Abstract: A device implantable into the eye is provided that includes an elongate duct portion having a longitudinal axis. The duct portion defines at least one lumen that extends from a distal end to a neck spaced longitudinally from the distal end. The device further includes a second portion that includes two tubular segments that extend or flare outwardly from the neck opposite one another relative to the longitudinal axis. The second portion includes at least one outlet in fluid communication the at least one lumen of the duct portion to permit fluid to flow through the device. In embodiments, the first duct portion and the second portion are formed together as a unitary structure. The two tubular segments of the second portion can extend or flare outwardly from the neck opposite one another relative to the longitudinal axis in a Y configuration.

Abstract: A method of making an ocular lens device (and resulting lens device) from a polyolefin copolymer material having a crosslinking component, wherein the material is processed to remove unwanted reaction byproducts that can contribute to reduced transparency of the polyolefin copolymer material in the ocular environment of the eye.

Abstract: A surgical implant device for treating glaucoma includes an elongate duct structure formed from a material comprising polyisobutylene and a glassy segment. The material of the elongate duct structure preferably has a general block structure with a central elastomeric polyolefinic block and thermoplastic end blocks (e.g., a triblock polymer backbone comprising polystyrene-polyisobutylene-polystyrene). The elongate duct structure provides a fluid passageway for diverting aqueous humor from the anterior chamber of the eye. Preferably, the elongate duct structure defines a lumen channel having an inside diameter between 0.05 mm and 0.3 mm. The material of the elongate duct structure is biocompatible and biostable. Moreover, the material will not encapsulate in the eye and thus provides an unobstructed flowpath that diverts aqueous humor from the anterior chamber. Different embodiments of the implant device divert the aqueous humor to different parts of the eye (e.g.

Abstract: A method for producing ionically cross-linked gellan gum includes dissolving the material in a first liquid solution that includes a dissolving liquid. The first liquid solution is applied to a workpiece to form a polysaccharide-based coating on the workpiece. The coating is dried to remove a substantial portion of the dissolving liquid. Subsequent to drying, the coating is exposed to a second liquid solution that includes a compound that promotes ionic cross-linking of the coating. In the preferred embodiment, the dissolving liquid comprises water and possibly a polar solvent. The ionic cross-linking compound preferably comprises a divalent cation such as calcium (Ca2+), or possibly strontium (Sr2+), magnesium (Mg2+), barium (Ba2+), or other multivalent ions. Such a method forms a uniform ionically cross-linked film and/or coating for diverse applications, including medical devices such as implantable vascular grafts, stent-grafts and/or stents.
