摘要： A shield for controlling a magnetic field emanating from a magnetic in a magnetic medical treatment instrument has the form of a circular shaped band with opposite open ends and a center axis extending perpendicularly between the open ends. The magnet in the magnetic medical treatment instrument moves about an operating table having a surface upon which a patient being operated on by a physician reposes. The circular shaped shield surrounds the magnet and is spaced away from the magnet in a manner to allow the physician to enter the interior of the band and operate on the patient. The band has opposite first and second parallel planar portions. The top surface of the operating table and the first and second planar portions of the band are parallel to each other. The operating table has a length and a width, and the length of the operating table is parallel to the center axis of the band.

摘要： 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. At least one magnetically responsive element is disposed at least partially in the hollow electrode, for orienting the distal end of the catheter with an externally applied magnetic field. Multiple magnets can be distributed over the distal portion of the device. 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 included to sense the position and orientation of the catheter.

摘要： Methods of designing an x-ray tube shielded for operation in static and dynamic externally applied magnetic fields are described. The methods include passive shielding of the insert frame, housing, design of an external shield envelope, tube port, tube collimator, and combinations thereof.

摘要： A method of treating vessel occlusions including chronic total occlusions (CTO) of the coronary arteries is presented that relies on remote navigation of a remotely steered medical device to the occlusion and controlled application of ablative energy or mechanical push together with real-time local imaging of the vasculature or real-time vessel wall sensing. The combinative use of remote navigation methods and real-time imaging or real-time sensing enables crossing of elongated lesions and CTOs, calcified lesions and CTOs and lesions and CTOs located at vessel branches.
