1. An ocular implant, comprising:
- an elongate member having a flow pathway, at least one inflow port communicating with the flow pathway, and an outflow port communicating with the flow pathway, wherein the elongate member includes a first distal portion including a spring-loaded braided structure configured to form a first length and a first outer diameter when in tension and form a second length and a second outer diameter upon release of tension, wherein the first length is longer than the second length and the first outer diameter is smaller than the second outer diameter, the braided structure including a distal end secured by a solid bullet-nose structure, and a second portion formed at least partially of a non-braided structure, wherein the entire second portion is positioned proximal of the first portion along a longitudinal axis of the elongate member, the elongate member is configured to be implanted through a self-sealing corneal incision and positioned in the eye such that the inflow port communicates with the anterior chamber and the outflow port communicates with the suprachoroidal space.

Abstract
Disclosed are devices, methods and systems for treatment of eye disease such as glaucoma. Implants are described herein that enhance aqueous flow through the normal outflow system of the eye with minimal to no complications. The implant can be reversibly deformed to a first shape, such as a generally linear shape conducive to insertion. Upon insertion, the implant can deform to a second shape, such as a generally non-linear shape conducive to retention within the eye. The shape also improves fluid flow from the anterior chamber and prevents or reduces clogging.

7. A system for treating an ocular disorder in a patient, comprising:
-
an elongate member having a flow pathway, at least one inflow port communicating with the flow pathway, and an outflow port communicating with the flow pathway, wherein the elongate member includes a first distal portion including a spring-loaded braided structure configured to form a first length and a first outer diameter when in tension and form a second length and a second outer diameter upon release of tension, wherein the first length is longer than the second length and the first outer diameter is smaller than the second outer diameter, the braided structure including a distal end secured by a solid bullet-nose structure, and a second portion formed at least partially of a non-braided structure, wherein the entire second portion is positioned proximal of the first portion along a longitudinal axis of the elongate member, wherein the elongate member is configured to be implanted through a self-sealing corneal incision and positioned in the eye such that the inflow port communicates with the anterior chamber and the outflow port communicates with the suprachoroidal space; and a delivery device having a delivery component that removably attaches to the elongate member, wherein the delivery component is configured to secure the elongate member in tension during implantation of the elongate member. - View Dependent Claims (8, 9, 10, 11, 12, 13)
