1. A device comprising:
- a support having at least one fenestration that is longitudinally insertable into a lumen of Schlemm'"'"'s canal, the support having a cross-sectional dimension sufficient to at least partially prop open Schlemm'"'"'s canal upon insertion into the canal, and to thereby maintain patency of at least a portion of the canal so that fluid may traverse the canal without substantial interference from the support,wherein when the support is disposed within a lumen of Schlemm'"'"'s canal, contact between the support and a wall of the canal is discontinuous along a perimeter of the lumen of the canal, and wherein when the support is disposed within a cylindrical section of the lumen of the canal having an internal wall surface area C, the support contacts less than 30% of C.

Abstract
Devices, methods and kits are described for reducing intraocular pressure. The devices include a support that is implantable within Schlemm'"'"'s canal and maintains the patency of the canal without substantially interfering with transmural fluid flow across the canal. The devices utilize the natural drainage process of the eye and can be implanted with minimal trauma to the eye. Kits include a support and an introducer for implanting the support within Schlemm'"'"'s canal. Methods include implanting a support within Schlemm'"'"'s canal, wherein the support is capable of maintaining the patency of the canal without substantial interference with transmural fluid flow across the canal.

1. A device comprising:
-
a support having at least one fenestration that is longitudinally insertable into a lumen of Schlemm'"'"'s canal, the support having a cross-sectional dimension sufficient to at least partially prop open Schlemm'"'"'s canal upon insertion into the canal, and to thereby maintain patency of at least a portion of the canal so that fluid may traverse the canal without substantial interference from the support, wherein when the support is disposed within a lumen of Schlemm'"'"'s canal, contact between the support and a wall of the canal is discontinuous along a perimeter of the lumen of the canal, and wherein when the support is disposed within a cylindrical section of the lumen of the canal having an internal wall surface area C, the support contacts less than 30% of C. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 29, 30, 31)

32. A device comprising:
-
a support having at least one fenestration that is longitudinally insertable into a lumen of Schlemm'"'"'s canal, the support comprising an exterior surface and having a cross-sectional dimension sufficient to at least partially prop open Schlemm'"'"'s canal upon insertion into the canal, and to thereby maintain patency of at least a portion of the canal so that fluid may traverse the canal without substantial interference from the support, wherein when the support is disposed within a lumen of Schlemm'"'"'s canal, only a portion of the exterior surface of the support contacts an inner periphery of the lumen of the canal, and wherein when the support is disposed within a cylindrical section of the lumen of the canal having an internal wall surface area C, the support contacts less than 30% of C. - View Dependent Claims (33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 60, 61, 62)

- 57. The device of 32, wherein the support comprises an active agent.
-
63. A method for reducing intraocular pressure in an eye, the method comprising:
-
inserting a support having at least one fenestration into a lumen of Schlemm'"'"'s canal to at least partially prop open the canal and thereby maintain patency of at least a portion of the canal, wherein when the support is disposed within the lumen of Schlemm'"'"'s canal, the support allows fluid to traverse the canal without substantial interference from the support, and wherein contact between the support and a wall of the canal is discontinuous along a perimeter of the lumen of the canal, and wherein when the support is disposed within a cylindrical section of the lumen of the canal having an internal wall surface area C, the support contacts less than 30% of C. - View Dependent Claims (64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86)
