  • Ocular filtration devices, systems and methods
    Patent number: 10238536
    Abstract: A glaucoma drainage device regulator (GDDR) is disclosed which comprises a membrane and a lumen to regulate the flow of aqueous in conjunction with different ocular (e.g., glaucoma) filtering procedures. In connection with aqueous shunting, the GDDR can be placed over the tip of a shunt tube in the anterior chamber, either at the time of initial surgery or also in devices which have been previously implanted. In connection with trabeculectomy, the GDDR can comprise a flange for seating the GDDR at the sclerostomy in trabeculectomy surgery.
    Type: Grant

  • OCULAR FILTRATION DEVICES, SYSTEMS AND METHODS
    Publication number: 20180036173
    Abstract: A glaucoma drainage device regulator (GDDR) is disclosed which comprises a membrane and a shunt tube to regulate the flow of aqueous in conjunction with different ocular (e.g., glaucoma) filtering procedures. In connection with aqueous shunting, the membrane of the shunt tube of the GDDR can be placed in the anterior chamber of the eye during implantation and coupled to a reservoir. The GDDR is implanted in a manner to permit easy access to the membrane for post surgery perforation of the membrane to regulate the aqueous flow of the shunt tube.
