  • Patent number: 6428502
    Abstract: A lacrimal cannula, which is used for the removal of plugs or obstructions from mammalian lacrimal canaliculi having a punctum, includes a body having a distal portion, a proximal portion, an external annulus disposed proximate the distal portion, and a hollow bore for fluid delivery from the distal portion. The external annulus has an outer diameter greater than the outer diameter of the distal portion. The distal portion is inserted into the mammalian punctum without dilating the punctum and the external annulus has a generally spherical geometry which forms a seal with the external surface of the punctum without dilating the punctum and without the necessity of forcefully pressing the cannula against the punctal tissue to create a seal. The distal portion also has a relatively short length so that the distal portion is easily inserted into the canaliculus without contacting the plug or obstruction and thus interfering with the formation of the punctal seal.

  • Patent number: 5874469
    Abstract: Fluoroalkyl hydrocarbons as vehicles for pharmaceutical drugs are disclosed. These vehicles are particularly well-suited for delivering drugs which are insoluble in water or chemically unstable in aqueous media. Pharmaceutical solution compositions based on these vehicles have long shelf lives and provide improved drug bioavailability. In addition, the pharmaceutical compositions of the present invention are nonaqueous, and therefore do not require preservatives or tonicity agents. The invention is particularly useful in the field of ophthalmology.

  • Patent number: 5858345
    Abstract: Ophthalmic compositions containing biocompatible, bioadhesive polymerizable amphipathic mesophase materials useful for repairing retinal tissue tears or retinal detachments are disclosed. In one embodiment, the polymerizable materials, which comprise substituted fluoroalkyl or perfluoroalkyl monomers having anionic, cationic, and/or nonionic surface active functionality in the unsaturated fluorophobic ends, are polymerized in vivo to provide effective, long-lasting repair of torn, ruptured or detached retinal tissue. Ophthalmic applications of these materials are not limited to retinal repair.

  • Patent number: 5618800
    Abstract: Drug delivery vehicles which reversibly increase in either loss modulus or storage modulus, or both, upon contact with the eye, skin, mucous membrane or body cavity are disclosed. The vehicles contain one or more nonionic substituted cellulose ethers and do not require a charged surfactant or a pH-sensitive polymer for such increase in loss modulus or storage modulus, or both, upon administration. In one embodiment, the vehicles gel upon instillation in the eye.

  • Patent number: 4440356
    Abstract: Machine for separating and longitudinally slitting thin sheet, especially double-rolled aluminum sheet or foil, and for winding it onto two winding shafts in abutting strip coils, each winding station including a displaceable cylinder-biased winding carriage with a deflecting roll and a pressure roll defining a terminal sheet run unaffected by the carriage position. Slitting knives arranged on a rotatable swivel shaft in the winding carriage reach into the sheet path in its terminal run, just ahead of the winding point, the slitting knives being retractable into a safe position through rotation of the swivel shaft.
