Abstract
An apparatus is provided for forming a tissue tract (8, 11A, 17A) from within a first passageway of an eye (11, 17) connecting to a second passageway in the eye (12, 16) comprising an elongated tool with a proximal end and distal end. The tool has an outer diameter in the range of about 50 to about 1000 microns. Methods of using the tool are provided for creating a fluid path for aqueous humor of an eye from a first passageway of the eye, such as the Schlemm'"'"'s Canal, to a second passageway, such as the suprachoroidal space

32. A method for creating a fluid path for aqueous humor of an eye from a first passageway of the eye comprising Schlemm'"'"'s Canal to a second passageway comprising the suprachoroidal space, the method comprising:
-
a) inserting a microsurgical tool from a surgical access site into said first passageway; b) advancing said tool along said first passageway to a desired site for formation of a tissue tract for said fluid path; c) actuating said tool to form said tissue tract from said first passageway to said second passageway; d) removing said tool and e) closing said surgical access site. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40)

33. A method for creating a fluid path for aqueous humor of an eye from a first passageway of the eye comprising the suprachoroidal space to a second passageway selected from Schlemm'"'"'s Canal or the anterior chamber, the method comprising:
-
a) inserting a microsurgical tool from a surgical access site into said first passageway; b) advancing said tool along said first passageway to a desired site for formation of a tissue tract for said fluid path; c) actuating said tool to form said tissue tract from said first passageway to said second passageway; d) removing said tool and e) closing said surgical access site.
