter includes an elongated body, a distal assembly with a shape-memory member defining a generally circular form, and a control handle adapted to actuate a deflection puller wire for deflecting a portion of the elongated body, and a contraction wire for contracting the generally circular form. The generally circular form which carries at least one ring electrode has an off-edge configuration relative to the elongated body such that a longitudinal axis of the elongated body does not intersect the circumference of the circular form and the generally circular form spirals about the longitudinal axis of the elongated body. Moreover, the circular form can have an on-axis configuration such that the longitudinal axis of the elongated body is axially aligned with a central longitudinal axis of the circular form, or an off-axis configuration such that these axes are axially offset from each other. In a more detailed embodiment, the catheter has a distal assembly with a helical form or a crescent form carrying a plurality of irrigated ablation ring electrodes and a plurality of smaller ring electrodes adapted for impedance recording or PV potential recording. A support member with shape memory extends through the distal assembly to provide the helical or crescent form. The support member has a varying stiffness along its length, for example, a decreasing stiffness toward a distal end of the support member. The support member can also be hollow so that it can receive a mandrel whose stiffness is greater than that of the support member.
