  • Patent number: 8529494
    Abstract: An ocular implant for treating glaucoma is provided, which may include any number of features. More particularly, the present invention relates to implants that facilitate the transfer of fluid from within one area of the eye to another area of the eye. One feature of the implant is that it includes a proximal inlet portion and a distal inlet portion adapted to be inserted into the anterior chamber of the eye, and an intermediate portion adapted to be inserted into Schlemm's canal. Another feature of the implant is that it can be biased to assume a predetermined shape to aid in placement within the eye.

  • Patent number: 8512404
    Abstract: A method of inserting an ocular implant into a patient's eye, the ocular implant being mounted on a carrier, the method comprising: inserting a cannula into an anterior chamber of the eye; moving a distal exit port of the cannula into communication with Schlemm's canal; and advancing the ocular implant and carrier through an exit port of the cannula into Schlemm's canal. The invention also provides an ocular implant and delivery system comprising: a cannula comprising a distal exit port adapted to be inserted into a Schlemm's canal portion of an eye; an ocular implant; a carrier disposed within the implant and movable with the implant within the cannula; and a proximal control adapted to be operated from exterior to an eye to move at least one of the carrier and the implant when the distal exit port of the cannula is within the eye.

  • Patent number: 8425449
    Abstract: An ocular implant is provided. In some embodiments, the ocular implant includes a body that is curved about a longitudinal central axis and a distal body portion that defines a longitudinal channel including a channel opening. The implant is sized and configured such that the ocular implant assumes an orientation in which the channel opening is adjacent a major side of Schlemm's canal when the ocular implant is disposed in Schlemm's canal. Methods for delivering ocular implants into Schlemm's canal are also provided. Some methods include covering openings in the ocular implant, advancing the implant into Schlemm's canal while at least some of the openings are covered, and uncovering the openings while the distal portion of the implant is disposed in Schlemm's canal.

  • Patent number: 8414518
    Abstract: An ocular implant adapted to reside at least partially in a portion of Schlemm's canal of an eye. In some embodiments the implant has a body extending in a curved volume whose longitudinal axis forms an arc of a circle, and a plurality of open areas and strut areas formed in the body, the open areas extending over more than 50% of a surface defining the curved volume, the strut areas surrounding the open areas, the body having a diameter of between 0.005 inches and 0.04 inches. The invention also provides a method of treating glaucoma including the steps of supporting tissue forming Schlemm's canal in an eye with an implant extending at least partially in the canal along an axial length within the canal; and contacting with the implant less than 50% of the tissue forming the canal along the axial length.

  • Patent number: 8372026
    Abstract: An ocular implant having a first spine; a second spine; a first strut extending in an axial direction Z between the first spine and the second spine; a second strut extending in an axial direction Z between the first spine and the second spine; wherein an angular dimension ? of a first edge of each strut undulates as the strut extends in the axial direction Z between the first spine and the second spine; and wherein a radius r of an outer surface of each strut remains substantially constant as the strut extends the axial direction Z between the first spine and the second spine.

  • Patent number: 8337509
    Abstract: A cannula for an ocular implant delivery system. In some embodiments, the cannula includes a tubular member having a curved portion, a distal opening surrounded by a distal opening surface, and a distal tip, the distal tip being adapted to be inserted into an anterior chamber of a human subject's eye, through trabecular meshwork and into Schlemm's canal of the eye, a proximal portion of the tubular member being adapted to extend from a location exterior to the eye when the distal tip is in Schlemm's canal of the eye, the cannula being further adapted to cooperate with an advancement mechanism to advance an ocular implant through the tubular member toward and through the distal opening into Schlemm's canal of the eye when the distal tip is disposed in Schlemm's canal.
