System and method for treating an ocular disorder
First Claim
1. A method of treating an ocular disorder, comprising:
- providing an ophthalmic drainage implant having a proximal section, a distal section and an internal lumen extending through the implant from at least a portion of the proximal section to at least a portion of the distal section, the ophthalmic drainage implant having a maximum cross-sectional dimension sized to allow insertion of the implant through a corneal opening into the eye to access an anterior chamber of the eye;
providing an elongate delivery member configured for ab interno insertion of the ophthalmic drainage implant and sized to extend across the anterior chamber;
coupling the ophthalmic drainage implant and the elongate delivery member such that a distal end of the elongate delivery member receives at least a portion of the internal lumen of the ophthalmic drainage implant;
advancing the elongate delivery member from an anterior chamber of an eye into a Schlemm'"'"'s canal through ocular tissue to form a drainage pathway from the anterior chamber to the Schlemm'"'"'s canal such that at least a portion of the distal section of the ophthalmic drainage implant extends into and along a portion of the Schlemm'"'"'s canal; and
removing the elongate delivery member from the eye.

Abstract
Surgical methods and related medical devices for treating ocular disorders are disclosed. Some methods relate to delivering an implant within an eye, and involve providing an elongate guide device, such as, a flexible guide member or a guide wire. A distal end of the guide device can be advanced into an anterior chamber of an eye, or through at least a portion of a site of resistance along a physiologic outflow pathway of the eye, or from an anterior chamber of the eye to a location proximate a physiologic outflow pathway of the eye. The implant is advanced along the guide device toward the guide device distal end, and is positioned to conduct aqueous humor between the anterior chamber and the physiologic outflow pathway.

6. A method of treating an ocular disorder, comprising:
-
forming an incision to access an anterior chamber of an eye; penetrating ocular tissue within the eye from within the anterior chamber to form an opening into a Schlemm'"'"'s canal of the eye, thereby forming an aqueous drainage pathway from the anterior chamber to the Schlemm'"'"'s canal; inserting an ocular drainage implant through the opening into the Schlemm'"'"'s canal; and positioning the implant between opposing wall sections of the Schlemm'"'"'s canal so as to increase patency of the aqueous drainage pathway. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A system for treating an ocular disorder in a patient, comprising:
-
a delivery device, said delivery device comprising a handpiece and an elongate delivery member; and an ophthalmic implant comprising a body having a proximal section and a distal section with respect to the handpiece of the delivery device, at least the distal section being curved so as to fit within and extend along a portion of a Schlemm'"'"'s canal of an eye following implantation using the delivery device; wherein the elongate delivery member is configured for ab interno insertion of the ophthalmic implant through a corneal incision and sized to extend across the anterior chamber; and wherein the elongate delivery member is configured to retain the ophthalmic implant therein prior to implantation, and to deliver the ophthalmic implant through a trabecular meshwork of the eye and into and along the portion of the Schlemm'"'"'s canal. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
