Abstract
An intravitreous stent includes a multi-loop single wire having a proximal end; a distal end; at least a first loop defined by the proximal end and a first portion of the single wire; at least a second loop defined by the distal end and a second portion of the single wire; wherein the first portion is joined to the second portion via a reversing loop portion.
Claims21
An intravitreous stent comprising:
- a multi-loop single wire comprising:
- a proximal end;
- a distal end;
- at least a first loop defined by the proximal end and a first portion of the single wire;
- at least a second loop defined by the distal end and a second portion of the single wire, wherein the second loop comprises a sinusoidal wave configured to perpendicularly contact a retina of an eye, such that one or more zenith points or nadir points of the sinusoidal wave are configured to contact the retina;
- wherein:
- the first portion is joined to the second portion via a reversing loop portion;
- the second loop has a diameter that is larger than that of the first loop;
- and
- the intravitreous stent is self adaptive to a dimension of a vitreous cavity in an eye;
- and wherein the stent is configured to be straightened prior to or during insertion in the eye.

A method for securing a natural or synthetic intraocular lens in an eye, the method comprising:
- inserting a cannula through an anterior portion of an eye;
- feeding an intravitreous stent through the cannula and into the eye;
- and
- contacting a natural or synthetic intraocular lens with the intravitreous stent to fix a position of the lens within the eye;
- wherein:
- the intravitreous stent comprises:
- a multi-loop single wire comprising:
- a proximal end;
- a distal end;
- at least a first loop defined by the proximal end and a first portion of the single wire;
- at least a second loop defined by the distal end and a second portion of the single wire, wherein the second loop comprises a sinusoidal wave configured to perpendicularly contact a retina of an eye, such that one or more zenith points or nadir points of the sinusoidal wave are configured to contact the retina;
- and
- wherein:
- the first portion is joined to the second portion via a reversing loop portion;
- the second loop has a diameter that is larger than that of the first loop;
- and
- the intravitreous stent is self adaptive to a dimension of a vitreous cavity in an eye;
- and wherein the stent is configured to be straightened prior to or during insertion in the eye.
