| 20100331975 | FIBER MATRIX FOR MAINTAINING SPACE IN SOFT TISSUES - A fiber matrix is provided for maintaining space in soft tissue, for example for use in procedures for assisting drainage of aqueous humor from an eye to treat glaucoma. The fiber matrix comprises a plurality of crossing fibers forming a mesh with a plurality of void spaces. The fibers and void spaces are sized and arranged so as to permit passage of fluid through the fiber matrix and to inhibit formation of scar tissue through the fiber matrix. The fibers may comprise a polymeric material, and the fiber matrix may be manufactured by electrospinning. The fibers may comprise a biostable and/or a biodegradable material. In one method of using a fiber matrix, the fiber matrix is positioned under a scleral flap, with at least part of the fiber matrix under the scleral flap. | 12-30-2010 |
| 20100274259 | FLUID DRAINAGE DEVICE, DELIVERY DEVICE, AND ASSOCIATED METHODS OF USE AND MANUFACTURE - The disclosure provides an intraocular implant for allowing fluid flow from the anterior chamber of an eye, the implant comprising a tube having an inlet end, an outlet end, and a tube passage, wherein the inlet end is adapted to extend into the anterior chamber of the eye, and wherein the outlet end is adapted to be implanted adjacent scleral tissue of the eye. The implant may be adapted to drain aqueous humor into a suprachoroidal space or a juxta-uveal space. The disclosure also provides associated delivery devices, methods of use, and methods of manufacture. | 10-28-2010 |
| 20100185138 | FLOW REGULATING IMPLANT, METHOD OF MANUFACTURE, AND DELIVERY DEVICE - An implant includes a tube for permitting fluid flow. A flow controlling rod may be inserted within the tube passage. One or more holes around the circumference of the tube may be selectively permanently or temporarily occluded to give desired flow characteristics. A delivery device for implanting the implant may include a central bore in which a retractable wire is located. The retractable wire penetrates a tube passage of the implant. After the implant is in position in the eye, the retention wire is retracted out of the implant. In a method for manufacturing an implant, two tubes of different diameters are utilized. The smaller tube fits inside the longitudinal bore of the larger tube. When the tubes are cut, the smaller tube forms the tube of the implant and the remaining portions of the larger tube form the retention projection and/or disk of the implant. | 07-22-2010 |
| 20090204053 | DEVICES AND METHODS FOR OPENING FLUID PASSAGEWAYS - Devices and procedures for assisting drainage of aqueous humor from the eye are provided. In accordance with some embodiments, an implant sized to fit within the Schlemm's Canal is provided. The implant has a plurality of penetrating members having an unextended position in which the penetrating members lie generally close to the longitudinal axis of the implant and an extended position in which the penetrating members are extended outward. In use, the implant is advanced around at least a substantial portion of the Schlemm's Canal with the penetrating members in the first unextended position. After the implant is positioned within the Schlemm's Canal, the penetrating members are caused to move from the first unextended position to the second extended position, wherein the penetrating members penetrate the wall of the Schlemm's Canal. This creates fluid passageways in the wall of the Schlemm's Canal. The implant can also serve to keep the Schlemm's Canal open. A delivery device is also provided for implanting an implant into the Schlemm's Canal. | 08-13-2009 |
