Ocular implant architectures
First Claim
1. 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 end of the implant and sized 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, the Schlemm'"'"'s canal portion comprising:
- a central channel in fluid communication with the inlet, the central channel extending longitudinally in a Z direction;
a first spine disposed along the central channel and having edges partially defining a first opening in fluid communication with the central channel;
a second spine disposed along the central channel and having edges partially defining the first opening, the second spine being disposed distal to the first spine;
a first frame disposed along the central channel distal to the first spine and proximal to the second spine;
a second frame disposed along the central channel distal to the second spine;
the first and second frames each 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 and second struts each having a circumferential extent around the central channel that undulates as the strut extends in the Z direction;
the spines and frames being arranged and configured to be disposed within Schlemm'"'"'s canal of the eye when the inlet is disposed in the anterior chamber.

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.
