  • Patent number: 11957402
    Abstract: A forceps includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and includes a pair of first and second jaw members. One or both of the first and second jaw members is movable relative to the other jaw member from a clamping position to an open position. A resilient member operably couples to the first and second jaw members. The resilient member is configured to bias the first and second jaw members in the clamping position and provide a closure force on tissue disposed therebetween.

  • Publication number: 20020127699
    Abstract: Compositions, formulae, devices and methods for the detection of target microorganisms, such as by visual immunoprecipitate assay, enzyme linked immunoassay, chemiluminescence, immunoblotting, or similar detection technology, wherein detection requires the discrimination among closely related genera, species and strains of antigenically related microorganisms based on immunological reactivity of a highly conserved antigen epitopes with a reagent system comprised of an antibody linked to a detecting reagent. The invention permits a detectable event to occur by exposing inaccessible but highly conserved and specific antigen epitopes to the detecting reagent. Exposure of such antigen epitopes without inactivating microbial metabolism allows for specific detection.

  • Patent number: 4975278
    Abstract: This invention relates to a novel method for the delivery of cytotoxic drugs to tumor cells by the administration of a tumor-specific antibody-enzyme conjugate that binds to the tumor cells, and the additional administration of a prodrug that is converted at the tumor site, in the presence of the antibody-bound enzyme, to an active cytotoxic drug. According to preferred embodiments of this invention, antibody-enzyme conjugates containing the enzyme, alkaline phosphatase ("AP"), have been used in conjunction with the novel prodrug, etoposide-4'-phosphate or 7-(2'-aminoethyl phosphate)mitomycin or a combination thereof, to effect killing of tumor cells. According to another embodiment of the invention, an antibody-enzyme conjugate containing the enzyme, penicillin V amidase ("PVA"), has been used in conjunction with a novel prodrug, N-(p-hydroxyphenoxyacetyl)adriamycin to effect killing of tumor cells.
