Ocular Implants for Delivery Into the Eye
First Claim
1. An ocular implant adapted to reside at least partially in a portion of Schlemm'"'"'s canal of an eye, the implant comprising:
- a spine extending along a longitudinal axis of the implant,a plurality of curved supports extending from the spine, each support comprising a first end extending from a first location on a first side of the spine and a second end extending from a second location on a second side of the spine, the second location being proximal to the first location, so that each support forms a portion of a helix,the spine and supports defining a volume having a maximum width perpendicular to the longitudinal axis between 0.005 inches and 0.04 inches,the ocular implant being configured to bend preferentially in a preferential bending plane.

Abstract
An ocular implant adapted to reside at least partially in a portion of Schlemm'"'"'s canal of an eye. The implant includes a spine extending along a longitudinal axis of the implant, a plurality of curved supports extending from the spine, each support comprising a first end extending from a first location on a first side of the spine and a second end extending from a second location on a second side of the spine, the second location being proximal to the first location, so that each support forms a portion of a helix, the spine and supports defining a volume having a maximum width perpendicular to the longitudinal axis between 0.005 inches and 0.04 inches, the ocular implant being configured to bend preferentially in a preferential bending plane.

18. An ocular implant adapted to reside at least partially in a portion of Schlemm'"'"'s canal of an eye, the implant comprising:
-
a spine extending along a longitudinal axis of the implant, a plurality of supports extending from the spine at a plurality of longitudinally spaced support locations, each support comprising a dorsal loop extending from a first side of the spine and a ventral loop extending from a second side of the spine opposite the first side, and an elongate opening extending along the longitudinal axis and bordered by the spine and the dorsal and ventral loops of the supports, the spine extending continuously through the support locations, the spine and supports defining a volume having a maximum width perpendicular to the longitudinal axis between 0.005 inches and 0.04 inches, the ocular implant being configured to bend preferentially in a preferential bending plane. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method of deploying at least a distal portion of an ocular implant into Schlemm'"'"'s canal of an eye, the eye having a cornea defining an anterior chamber and an iris defining a pupil, the method comprising:
-
advancing a distal portion of a cannula through the cornea so that a curved portion of the cannula is at least partially disposed in the anterior chamber of the eye; advancing a distal tip of the cannula through trabecular meshwork of the eye so that a distal opening of the cannula is placed in fluid communication with Schlemm'"'"'s canal; advancing an ocular implant through the curved portion of the cannula; and rotating the ocular implant as at least a distal portion of the ocular implant is advanced through the distal opening and into Schlemm'"'"'s canal.
