摘要： A system whereby a magnetic tip attached to a surgical tool is detected, displayed and influenced positionally so as to allow diagnostic and therapeutic procedures to be performed rapidly, accurately, simply, and intuitively is described. The tools that can be so equipped include catheters, guidewires, and secondary tools such as lasers and balloons, in addition biopsy needles, endoscopy probes, and similar devices. The magnetic tip allows the position and orientation of the tip to be determined without the use of x-rays by analyzing a magnetic field. The magnetic tip further allows the tool tip to be pulled, pushed, turned, and forcefully held in the desired position by applying an appropriate magnetic field external to the patient's body. A Virtual Tip serves as an operator control. Movement of the operator control produces corresponding movement of the magnetic tip inside the patient's body. Additionally, the control provides tactile feedback to the operator's hand in the appropriate axis or axes if the magnetic tip encounters an obstacle. The output of the control combined with the magnetic tip position and orientation feedback allows a servo system to control the external magnetic field by pulse width modulating the positioning electromagnet. Data concerning the dynamic position of a moving body part such as a beating heart offsets the servo systems response in such a way that the magnetic tip, and hence the secondary tool is caused to move in unison with the moving body part. The tip position and orientation information and the dynamic body part position information are also utilized to provide a display that allows three dimensional viewing of the magnetic tip position and orientation relative to the body part.

摘要： A method and apparatus for generating a controlled torque of a desired direction and magnitude in an object within a body, particularly in order to steer the object through the body, such as a catheter through a blood vessel in a living body, by producing an external magnetic field of known magnitude and direction within the body, applying to the object a coil assembly including preferably three coils of known orientation with respect to each other, preferably orthogonal to each other, and controlling the electrical current through the coils to cause the coil assembly to generate a resultant magnetic dipole interacting with the external magnetic field to produce a torque of the desired direction and magnitude.

摘要： A catheter and magnet combination adapted for intraparenchymal positioning of the catheter in the body with a magnetic field. The catheter has a proximal and distal ends and a lumen therebetween. A magnet is disposed in the distal end of the lumen so that the distal end of the catheter can be positioned within the body with the aid of an externally applied magnetic field. A tether is attached to the magnet and extends through the lumen and out the proximal end so that the magnet can be removed from the catheter through the lumen once the distal end of the catheter is properly positioned. In one embodiment of the invention, the tether is sufficiently stiff to be able to push the catheter through the tissue. With this embodiment, the magnetic field orients the magnet and thus the tip of the catheter, and some or all of the force for moving the catheter is applied via the tether.

摘要： The invention relates to a coil arrangement for guiding, in a contactless manner, an endoscopic capsule equipped with a permanent magnet in order to diagnose or treat the inside of a patient. The coil arrangement comprises a plurality of individual coils which are arranged in pairs and by means of which the components of a magnetic field and at least four independent gradient fields of a symmetrical, traceless gradient matrix are generated. By arranging the individual coils according to the invention and controlling the same with the help of power amplifiers, the number of magnetic degrees of freedom required for examining the patient can be obtained with fewer individual coils and fewer power amplifiers.
