    Abstract: A catheter includes a flexible tubing having a proximal end and a distal end. The catheter also includes an electrode assembly attached to the distal end of the flexible tubing and having a first magnet therein. The electrode assembly further includes an electrically conductive tip electrode and an electrically nonconductive coupler which is connected between the tip electrode and the distal end of the flexible tubing. The coupler and the tip electrode are coupled by an interlocking connection. The catheter also includes a second magnet spaced from the electrode assembly along a longitudinal axis of the tubing. The first magnet and the second magnet are responsive to an external magnetic field to selectively position and guide the electrode assembly within a body of a patient.

    Abstract: A magnetically-guided catheter includes a tip positioning magnet in the distal end portion thereof configured to interact with externally applied magnetic fields for magnetically-guided movement. The magnet may be geometrically asymmetric, for example, a C-shape in radial cross-section, so as to allow side-loading of an irrigation fluid lumen and other wire(s) or lines during fabrication. The outer shaft includes a plurality of segments, including a generally soft segment at the distal end thereof for magnetically-guided navigation. The fluid lumen, which extends through the outer shaft, and further extends completely through the magnet for coupling to the ablation electrode irrigation fluid inlet, is constructed so that its mechanical properties (i.e., flexibility) substantially matches that of the outer shaft. The combination of the outer shaft, inner fluid lumen and positioning magnet has interoperability with a broad range of ablation tip assemblies.

    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.
