Abstract
A device for locating a port, facing the exterior of a patient, on a medical implant has at least one magnet and a detector arranged to sense magnetic fields. The magnet is associated with the implanted port and the detector is arranged to sense the magnetic field from the outside of the patient's body and, on the basis thereof, determine the location of the port. Alternatively, the detector is associated with the (implanted) port and the magnet is intended to be moved across the area above the detector on the exterior of the patient's body to then determine the location of the port from the magnetic field detected. The device can alternatively use a coil which is associated with the (implanted) port and a ferromagnetic element is moved on the exterior of the patient's body over the area above the coil. Changes in the inductance of the coil when the ferromagnetic means is moved are monitored and, therefrom, the position of the port is identified.
