    Abstract: An apparatus for deflecting a distal portion of a catheter, a sheath, a medical device, or other flexible elongate member may generally include a handle portion, a pair of adjusting knobs, and deflection wires. The adjusting knobs may be rotatably coupled to the handle portion and operably coupled to the deflection wires. The deflection wires may be in further communication with the distal portion of the flexible elongate member. Rotation of the adjustment knobs may translate or otherwise displace particular deflection wires with respect to the rest of the flexible elongate member, thereby causing the distal portion of the flexible elongate member to deflect. Further, the deflection wires may be oriented such that the distal portion of the flexible elongate member may be deflected in a multitude of directions.

    Abstract: A handle assembly is provided for use in navigating a deformable shaft within a body. The assembly includes a first guide member defining first and second linear channels and a second guide member configured for rotation relative to the first guide member. First and second connectors are disposed within, and movable within, the first and second linear channels along first and second parallel axes, respectively, and are configured for coupling to first and second steering wires, respectively. The assembly includes means, such as a flexible coupling connected to the second guide member and the connectors, for translating rotation of the second guide member into linear movement of the first connector in a first axial direction and linear movement of the second connector in a second axial direction, opposite the first axial direction such that the first and second steering wires move in opposite directions.

    IPC: A61M25/01

    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: Catheter systems include direction-sensitive, multi-polar tip electrode assemblies for electroporation-mediated therapy, electroporation-induced primary necrosis therapy and electric field-induced apoptosis therapy, including configurations for producing narrow, linear lesions as well as distributed, wide area lesions. A monitoring system for electroporation therapy includes a mechanism for delivering electrochromic dyes to a tissue site as well as a fiber optic arrangement to optically monitor the progress of the therapy as well as to confirm success post-therapy. A fiber optic temperature sensing electrode catheter includes a tip electrode having a cavity whose inner surface is impregnated or coated with thermochromic/thermotropic material that changes color with changes in temperature. An optic fiber/detector arrangement monitors the thermochromic or thermotropic materials, acquiring a light signal and generating an output signal indicative of the spectrum of the light signal. An analyzer determines an electrode temperature based on the detector output and predetermined spectrum versus temperature calibration data.
