Ocular implant with double anchor mechanism
First Claim
1. A method of treating an ocular disorder, comprising:
- providing an implant comprising an inlet portion having a first anchor and an outlet portion having a second anchor;
introducing the implant into an anterior chamber of an eye such that at least the second anchor of the implant is temporarily in the anterior chamber; and
implanting the implant in tissue of the eye such that the implant conducts fluid from the anterior chamber of the eye to a physiological outflow pathway of the eye, said implanting comprising;
positioning the first anchor adjacent eye tissue;
positioning the second anchor within the physiological outflow pathway; and
deploying the second anchor so that the second anchor changes from a first shape to a second shape such that the second anchor in the second shape secures the implant within the physiological outflow pathway and a distal end of the second anchor is positioned farther into the physiological outflow pathway than an outlet of the outlet portion;
wherein the implant has a longitudinal axis extending therethrough and terminating at a distal-most end of the implant wherefrom extends a generally transverse and continuous distal surface of the implant, and wherein when deployed a part of the second anchor contacts a sclera of the eye such that said part of the second anchor is disposed intermediate the distal surface of the implant and a proximal end of the second anchor.

Abstract
The invention relates generally to medical devices and methods for the treatment of ocular disorders. One method provides an implant having an inlet portion with a first anchor and an outlet portion with a second anchor. The implant is implanted in tissue of an eye such the implant conducts fluid from an anterior chamber of the eye to a physiological outflow pathway of the eye. The implanting involves positioning the first anchor adjacent eye tissue, positioning the second anchor within the physiological outflow pathway, and deploying the second anchor such that the second anchor secures the implant within the physiological outflow pathway and a distal end of the second anchor is positioned further into the physiological outflow pathway than an outlet of the outlet portion.
