US 2013/0211312 A1 · Prefilled Ocular Implants and Methods

Abstract

A drainage device for implantation in an eye of a patient to treat an ocular condition includes a first tube configured to extend into an anterior chamber of the eye and convey aqueous humor from the anterior chamber. An exit portion is in fluid communication with the distal end portion. A passage extends between the distal portion of the first tube and the exit portion, with a liquid disposed in the passage. The implant may include a first seal associated with the distal end portion and a second seal associated with the exit portion to prevent drainage of the liquid through the exit portion. The implant may include an implant body disposed between the distal end portion and the exit portion, the passage extending through the implant body. The implant body may comprise a fluid-sensitive component in fluid communication with the passage that may be formed of a flexible membrane.

Dependent claims

A drainage device for implantation in an eye of a patient to treat an ocular condition, the drainage device comprising:

a drainage first tube having a distal end portion and being configured to extend into an anterior chamber of the eye and convey aqueous humor from the anterior chamber;
an exit portion disposed in fluid communication with the distal end portion of the drainage tube, the exit portion being disposed relative to the distal end portion to drain the aqueous humor to a drainage site in or around the eye;
a passage extending between the distal portion of the drainage tube and the exit portion;
an implant body disposed between the distal end portion and the exit portion, the passage extending through the implant body, the implant body comprising a fluid sensitive component;
a liquid disposed in the passage, the liquid in contact with the fluid sensitive component to preserve the fluid sensitive component;
a first seal associated with the distal end portion disposed to prevent drainage of the liquid through the hollow lumen;
and
a second seal associated with the exit portion disposed to prevent drainage of the liquid through the exit portion.

5 more elements

A method of manufacturing a drainage device for implantation in an eye of a patient to treat an ocular condition, the method comprising:

providing a plate portion sized and configured to be disposed along a globe of the eye of the patient, the plate portion comprising an inlet, an outlet, and a passage extending between the inlet and the outlet, the plate portion comprising a fluid sensitive component disposed adjacent to the passage;
associating a drainage tube with the inlet, of the plate portion to place a hollow lumen of the drainage tube in fluid communication with the passage of the plate portion, the hollow lumen being sized to convey aqueous humor from the anterior chamber to the plate portion;
introducing a liquid into the plate portion in communication with the fluid sensitive component;
preserving the fluid sensitive component with the liquid;
cooperatively associating a first seal with the inlet of the plate portion to prevent the liquid from draining from the plate portion through the inlet;
and
cooperatively associating a second seal with the outlet of the plate portion to prevent the liquid from draining from the plate portion through the outlet.
