Claims16
A torsion resistant scleral-tensioning stent for positioning in a tunnel formed intrasclerally in a globe of an eye, comprising:
- a generally t-shaped body having a cross portion with a top surface, a bottom surface and a leg portion extending substantially perpendicularly from a side surface of said cross portion;
- said leg portion having a top surface, a bottom surface with an arcuate portion and a substantially planar portion at an end of said leg portion distal from said cross portion;
- wherein said arcuate portion has a radius of curvature from about 8 mm to about 9 mm;
- wherein said top surfaces of said cross portion and said leg portion define a t-shaped configuration;
- and
- wherein said bottom surface of said cross portion is dimensioned to be disposed external to said tunnel for resisting torsional forces on said leg portion.
A scleral-tensioning stent for positioning in a tunnel formed intrasclerally in a globe of an eye, comprising:
- an elongated portion having a top surface and a bottom surface, the bottom surface forming an arc along a portion of a length of the elongated portion;
- a flange, integrally formed with and at a first distal end of the elongated portion and oriented perpendicularly to the elongated portion, having a top surface, a bottom surface and a length wider than a width of the first end of the elongated portion;
- the flange is flat on the bottom surface;
- wherein the bottom surface of a second end of the elongated portion, opposite the first distal end, forms a flat surface;
- and
- wherein said top surfaces of said elongated portion and said flange define a t-shaped configuration.
A torsion resistant scleral-tensioning stent for positioning in a tunnel formed intrasclerally in a globe of an eye, comprising:
- a generally capital t-shaped body having a cross portion with a top surface, a flat bottom surface and a leg portion extending substantially perpendicularly from a side surface of said cross portion;
- said leg portion having a top surface, a bottom surface with an arcuate portion and a substantially planar portion at an end of said leg portion distal from said cross portion;
- wherein said top surfaces of said cross portion and said leg portion define a t-shaped configuration;
- and
- wherein said bottom surface of said cross portion is dimensioned to be disposed external to said tunnel for resisting torsional forces on said leg portion.
A scleral-tensioning stent for positioning in a tunnel formed intrasclerally in a globe of an eye, comprising:
- an elongated portion having a top surface and a bottom surface, the bottom surface forming an arc along a portion of a length of the elongated portion;
- a flange, integrally formed with and at a first end of the elongated portion and oriented perpendicularly to the elongated portion, having a top surface, a bottom surface and a length wider than a width of the first end of the elongated portion to form the shape of a capital T;
- wherein said top surfaces of said elongated portion and said flange define a t-shaped configuration;
- and
- wherein the top surface of the elongated portion is narrower than the bottom surface of the elongated portion.
