  • Microencapsulated fluorinated gases for use as imaging agents
    Patent number: 6132699
    Abstract: It has been discovered that the incorporation of fluorinated gases, especially a perfluorocarbon such as octafluoropropane, into synthetic polymeric microparticles, significantly enhances echogenicity as compared with microparticles having air incorporated therein. The microencapsulated perfluorocarbon is manufactured with a diameter suitable for the targeted tissue to be imaged, for example, for intravenous or oral administration. In one embodiment, bioadhesive microparticles are formed for enhanced imaging of mucosal surfaces.
    Type: Grant
    Filed: September 22, 1998
    Date of Patent: October 17, 2000
    Assignee: Acusphere, Inc.
    Inventors: Howard Bernstein, Julie Ann Straub, Henry T. Brush, Richard E. Wing

  • Filter-type respirator canister
    Patent number: 4365627
    Abstract: An improved canister for a filter-type respirator having an end-of-service life warning device which is located in a position such that all air flowing through the canister flows through the warning device after the air has flowed through at least about 50 volume percent of the filtering material contained in the respirator.
