    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.

    Abstract: A deflectable catheter shaft section is disclosed comprising an elongated body extending along a longitudinal axis and comprising a distal end and a proximal end; and a plurality of lumens extending along the longitudinal axis of the elongated body, wherein at least one of the lumens is abutting at least another one of the lumens. A catheter comprising the deflectable catheter shaft section and a method of manufacturing the deflectable catheter shaft section are also disclosed. A catheter incorporating a deflectable catheter shaft section can further comprise first and second compression coils disposed over pull wires located within the catheter, wherein the compression coils are unattached to the catheter or components thereof, but can be constrained by a shaft coupler at a distal end of each of the compression coils and by at least a portion of a handle assembly at a proximal end of each of the compression coils.

    Abstract: A catheter with a mechanism for omni-directional deflection of a catheter shaft includes a shaft assembly and a controller. The shaft assembly includes a first tubular component that has a preformed curvilinear distal section, a second, substantially straight tubular component with a main axis and an outer shaft. The first and second components are configured for slidable movement therebetween while preserving common rotation so that when the second component is axially moved in a distal direction, the second component deflects the preformed curvilinear section towards the main axis while orientation of the outer shaft is preserved. The controller is configured to effect relative axial movement between the first and second components as well as to effect rotation of the first and second components (and thus also of the preformed curvilinear distal section) without any rotation of the shaft relative to the handle. Varying the deflection of the preformed curvilinear section in combination with variable rotational movement achieves omni-directional distal tip bending.

    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.

    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.
