    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： A surgical camera assembly includes a proximal member defining a longitudinal axis and a distal member defining a pointed tip configured to puncture tissue to permit insertion of the surgical camera assembly therethrough. The distal member is pivotably coupled to the proximal member and is movable relative thereto between a first position, wherein the distal member is aligned with the longitudinal axis, and a second position, wherein the distal member is angled off the longitudinal axis. First and second surgical cameras are disposed within the distal member in fixed position and longitudinally-spaced relative to one another. Each of the cameras is oriented to define a viewing area in a direction extending from an outer lateral periphery of the distal member. The cameras are configured to produce video images that are used in conjunction with one another to provide a three-dimensional video image of the internal surgical site.
