Abstract: A guide wire comprising an elongate, flexible core having a proximal region, a proximal end, a distal region, and a distal end, and the distal region having a tapered portion; a plurality of wire strands wrapped helically parallel to one another and disposed on at least a portion of the tapered distal region of the core; a polymer tie layer disposed on at least a portion of the plurality of wire strands; and a lubricious polymer layer disposed on the polymer tie layer.

Abstract: An electrophysiology catheter includes a tube having a proximal end, a distal end, and a lumen therebetween. The tube is preferably comprised of multiple sections of different flexibility, arranged so that the flexibility of the catheter increases from the proximal end to the distal end. There is a first generally hollow electrode member at the distal end. A magnetically responsive element is disposed at least partially in the hollow electrode, for aligning the distal end of the catheter with an externally applied magnetic field. The end electrode can have openings for delivering irrigating fluid, and/or a sleeve can be provided around the tube to create an annular space for the delivering of irrigating fluid. A temperature sensor can be provided to control the operation of the catheter. A localization coil can also be to sense the position and orientation of the catheter.

Abstract: An electrophysiology catheter has a proximal end and a distal end. There is a first generally hollow electrode member at the distal end, having a generally cylindrical sidewall and a dome shaped distal end. There is a magnet member at least partially within the hollow electrode member. The magnet member may be a permanent magnet or a permeable magnet material. The magnet is sufficient size and strength to align the distal end of the electrophysiology catheter inside the body of a patient with an externally applied magnetic field.
