An apparatus is disclosed for detecting an injection port subcutaneously implanted in a patient's body to enable accurate positioning of an injection needle outside the patient's body to enable the injection needle to be injected directly into the injection port. Also disclosed is a method for detecting the injection port whereby an injection needle can be positioned to be injected directly into the injection port. The apparatus includes a magnetic device that is subcutaneously implanted in the patient adjacent to the injection port to emit a local magnetic field through the patient's skin adjacent to the injection port. A magnetic detector movable externally along the patient's body is capable of detecting the local magnetic field emitted by the magnetic device. This allows the injection port to be located for the insertion of the injection needle directly into the injection port. Alternatively, the apparatus can include a magnetic detector subcutaneously implanted in the patient by the injection port and an exterior magnetic device movable along the patient's skin to emit a magnetic field that is detected by the implanted magnetic detector. Preferably, the magnetic detector includes a semiconductor circuit that is comprised of at least one Hall element. The magnetic device may be a solenoid or a permanent magnet. The injection port can be used to control a restriction device implant designed for treating reflux disease, urinary incontinence, impotence, anal incontinence or obesity.
An apparatus for detecting an injection port adapted to be subcutaneously implanted in a patient, comprising a magnetic device designed to be subcutaneously implanted in the patient at the injection port for emitting a local magnetic field extending through the injection port and a portion of the patient's skin adjacent to the injection port, and a magnetic detector movable externally along the patient's body and capable of detecting said local magnetic field emitted by said magnetic device when said magnetic detector is in a position in front of the implanted injection port, said magnetic detector including a semiconductor circuit, whereby an injection needle put in said position is able to run through the patient's skin right into the injection port.
An apparatus for detecting an injection port subcutaneously implanted in a patient, comprising a magnetic detector designed to be subcutaneously implanted in the patient at said injection port, said magnetic detector including a semiconductor circuit, an exterior magnetic device movable along the patient's skin and adapted to emit a local magnetic field through the patient's skin, said magnetic detector being capable of detecting said local magnetic field when said movable magnetic device is moved to a position in front of said implanted injection port, whereby an injection needle placed in said position is able to be inserted through the patient's skin directly into the injection port.
