Abstract
An ocular implant adapted to be disposed within Schlemm's canal of a human eye with a body extending along a curved longitudinal central axis in a curvature plane, a first strut on one side of the implant and a second strut on an opposite side of the implant, the circumferential extent of the first strut with respect to the plane of curvature being greater than the circumferential extent of the second strut with respect to the plane of curvature. The invention also includes methods of using the implant.
Claims14
An ocular implant adapted to be disposed within Schlemm's canal of a human eye and configured to support Schlemm's canal in an open state, the ocular implant comprising:
- a body extending along a curved longitudinal central axis and configured to bend in a curvature plane, the body comprising a central channel, first and second frames and a spine interposed between the first and second frames, wherein the spine extends circumferentially from one side of the curvature plane and from an opposite side of the curvature plane, the body having dimensions adapted to be fit within Schlemm's canal;
- each frame comprising a first strut extending circumferentially on the one side of the curvature plane and a second strut extending circumferentially on the opposite side of the curvature plane, the first strut extending further out of the curvature plane than the corresponding second strut such that the first and second frames are not symmetric about the curvature plane.
An ocular implant adapted to be disposed within Schlemm's canal of a human eye and configured to support Schlemm's canal in an open state, the ocular implant comprising:
- a body extending along a curved longitudinal central axis and configured to bend in a curvature plane, the body comprising a central channel, first and second frames and a spine interposed between the first and second frames, wherein the spine extends circumferentially from one side of the curvature plane and from an opposite side of the curvature plane, the body having dimensions adapted to be fit within Schlemm's canal;
- each frame comprising a first strut extending circumferentially on the one side of the curvature plane to a first landing surface and a second strut extending circumferentially on the opposite side of the curvature plane to a second landing surface, a footprint line drawn between the first landing surface and the second landing surface of each of the first frame and the second frame defining a roll angle with respect to the curvature plane of other than 90 degrees.
