  • Patent number: 4228797
    Abstract: A chemical contraception system is described in which the spermicidal chemical, for example, "Nonoxynol-9", is provided in a powder or tablet form and is dissolved in a solvent, primarily water, immediately before use. The solution containing the spermacide is then allowed to soak into an applicator matrix, such as a sponge or pad. The spermicide-impregnated matrix is inserted into the vagina and later removed. The system can be provided in kit form (FIGS. 1 and 2) including a storage container for the powder, a mixing container, and a measuring spoon, or in a pre-packaged form where the chemical has already been added to the sponge.Among the preferred embodiments of the system are the use of the spermicidal chemical in powder or tablet form and the use of a sponge for vaginal retention of the spermicidal solution.

  • Patent number: 4216860
    Abstract: An improved medical device container and method of manufacture thereof, wherein the container is adapted to be opened manually and dispense the contents onto a sterile field without the need of manual contact. The container is a thermally formed blister package and features a tray having at least one depression which is sized and shaped to receive a sterile medical appliance, and a pliable backing sheet having at least one flexible insert affixed thereto. The backing sheet is bonded to the periphery of the tray, and the insert engages the medical device and urges it into firm contact with a portion of the depression to secure the device therein. The backing sheet is adapted to be manually peeled away from the tray and thereby pull the flexible insert out of the depression so that the medical device may fall freely onto a sterile location without the need for manual contact.

  • Patent number: 4122556
    Abstract: The invention contemplates improved techniques for making lens implants for use in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens, and the replacement being installed in the pupil at the iris as the operative step following removal of the cataracted lens. The lens produced by the inventive method features adapter structure assembled to an intra-ocular lens element and having first and second pluralities of radially outward stabilizing feet, the feet of one plurality being in angularly spaced and interlaced relation with the feet of the other plurality; and the respective pluralities of stabilizing feet are on opposite sides of the iris, enabling the iris to retain and position the implanted lens. At least two diametrically opposed feet are resiliently compliant and have openings for removable engagement with a manipulative tool.
