    Abstract: A catheter assembly includes an inner liner made of flexible material and an outer layer having a steering mechanism. The steering mechanism includes at least one flat wire and a corresponding lumen through which the flat wire may travel. The steering mechanism may also include at least one pull ring to which the flat wires are attached. A layer of heat shrink material may encompass the outer layer. A braided wire assembly may also be provided in the outer layer, and may be formed by braiding a plurality of flat wires into a wire mesh. The overall cross-section of the catheter assembly is preferably substantially circular. A catheter shaft may include a plurality of segments of differing hardness characteristics. The outer layer typically comprises a melt processing polymer such that the catheter assembly may be laminated using heat.

    Abstract: 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.

    Abstract: Catheter systems and methods are disclosed. An exemplary catheter includes an outer tubing housing and an inner fluid delivery tubing, the inner fluid delivery tubing having at least one fluid delivery port. The catheter also includes a deployment member movable axially within the inner fluid delivery tubing. A plurality of splines are each connected at a proximal end to the outer tubing and at a distal end to deployment member. A seal is provided between the outer tubing and the inner fluid delivery tubing. A gasket is provided between the deployment member and the inner fluid delivery tubing. Both the seal and the gasket are configured to prevent blood or other fluid from ingressing into the outer tubing.

    Abstract: 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 18 in a set position once placed there by actuating the actuator.

    Abstract translation: 本发明是用于偏转管状导管主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，以通过致动致动器将远端18保持在设置位置。
