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 |
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 |
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 |
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 |
20130006164 | 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. | 01-03-2013 |
20130006352 | HEART VALVE REPAIR DEVICES AND METHODS - Devices and methods for the repair of the functioning of heart valves are provided. A device may comprise a first section having a generally spiral shape and a second section connected to the first section. A method involves positioning the device such that chords associated with the heart valve are positioned within the path of the generally spiral shape of the first section and positioning the second section on an opposite side of the heart valve. The first section may be turned in a manner such that the chords move closer to the center of the first section. The first section draws the chords closer together, thereby pulling the valve leaflets closer together in order to facilitate their coaptation and proper closing. | 01-03-2013 |
20140066833 | EXPANDABLE FLUID DRAINAGE IMPLANTS AND ASSOCIATED DELIVERY DEVICES AND METHODS - A drainage implant is provided for the drainage of aqueous humor. The implant may comprise a collector, a connector and disperser. The collector and/or disperser may be self-expandable and can be held in an unexpanded condition by a delivery device. When positioned for implantation, the collector and disperser are ejected from the delivery device, whereby upon being ejected from the delivery device they can expand to a pre-defined final shape in the desired place. A delivery device for implanting the implant may have a shaft for accommodating the implant and a cutting edge that may be used to create a pocket or reservoir in the tissue where the implant device is to be implanted. Methods of implanting an implant are also disclosed. | 03-06-2014 |
20140163669 | DEVICES AND METHODS FOR THE REPLACEMENT OF THE FUNCTIONING OF HEART VALVES - A valve device is provided for implantation at the location of a natural heart valve, for replacing the functioning of the natural heart valve. The valve device includes a holding structure and a plurality of leaflets that open and close as the heart beats and pressure changes. The valve device holding structure may comprise a substantially ring-shaped first section, or ventricular ring, and a substantially ring-shaped second section, or atrial ring, connected together by a connector. The valve device holding structure, which may include all parts besides the leaflets themselves, may be formed from a wire or tube made of a suitable flexible material that allows the valve device to be substantially straightened to a low profile in a constrained delivery condition and that allows the valve device to self-expand to its ring-shaped expanded profile when unconstrained during implantation. | 06-12-2014 |
20150374493 | HEART VALVE REPAIR DEVICES FOR PLACEMENT IN VENTRICLE AND DELIVERY SYSTEMS FOR IMPLANTING HEART VALVE REPAIR DEVICES - Devices and methods for the repair of the functioning of heart valves are provided. A device may comprise a ventricular winding having a generally spiral shape, wherein the device is free of any atrial stabilizing section. A method involves positioning the device such that chords associated with the heart valve are positioned within the path of the generally spiral shape of the ventricular winding and turning the ventricular winding such that the chords move closer to the center of the ventricular winding. The ventricular winding draws the chords closer together, thereby pulling the valve leaflets closer together in order to facilitate their coaptation and proper closing. A delivery system for maneuvering and releasing a heart valve repair device comprises an applicator tube and internal rod. | 12-31-2015 |
