摘要： PROBLEM TO BE SOLVED: To provide a catheter that includes a distal assembly having multi-spines, each having a proximal end and a free distal end attached to the catheter.SOLUTION: Spines 14 have different lengths, and therefore, distal ends of the spines draw different peripheral diameters along an inner tissue surface of an annular region for minimizing a risk of the venous stenosis. The length of each spine may be configured that the distal end draws a spiral pattern. A distal assembly 18 may include a plunger that, when moving longitudinally with respect to the distal assembly, deflects the spines. The catheter 10 may include a second distal assembly at a distal end of a first distal assembly, and the first distal assembly and the second distal assembly are located at a prescribed distance apart or separated by an adjustable distance.

摘要： PROBLEM TO BE SOLVED: To provide a catheter which fits different sizes of ostia.SOLUTION: The catheter 10 includes an elongated body 12, a shape-memory member defining a generally circular form, and a control handle 16 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.

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 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.

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. Q \ / T- N3'. .- M! 3: ,-2-f I '~-:: C) _ 00 co0
