Abstract
Glaucoma treatment can be performed using an intraocular shunt inserter to deliver an intraocular shunt. The shunt can have at least one flow path having an inner diameter of about 50 μm and about 70 μm and between about 170 μm to about 260 μm. The inserter can carry the intraocular shunt within a 27 Gauge needle having a lumen with an inner diameter of between about 220 to about 280 μm. Embodiments of these systems and related procedures can safely and significantly lower glaucoma patient's intraocular pressure and reduce the number of antiglaucoma medications.
Claims20
A system for treating glaucoma, comprising:
- an intraocular shunt made of a cross-linked gelatin, the intraocular shunt having a shunt outer diameter of between about 170 μm to about 260 μm, and the intraocular shunt defining at least one interior flow path having a shunt inner diameter of between about 50 μm and about 70 μm;
- and
- a needle having a lumen to carry the intraocular shunt, the lumen having a lumen inner diameter of between about 220 to about 280 μm.
A method to treat glaucoma, the method comprising:
- advancing a needle through the sclera of the patient to create an opening, wherein the needle has a needle diameter of between about 400 μm to about 420 μm;
- advancing an intraocular shunt through a lumen of the needle and into the opening, wherein the intraocular shunt has a shunt outer diameter of between about 240 to 260 μm and the lumen has a lumen inner diameter of between about 220 μm to about 280 μm for reducing any gap between the shunt and the opening to minimize peritubular flow therebetween, and
- permitting flow through the intraocular shunt, wherein the shunt has a shunt inner diameter of between about 50 μm to about 70 μm.
A system for treating glaucoma, comprising:
- an intraocular shunt made of a cross-linked gelatin, the intraocular shunt having a shunt outer diameter of between about 170 μm to about 260 μm, and the intraocular shunt defining at least one interior flow path having a shunt inner diameter of about 63 μm;
- and
- a needle having a lumen to carry the intraocular shunt, the needle having a needle outer diameter of between about 400 μm to about 420 μm and the lumen having a lumen inner diameter of about 260 μm.
