  • Patent number: 4727866
    Abstract: 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grasping means in the extractor is actuated to effect temporary attachment of the IUD to the extractor which is then withdrawn from the uterus.

  • Patent number: 4728614
    Abstract: A stable mutant human T cell line is disclosed which secretes a high titer suppressor inducer factor. This suppressor inducer factor in turn induces production of a T cell suppressor factor which suppressed mitogen-induced T cell proliferation at high dilution. Also disclosed is a general method for mutating lymphoblastoid cell lines to yield mutants secreting enhanced levels of lymphokines.
