  • Patent number: 6397849
    Abstract: Intrascleral injection of a therapeutic or diagnostic material at a location overlying the retina provides a minimally invasive technique for delivering the agent to the posterior segment of the eye. The procedure also allows for close proximity of the material to the targeted site and can be effectively used to treat conditions associated with the posterior segment of the eye, including macular degeneration, vein occlusion, and diabetic retinopathy. The sclera can be used to hold a depot of the material such as for sustained released or as a conduit for propelling material through whereby the material is delivered immediately to the underlying tissues but without physically penetrating the sclera with an instrument or otherwise unreasonably traumatizing the eye.

  • Patent number: 6372245
    Abstract: A controlled release medicament delivery system comprises a plasticized bioerodible polymer, such as a polyorthoester. Medicament desirably is entrapped in the plasticized polymer. The resulting delivery system is able to release the medicament in a controlled and sustained manner. The formulation is particularly advantageous for use as a once-a-day eyedrop. During preparation, the polymer may be heated to an elevated temperature for a sufficient time to substantially reduce its molecular weight.

  • Patent number: 6309374
    Abstract: The present invention relates to an apparatus and method for using the apparatus for injecting an agent into a tissue, particularly into thin tissues such as the sclera of the eye. The invention provides an apparatus and method for effectively imbedding a needle into a tissue at a predetermined penetration approach angle and penetration distance thereby reducing the risk of penetrating the full thickness of the tissue. The invention includes a support element and a needle guide platform disposed on the support element with an external support surface and a channel extending therethrough and terminating in an aperture at the support surface. A needle disposed in the channel is axially movable along an axis of injection through the channel. The needle is movable from a first retracted position to an extended position corresponding to the penetration distance, along the axis of injection.
