摘要： An energy delivery apparatus for delivering electrical energy at a target location, the energy delivery apparatus being usable in combination with a magnetic field. The energy delivery apparatus includes an electrical conductor, the electrical conductor having a substantially elongated configuration; an electrode for delivering the electrical energy at the target location, the electrode being electrically coupled to the electrical conductor and located at a predetermined location therealong; and a guiding element mounted to the electrical conductor in a substantially spaced apart relationship relative to the electrode, the guiding element including a magnetically responsive material. The energy delivery apparatus is constructed such that a movement of the guiding element causes a corresponding movement of the electrode. The magnetic field is used to move the guiding element in order to position the electrode substantially adjacent to the target location.

摘要： Generally, the shielded x-ray source of the present invention has a cast shield of an iron based material substantially enclosing and closely conforming to the x-ray tube to shield the x-ray tube imaging beam from interference from magnetic fields. The method of the present invention includes providing a shield cast from an iron-based material in a shape having a cavity to receive and closely conform to the x-ray tube, and installing the cast shield around the x-ray tube. The magnetic surgical system comprising at least one magnetic for magnetically navigating a medical device in an operating region in a patient's body, and an imaging apparatus including at least one x-ray tube for imaging the operating region. A cast shield of an iron-based material substantially enclosing and closely conforming to the at least one x-ray tube.

摘要： A method of localizing a medical device inside a patient's body, the method comprising: transmitting ac magnetic signals between a plurality of points of known location outside of the patient's body and a plurality of points on the medical device inside the patient's body, the signals transmitted between at least some of the points comprising at least two different frequencies; and receiving the transmitted ac magnetic signals and processing the received signals to determine the position of the points on the medical device, and thus the location of the medical device, this processing including correcting for the affects of metal in the vicinity by using the transmitted and received signals at different frequencies. In an alternate embodiment, a reference device is provided inside the patients' body, and the medical device is localized relative to the reference catheter. The use of signals comprising at least two frequencies may or may not be used in this relative localization embodiment, but preferably is used at least to localize the reference catheter.
