    摘要: A guide for controlling the orientation of a medical device includes a cannula having a lumen therein for the medical device, and a guide member having a passage therein for receiving and directing the medical device, the guide member being movably mounted in the cannula for movement. The guide member can be magnetically responsive to an externally applied magnetic field, or can be magnetically responsive to an externally applied magnetic field when a magnetic medical device is in the passage, and/or it can be mechanically responsive.

    摘要: A system of navigating a magnetic medical device within that part of a patient located within an operating region of the system, the system comprising magnets, and preferably electromagnets, arranged to provide a magnetic field sufficient to navigate the magnetic medical device within the operating region. There are preferably three magnetic coils arranged in mutually perpendicular planes such that their axes intersect in the operating region. The magnetic coils are sized and arranged so that a patient can easily access the operating region to allow virtually any portion of the patient to be positioned within the operating region. The openness of the magnetic system allows access to the operating region by a bi-planer imaging system.

    摘要: A method of molding a generally hollow front triangle for a bicycle frame of composite materials, such as heat curable structural resins. Layers of the composite material are shaped to form a front triangle shell and this shell is compressed against a mold using at least one inflatable bladder routed to the outside through a passageway passing through a modified bottom bracket sleeve or a modified head tube sleeve.

    摘要: A device and a method for guiding or applying force to a magnetic implant within the body of a patient. The device includes a bed for support of the patient, a set of separately energizable electromagnets or separately controllable permanent magnets so arranged to produce magnetic fields of varying orientations in a treatment region of the patient, and a processor that controls the currents in the electromagnets, or shutters on the permanent magnets to produce a selected magnetic field and/or gradient for guiding or moving the implant. The magnets are configured to allow a medical imaging device to be used to provide a real-time display of an operating procedure in which magnetic guidance is used. The method for guiding the implant includes the placing of the body on the bed, which may be servo-controlled, inserting a magnetically-guided implant into the treatment region, arranging the magnets around the body so that they can supply the necessary magnetic fields and/or gradients through appropriate energization of subsets of the magnets, and applying current or shutter control to subsets of the magnets to provide a guiding magnetic field for the implant, which may occur while real-time medical imaging of the procedure is occurring. The bed may be moved under servo control to provide further control of the direction and magnitude of the magnetic field affecting the implant.

    摘要: Methods and apparatuses for displaying and using a shaped field of a repositionable magnet to move, guide, and/or steer a magnetic seed or catheter in living tissue for medicinal purposes. A moveable magnet assembly and a portion of a patient's body undergoing magnetically-aided surgery are both provided with fiducial markers. The portion of the patient's body is fixed in a location in which the fiducial markers are sensed and located by a set of localizers. The positions of the fiducial markers are determined by a processor, which operates on a stored representation of the magnetic field of a magnet in the magnet assembly to provide a display of the present magnetic field of the magnet. This display may be superimposed over an MRI, X-ray or CAT image during surgery. The repositionable magnet can be an electromagnet. In some embodiments, a computer calculates orientations and currents for an external electromagnet to move the implanted magnetic object in the patient's body through a desired path. The display can provide real-time imaging of the implanted magnetic object in comparison to the desired path as the object is moved.
