A system for the detection, location and extraction of an intrauterine device ("IUD") including a magnetic IUD, a locator probe to be used intravaginally and an extractor probe to be used intrauterinally, both containing at least one Hall effect generator. The probe is inserted into the patient and an indicator means is provided to communicate the presence of the IUD, in the case of the locator, or the distance of the IUD from the probe, in the case of the extractor. After positioning the extractor next to the IUD using the indicator for guidance, grasping means in the extractor is actuated to effect temporary attachment of the IUD to the extractor which is then withdrawn from the uterus. |
