  • Patent number: 7354416
    Abstract: Methods, devices and systems for draining fluid from the eye and/or for reducing intraocular pressure. A passageway (e.g., an opening, puncture or incision) is formed in the lamina cribosa or elsewhere to facilitate flow of fluid from the posterior chamber of the eye to either a) a subdural location within the optic nerve or b) a location within the subarachnoid space adjacent to the optic nerve. Fluid from the posterior chamber then drains into the optic nerve or directly into the subarachnoid space, where it becomes mixed with cerebrospinal fluid. In some cases, a tubular member (e.g., a shunt or stent) may be implanted in the passageway. A particular shunt device and shunt-introducer system is provided for such purpose.

  • Patent number: 5855922
    Abstract: Compositions and processes for the prophylaxis and therapeutic treatment of wounds, chronic non-healing wounds, burns, disease and other dermal disorders are disclosed. The compositions of the present invention comprise aqueous solutions of a metal chlorite having a concentration of from about 0.002% to about 0.5% by weight of metal chlorite. The process of the present invention comprises treating the dermal disorder with an aqueous solution of from about 0.002% to about 0.5% by weight of a metal chlorite. Wounds, chronic non-healing wounds, burns and other dermal disorders treated in this manner heal more quickly and with reduced scar formation. The antiseptic compositions and processes of the present invention exhibit anticollagenous activity such that the characteristics of the healed skin, such as elasticity and tensile strength, are similar to undamaged skin.
