Sclerotomy implant
First Claim
1. A sclerotomy implant intended to enable aqueous humor to flow continuously through a trabeculum, said implant being in the form of a tab made of a biocompatible material, and comprising:
- a trabecular end adapted to be positioned against the trabeculum;
an intra-scleral part, carrying the trabecular end and adapted to be inserted into an opening under a scleral flap;
sub-conjunctival part, extending the intra-scleral part and having a thickness less than that of the intra-scleral part, said sub-conjunctival part adapted to leave the sclera and be positioned under the conjunctiva in contact therewith;
the intra-scleral part and the sub-conjunctival part having lower faces offset so that the lower face of the sub-conjunctival part is recessed in relation to the lower face of the intra-scleral part;
stops situated at the junction between the intra-scleral part and the sub-conjunctival part, and adapted to lock said intra-scleral part in the opening;
an external end, opposite the trabecular end, and carried by the sub-conjunctival part;
flow means, comprising at least one continuous groove extending along the intra-scleral part and the sub-conjunctival part between the trabecular end and the external end, for enabling flow of the aqueous humor from the trabeculum to the conjunctiva; and
wherein the intra-scleral part and the sub-conjunctival part possess upper faces situated substantially in the same plane, and the lower faces are provided with said at least one groove.

Abstract
A sclerotomy implant intended to be set in place in the sclera of the eye in order to provide for a continuous flow of aqueous humor through the trabecula for the treatment of a glaucoma. This implant is configured like a platelet made of biocompatible material and comprising an intrascleral portion (1) and a sub-conjuctival portion (5), the latter being adapted to come out of the sclera and penetrate under the conjunctiva. Retaining flanges (7a, 7b) provide for the blocking of the implant in the trap under the scleral flap. The implant comprises at least one continuous flow passage from its trabecular extremity (2) applied against the trabecula up to its external extremity (6) inserted in the conjunctiva.
