Title: Apparatus for preparing cornea material for tabbed (sutureless) transplantation

Full Record
Other Related Research

Abstract

A tool and a method for preparing a donor material used in sutureless corneal transplants uses a first cutting portion to prepare a donor blank having tabbed portions extending outwardly radially. A second cutting portion is used to cut the central portion of the blank. The tool is used as a guide member for the second cutting portion. In one embodiment the tool has slits laterally defined therethrough which allow the tabbed portions of the donor material to be thinned to a desired thickness using a scalpel. In an another embodiment the second cutting portion is a round trephine which is used to simultaneously trim each of the tabbed portions.

Method and apparatus for mounting a dichroic mirror in a microwave powered lamp assembly using deformable tabs

Patent Ury, Michael [Bethesda, MD]; Sowers, Frank [Frederick, MD]; Harper, Curt [Wheaton, MD]; ...

A microwave powered electrodeless lamp includes an improved screen unit having mesh and solid sections with an internal reflector secured at the juncture of the two sections to reflect light into a light-transmitting chamber defined in the lamp microwave cavity by the reflector and the mesh section. A discharge envelope of a bulb is disposed in the light-transmitting chamber. Light emitted from the envelope is prevented by the reflector from entering the cavity portion bounded by the solid section of the screen. The reflector is mounted in the cavity by tabs formed in the screen unit and bendable into themore » « less

Process and apparatus for preparing textured crystalline materials using anisotropy in the paramagnetic susceptibility

Patent Holloway, Aleksey [522 N. 32nd St., Omaha, NE 68131]

The present invention discloses a process and apparatus for forming textures in materials. The process comprises heating a material having an anisotropy in the paramagnetic or diamagnetic susceptibility within a magnetic field. The material is heated to a temperature approaching its melting point while a magnetic field of at least 10.sup.4 Oe is simultaneously applied. The process and apparatus produce highly textured bulk and elongated materials with high current densities below critical superconducting temperatures.
