Patent Images
1. An ocular implant, comprising:
- a series of struts forming a series of fenestrations, wherein each of the series of struts comprises an outer convex surface and an inner concave surface that collectively form a generally cylindrical elongate body at least partially surrounding a longitudinal internal volume; and
a fluid ingress region communicating with the internal volume and located near an end portion of the elongate body, wherein the fluid ingress region is adapted to be positioned within an anterior chamber of an eye;
wherein fluid from the anterior chamber flows into the ingress region and out of the internal volume through one or more of the series of fenestrations when the elongate body is positioned in the eye.

Abstract
An ocular implant includes an elongate member having an internal lumen forming a flow pathway that provides a fluid pathway between the anterior chamber and the suprachoroidal space of the eye. The implant includes a hydrogel member attached to the elongate member, wherein the hydrogel member is adapted to expand upon implantation of the elongate member in the eye. An attachment attaches the hydrogel member to the elongate member.

13. An ocular implant, comprising:
-
a body having a proximal end and a distal end, the proximal end comprising an inlet portion adapted to be positioned within an anterior chamber of an eye, wherein the body comprises a generally cylindrical body wall extending between the proximal and distal ends and comprising a plurality of adjacent, non-circular openings spaced along the body providing a flexibility to the body wall, wherein when the implant is implanted in the eye, fluid flowing from the anterior chamber into the implant is able to flow out of the implant through any one of the plurality of adjacent, non-circular openings. - View Dependent Claims (14)
