Abstract

A glaucoma treatment kit, containing intraocular stents and applicators, is disclosed. The stents are configured to extend between the anterior chamber and Schlemm'"'"'s canal of the eye, for enhancing outflow of aqueous from the anterior chamber so as to reduce intraocular pressure.

Claims

1. A glaucoma treatment kit, comprising:

a sterile package having at least one of (a) plural glaucoma treatment implants and plural applicators for implanting the plural implants in the eye, and (b) plural implants and a single reloadable applicator for implanting the implants in the eye.

2. The glaucoma treatment kit of claim 1, further comprising a cartridge holding at least two of the plural implants of (b).

3. The glaucoma treatment kit of claim 1, wherein the plural glaucoma treatment implants of (a) are held by the respective plural applicators of (a).

4. The glaucoma treatment kit of claim 1, wherein at least one of the plural glaucoma treatment implants comprises:

an outflow portion through which said longitudinal implant axis passes, said outflow portion shaped and sized to be;

(a) introduced into Schlemm'"'"'s canal with said portion of said longitudinal implant axis at an angle to Schlemm'"'"'s canal; and

(b) received within Schlemm'"'"'s canal regardless of a rotational orientation of the outflow portion about said longitudinal implant axis during said introduction; and

an inflow portion configured to permit communication of fluid from the anterior chamber of the eye to the outflow portion.

5. The glaucoma treatment kit of claim 1, wherein at least one of the plural glaucoma treatment implants comprises:

an outflow portion, sized and shaped to be received within Schlemm'"'"'s canal, said outflow portion comprising;

an outflow portion base having an outflow opening; and

at least one standoff member disposed to space said outflow opening from a wall of Schlemm'"'"'s canal, such that said outflow opening is unobstructed by said canal wall.

6. The glaucoma treatment kit of claim 1, wherein at least one of the plural glaucoma treatment implants has a longitudinal implant axis and comprises:

a first portion at a first end of said longitudinal implant axis, said first portion sized and configured to reside in Schlemm'"'"'s canal, such that said first portion has a maximum dimension along a longitudinal axis of Schlemm'"'"'s canal that is not substantially greater than a dimension of the first portion that runs perpendicular to both said longitudinal axis of Schlemm'"'"'s canal and to said longitudinal implant axis; and

a second portion at a second end of said longitudinal implant axis, said second portion configured to provide fluid communication between the anterior chamber and said first portion.

7. The glaucoma treatment kit of claim 1, wherein at least one of the plural glaucoma treatment implants comprises:

an outflow portion, sized and shaped to be received within Schlemm'"'"'s canal;

an inflow portion in fluid communication with said outflow portion, the inflow portion configured to be disposed in the anterior chamber of the eye; and

a central portion extending between the inflow and outflow portions;

the outflow portion having a diameter that is no more than three times the diameter of the central portion.

8. The glaucoma treatment kit of claim 1, wherein at least one of the plural glaucoma treatment implants comprises:

an outflow portion, sized and shaped to be received within Schlemm'"'"'s canal; and

an inflow portion in fluid communication with said outflow portion, the inflow portion configured to be disposed in the anterior chamber of the eye.
