OCULAR IMPLANT SYSTEM AND METHOD

摘要

An ocular implant and delivery system having a channel tool adapted to extend through at least a portion of Schlemm's canal of a human eye and to determine whether the Schlemm's canal portion provides a suitable location for the delivery of an ocular implant; an ocular implant adapted to be disposed within Schlemm's canal of a human eye; and a cannula comprising a distal opening adapted to deliver the channel tool and the ocular implant into Schlemm's canal of the eye. The invention also provides a method of treating glaucoma in a human eye including the steps of inserting a distal exit port of a cannula at least partially into Schlemm's canal of the eye; delivering a channel tool through the cannula into Schlemm's canal; delivering an ocular implant through the cannula into Schlemm's canal; and removing the channel tool and the cannula from the eye while leaving the ocular implant in place within Schlemm's canal.
