  • Patent number: 6800091
    Abstract: This patent represents a deformable artificial intraocular lens and method for implantation into the human eye. The lens is used for implantation after cataract surgery. The lens optic consists of one smooth optical surface. The second optical surface is a series of annular concentric rings. The extremely thin lens optic along with the thin haptic can be rolled, folded, or squeezed to pass through a small incision (<1.5 millimeters) in the cornea or sclera of the human eye. The method of correcting a loss of accommodation includes removing the natural crystalline lens from the eye and inserting an intraocular lens in the eye. This lens represents a breakthrough in removal of mass from the lens. After insertion into the eye, the ultra thin lens and haptic design allows the lens to move in the eye providing accommodation for the patient.

  • Patent number: 6786928
    Abstract: This patent represents a deformable artificial intraocular lens for implantation into the human eye. The lens is used for implantation after cataract surgery. The lens optic consists of one smooth optical surface. The second optical surface is a series of annular concentric rings. The rings allow the lens to have extremely thin edges, which reduce glare, halos, and distortion. The extremely thin lens optic along with the thin haptic can be rolled, folded, or squeezed to pass through a small incision (<1.5 millimeters) in the cornea or sclera of the human eye. This lens represents a breakthrough in removal of mass from the lens. The ultra thin lens and haptic design allows the lens to move in the eye providing accommodation for the patient. The lens and haptic design reduces the radial forces on the eye to the point where the naturally occurring pressures in the eye move the lens thus providing accommodation.

  • Patent number: 6693128
    Abstract: This invention describes the novel use of alkyl, alkoxyl, halogenyl, or hydroxy substituted dicinnamoylquinides as therapeutic agents for enhancing adenosine levels in the brain and peripheral organs. These agents are particularly useful in treating human diseases or conditions that benefit from acute or chronic elevated levels of adenosine, such as reperfusion injury, coronary or cerebral ischemia, coronary vasoconstriction, paroxysmal supraventricular tachycardia, hypertension, wound healing, diabetes, inflammation, or sleep disturbances. They can also be used to protect normal cells from chemotoxicity in patients undergoing cancer therapy, and reverse the behavioral effects of caffeine intake.

  • Patent number: 6663256
    Abstract: The present invention discloses an apparatus and method for enhancing the appearance of a subject. The apparatus used for illuminating and drawing attention to the surface of an individual comprises a blocking element, a light source, an energy source, and a mounting element, wherein the blocking element directs light emitted from the light source towards the surface of the subject wearing the apparatus. The method of illuminating and enhancing the appearance of a subject has a surface illuminator, illuminating the light source, reflecting light, attaching the surface illuminator to a surface of the subject, and illuminating the surface of the subject with light reflected from the blocking element. The method also includes the steps of turning the light source off and varying the intensity of the light source.

  • Patent number: 6623966
    Abstract: A composition comprising a nuclear localization sequence and a peptide nucleic acid oligomer (NLS-PNA) is described. Uses of the composition include, but are not limited to: regulation of gene expression, gene therapy, and the production of pharmaceutical nucleic acids and proteins. In addition, the NLS-PNA is useful for scientific and therapeutic transfection and expression of nucleic acids in cells types that previously were resistant to transfection and therapy including quiescent cells, differentiated cells, embryonic stem cells, and eukaryotic cells with intact nuclear membranes. The NLS-PNA can be combined with a membrane transport sequence (MTS) forming a novel compound referred to as an MTS-NLS-PNA wherein the MTS provides transport through the cytoplasmic membrane of a cell.

  • Patent number: 6517577
    Abstract: A crossed haptics attached to an intraocular lens suitable for implantation in either a phakic or an aphakic eye and a method for implanting and releasing the haptics after implantation in the eye, wherein. The lens comprises a very thin, deformable optic having two pairs of haptics attached to the optic by means of two stems 180° apart on the circumference of the optic, the stems being wider and thinner at the base attached to the periphery of the optic, and tapering to a narrower and thicker tip to which each haptic is connected at opposite edges of the stem. Each haptic optionally sweeps about the periphery of the optic so that the angle subtended by a radial line extending from the center of the optic through the center of a footplate and a second radial line extending from the center of the optic through the center of the stem to which it attaches is about 135°. Also disclosed is a haptic design comprising four footplates which are all independently attached to an optic transition area.

  • Patent number: 6511132
    Abstract: The present invention discloses a jam nut, method and system used for attaching wheel liners to vehicle wheels. Each wheel liner attaches to a vehicle wheel when the wheel liner is aligned between the exposed lug bolts of the vehicle wheel and jam nuts that attach to the lug bolts. The wheel liner defines openings that are sized to receive the cylindrical extension members located on the ends of the jam nut without receiving the hexagonal portion of the jam nut.

  • Patent number: 6488707
    Abstract: A deformable, artificial intraocular contact lens for implantation into the human eye to correct normal-vision problems. The lens may be positioned posteriorly from the iris, resting against the anterior surface of the posterior capsule's natural lens. Alternatively, the lens may be positioned in the anterior chamber of the eye. The implanted lens works in conjunction with the cornea and natural lens to provide proper vision, as a substitute for regular contact lens, spectacles, and radial keratotomy. The lens may be designed from a rigid or semi-rigid material. Due to the thinness of the structure, the lens may be rolled and inserted into the eye, minimizing both the length of the corneal incision and the stretching of the cornea.
