摘要： The present invention is a catheter actuation handle for deflecting a distal end of a tubular catheter body, the handle including an auto-locking mechanism. The handle comprises upper and lower grip portions, an actuator, and an auto-locking mechanism. The auto-locking mechanism is adapted to hold a deflected distal end of the catheter in place without input from the operator. When the distal end of the catheter is deflected from its zero position, it typically will seek a return to its zero position, and as a result exerts a force on the actuator. The auto-locking mechanism acts by providing a second force that resists this force from the distal end and holds the distal end in place. As a result, the operator does not need to maintain contact with the buttons to maintain the distal end in a set position once placed there by actuating the actuator.
摘要翻译：本发明是用于偏转管状导管体的远端的导管致动手柄，手柄包括自动锁定机构。把手包括上下把手部分，致动器和自动锁定机构。自动锁定机构适于将导管的偏转的远端保持在适当的位置，而无需操作者的输入。当导管的远端从其零位偏转时，通常将寻求返回到其零位置，并且因此对致动器施加力。自动锁定机构通过提供抵抗来自远端的该力并将远端保持在适当位置的第二力来起作用。结果，操作者不需要保持与按钮的接触，以便通过致动致动器将远端保持在设置位置。

摘要： An apparatus for imparting a tensile force to deflect a distal portion of a catheter while maintaining its exterior dimensions may include a handle grip including a cross-section of generally predetermined exterior dimensions, and a longitudinal axis. A flexible elongate member may include proximal and distal end portions, with the proximal end portion being coupled to the handle grip. An adjustment knob may include a cross-section of generally predetermined exterior dimensions, and is rotatably coupled to the handle grip around the longitudinal axis. An elongate deflection member may be operably coupled to the adjustment knob and to the distal end portion of the elongate member. Rotation of the adjustment knob may impart a tensile force to the deflection member thereby causing the distal end portion of the elongate member to deflect from a prior configuration while maintaining the generally predetermined exterior dimensions of the handle grip and the adjustment knob.

摘要： An ablation catheter is disclosed having proximal and distal ends and an external surface, a lumen contained within the catheter body, a plurality of openings in the surface of the catheter, wherein the openings are in communication with the lumen, one or more electrodes secured within the catheter within the lumen and a source for conductive media to be introduced into the lumen to contact the electrode. The ablation catheter also may contain a conductive media flow control system which controls the flow of the conductive media through the openings in the surface of the catheter. Also disclosed is a process for ablation of human tissue which includes introducing an ablation catheter into the human body to a location to be ablated, passing a conductive media through a lumen of the catheter to contact one or more electrodes, passing the conductive media through the openings in the catheter body to contact the tissue to be ablated, and conducting energy from the electrode through the conductive media to the tissue for a sufficient period of time to ablate the tissue.

摘要： The present invention is a handle for controlling the deflection of a distal end of a catheter body. The catheter body includes first and second deflection wires that extend through the catheter body from the distal end of the catheter body. The handle comprises a slide base, an adjustment knob, a first slide and a second slide. The slide base includes a first end, a second end, and a slide compartment longitudinally extending through at least a portion of the slide base. The adjustment knob is rotateably connected to the first end of the slide base and includes a hole extending through the knob, wherein at least a portion of an inner diameter of the hole includes an internal right thread and an internal left thread. The first slide is located in the slide compartment, is adapted to be coupled to the first deflection wire, and includes an external right thread. The second slide is located in the slide compartment, is adapted to be coupled to the second deflection wire, and includes an external left thread. The internal threads of the knob engage the threads of the slides. Consequently, in operation, rotation of the adjustment knob causes the slides to displace in opposite directions within the slide compartment and the distal end of the catheter body to deflect accordingly.
