摘要： An ablation catheter comprises a shaft and at least one ablation electrode which may be fixed or movable relative to the shaft. An insulating cap is placed over portions of the electrode which are susceptible to high current concentrations when RF energy is applied to the electrode. Typically, such portions occur in the region of abrupt surface transitions such as the edges of the electrode.

摘要： A steerable catheter includes control handle having a generally tubular housing with a longitudinal slot therein in which an axially or longitudinally movable tow-part slideblock resides, and a generally cylindrical, rotatably mounted thumbwheel surrounding a distal portion of the tubular housing, for controlling the axial translation of the slideblock. The pullwire passes into the distal end of the control handle and is only secured to the proximal part of the two-part slideblock so as to prevent the user from placing the pullwire under compression. A tip radius adjusting wire is attached to and extends distally from a slide actuator in the control handle into and through the main catheter shaft portion. The free distal end of the tip radius adjusting wire is selectably locatable at different positions. The radius of curvature of the tip portion, when deflected, depends upon how far distally into the deflectable tip portion the radius adjusting wire has been advanced by the user. The electrode catheter thus has a deflectable tip whose radius of curvature is adjustable over a relatively wide range.
摘要翻译：可操纵的导管包括控制手柄，其具有大致管状的壳体，其中具有纵向狭槽，其中轴向或纵向移动的牵引部件滑块位于其中，以及围绕管状壳体的远端部分的大致圆柱形可旋转地安装的指轮，用于控制轴向幻灯片的翻译。拉线进入控制手柄的远端，并且仅固定到两部分滑块的近端部分，以防止使用者将拉线放置在压缩状态。尖端半径调节线附接到控制手柄中的滑块致动器并远离其延伸并且穿过主导管轴部分。尖端半径调整线的自由端可选地位于不同位置。尖端部分的弯曲半径在偏转时取决于使用者已经使半径调节线前进到可偏转尖端部分的远端。因此，电极导管具有可偏转的尖端，其弯曲半径在相对宽的范围内是可调节的。

摘要： Novel apparatus and methods for irrigating an electrode of a catheter are disclosed. Among other things, a catheter is disclosed that comprises a shaft portion including a fluid passage to conduct fluid, an electrode coupled to a distal end of the shaft portion, and a handle portion coupled to a proximal end of the shaft portion. A portion of the fluid passage defines an opening in the shaft portion. The opening is constructed and arranged such that when fluid is conducted through the fluid, at least some of the fluid will contact the electrode after passing through the opening in the shaft portion.

摘要： This invention is a medical device (10) including an elongated shaft (16) that is twisted through a predetermined angle. One or more lumen (22) are formed in the shaft (16), and twist through the predetermined angle as well. A pull wire (29) extends through one of the lumen (22), and attaches to a distal portion of the elongated shaft (16) at an off axis location. By tensioning the pull wire (29), the medical device (10) can assume various complex curves, depending on the degree of twist imparted to the shaft (16).

摘要： Catheters for mapping and/or ablation are disclosed. In one embodiment, the catheter comprises a handle, a flexible shaft, a tip assembly, and a cable. The handle includes an actuator and is attached, at its distal end, to the proximal end of the flexible shaft. The flexible shaft has a longitudinal axis that extends along a length of the shaft. The proximal end of the tip assembly is attached to the distal end of the shaft and includes a fixed bend of approximatley ninety degrees relative to the longitudinal axis of the shaft. The distal end of the tip assembly includes an arcuate curve having a diameter. The arcuate curve is oriented in a plane that is approximatley perpendicular to the longitudinal axis of the shaft. The cable is attached to the actuator and the distal end of the tip assembly, and extends through the shaft. The cable is adapted to change the diameter of the arcuate curve in response to movement of the actuator.
