GLAUCOMA STENT AND METHODS THEREOF FOR GLAUCOMA TREATMENT

摘要

The invention relates generally to medical devices and methods for reducing the intraocular pressure in an animal eye and, more particularly, to stent type devices for permitting aqueous outflow from the eye's anterior chamber and associated methods thereof for the treatment of glaucoma. Some aspects provide a self-trephining glaucoma stent and methods thereof which advantageously allow for a “one-step” procedure in which the incision and placement of the stent are accomplished by a single device and operation. This desirably allows for a faster, safer, and less expensive surgical procedure.

主权项

1. A stent for reducing intraocular pressure by providing outflow of aqueous humor from an anterior chamber of an eye, comprising:
a grommet, wherein the grommet comprises an inlet end, an outlet end, a seat member at the inlet end, a tapered head at the outlet end and a shank member connecting the seat member of the inlet end and the tapered head of the outlet end, wherein the grommet is configured to extend through the trabecular meshwork such that the inlet end resides in the anterior chamber and the outlet end resides in a Schlemm's canal of the eye; and an inner lumen within the grommet, the lumen having an inlet port and an outlet port for providing a flow pathway through the grommet.
