1. An ocular implant comprising:
- a longitudinally extending body having an inlet portion and a Schlemm'"'"'s canal portion distal to the inlet portion, the inlet portion, in use, extending into and in fluid communication with an anterior chamber of a human eye;
a plurality of alternating spines and frames positioned longitudinally along at least a portion of the length of the Schlemm'"'"'s canal portion wherein the plurality of alternating spines and frames define a central channel extending therethrough with the central channel in fluid communication with the inlet portion;
each of the spines having edges partially defining one or more openings in fluid communication with the central channel;
each of the frames including first and second struts, the first and second struts each having an edge contiguous with an edge of an adjacent spine and further defining the one or more openings in fluid communication with the central channel, the first and second struts each having a circumferential extent around the central channel greater than a circumferential extent of an adjacent spine.

Abstract
An ocular implant having a first spine; a second spine; a first strut extending in an axial direction Z between the first spine and the second spine; a second strut extending in an axial direction Z between the first spine and the second spine; wherein an angular dimension θ of a first edge of each strut undulates as the strut extends in the axial direction Z between the first spine and the second spine; and wherein a radius r of an outer surface of each strut remains substantially constant as the strut extends the axial direction Z between the first spine and the second spine.

19. An ocular implant comprising:
-
an inlet portion and a Schlemm'"'"'s canal portion distal to the inlet portion, the inlet portion being disposed at a proximal portion of the implant and configured to be placed within an anterior chamber of a human eye, the inlet portion having an inlet adapted to be in fluid communication with the anterior chamber; the Schlemm'"'"'s canal portion having a diameter between 0.005 inches and 0.04 inches with a central channel in fluid communication with the inlet; the Schlemm'"'"'s canal portion further having a first spine extending longitudinally along the central channel and having edges partially defining a first opening in fluid communication with the central channel and a second spine extending longitudinally along the central channel and having edges partially defining the first opening, the second spine being disposed distal to the first spine with a first frame extending longitudinally along the central channel, the first frame being disposed distal to the first spine and proximal to the second spine, the first frame comprising first and second struts, the first and second struts each having a first edge partially defining the first opening, the first edges of the first frame'"'"'s first and second struts each having a circumferential extent around the central channel greater than a circumferential extent of the first spine and a circumferential extent of the second spine, the circumferential extent of the first edges of the first frame'"'"'s first and second struts being less at a distal portion of the struts than at a central portion of the struts; the Schlemm'"'"'s canal portion also including a second frame extending longitudinally along the central channel, the second frame being disposed distal to the second spine, the second frame comprising first and second struts, the second frame'"'"'s first and second struts each having a first edge partially defining the first opening, the first edges of the second frame'"'"'s first and second struts each having a circumferential extent around the central channel greater than the circumferential extent of the first spine and the circumferential extent of the second spine, the circumferential extent of the first edges of the second frame'"'"'s first and second struts being less at a distal portion of the struts than at a central portion of the struts. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
