Fluid infusion methods for glaucoma treatment
First Claim
1. A method of treating an ocular disorder, comprising:
- using a delivery instrument to insert an implant in eye tissue such that an inlet portion of the implant is in an anterior chamber of an eye and an outlet portion of the implant is in a physiologic outflow pathway so as to conduct aqueous humor from the anterior chamber to the physiologic outflow pathway through the implant;
removing the delivery instrument from the eye without removing the implant; and
providing a fluid comprising a therapeutic substance into the anterior chamber so as to conduct the fluid comprising the therapeutic substance through the implant and into the physiologic outflow pathway such that the therapeutic substance has a pharmacological effect on the eye.

Abstract
Methods of treating ocular disorders are disclosed, such as a method that includes inserting an implant in eye tissue, using a delivery instrument, such that an inlet portion of the implant is in an anterior chamber of an eye and an outlet portion of the implant is in a physiological outflow pathway; removing the delivery instrument from the eye without removing the implant; and conducting fluid comprising a therapeutic substance through the implant and into the physiological outflow pathway. Another method includes inserting an instrument into a physiologic outflow pathway through which aqueous humor drains from an anterior chamber of an eye; separating first and second walls of tissues which comprise the physiologic outflow pathway by injecting a fluid comprising a drug from the instrument while the instrument remains in the physiologic outflow pathway; and withdrawing the instrument following the injection with said fluid remaining within the eye such that the drug has a therapeutic effect on the eye.

14. A method of treating an ocular disorder, comprising:
-
inserting an implant through an incision in an eye; positioning the implant in the eye such that an inlet portion of the implant is in an anterior chamber of the eye and an outlet portion of the implant is in a physiologic outflow pathway with the inlet and outlet portions being in fluid communication so as to conduct aqueous humor from the anterior chamber to the physiologic outflow pathway through the implant; providing a delivery lumen such that the delivery lumen is in fluid communication with the implant; and infusing a fluid external to the eye through the delivery lumen into the anterior chamber such that the fluid flows from the inlet portion of the implant to the outlet portion of the implant and into the physiologic outflow pathway so that the fluid has a pharmacological effect on the eye. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)

26. A method of treating an ocular disorder, comprising:
-
inserting an instrument into an anterior chamber of an eye; advancing the instrument through eye tissue separating the anterior chamber from a physiologic outflow pathway through which aqueous humor drains from the anterior chamber and inserting the instrument into the physiologic outflow pathway; separating first and second walls of tissues which comprise the physiologic outflow pathway by injecting a fluid comprising a drug from the instrument while the instrument remains in the physiologic outflow pathway; disposing an implant between the first and second walls of tissues with at least a portion of the implant extending into and through a section of the physiologic outflow pathway; and withdrawing the instrument following the placement of the implant in the eye and with said fluid remaining within the eye such that the drug has a pharmacological effect on the eye. - View Dependent Claims (27, 28, 29, 30, 31)
