Allergan, Inc. - Irvine CA

International Classification:

A61M 3500

US Classification:

604298, 604294, 604289, 604108, 222167

Abstract:

Apparatus for instilling a medicament into an eye includes a housing having a longitudinal axis and a chamber disposed in the housing for containing a medicament. A nozzle is provided for instilling a dose of medicament into an eye and an actuator meters doses of medicament from the chamber to the nozzle and forces each metered dose through the nozzle upon axial displacement of the actuator along housing longitudinal axis. A spring causes the axial displacement of the actuator upon release of the spring from a compressed state. A collar disposed for rotation about the housing longitudinal axis is provided by compressing the spring by twisting the collar about the housing longitudinal axis and a trigger disposed in a housing is provided for releasing the compressed spring.

Assignee:

Glaukos Corporation - Laguna Hills CA

International Classification:

A61M 35/00

US Classification:

604290

Abstract:

The invention relates generally medical devices and methods for the treatment of glaucoma in an animal eye and, more particularly, to medical devices and methods for treating tissue of the trabecular meshwork and/or Schlemm's canal of the eye to restore or rejuvenate a portion or all of the normal physiological function of directing aqueous outflow for maintaining a normal intraocular pressure in the eye.

A61M 31/00

US Classification:

604 8, 604 9, 604 27, 606108

Abstract:

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.

International Classification:

A61M 1/00

US Classification:

606107, 606 5, 606 6

Abstract:

A method is provided for treatment of cataract in combination with a glaucoma procedure while maintaining the intraocular pressure by permitting aqueous to flow out of an anterior chamber of the eye through a surgically stented pathway. A trabecular stent is adapted for implantation within the trabecular meshwork of an eye such that intraocular liquid flows controllably from the anterior chamber of the eye to Schlemm's canal, bypassing the trabecular meshwork. Depending upon the specific treatment contemplated, pharmaceuticals may be utilized in conjunction with the trabecular stent enabling post-cataract healing processes.

US Classification:

604 8, 604521, 604294, 606108, 523 237

Abstract:

The invention relates to methods of treating glaucoma, such as a method that includes inserting a stent through an incision in an eye; the stent having an inflow portion that is in fluid communication with an outflow portion of the stent; transporting the stent from the incision through the anterior chamber of the eye to an aqueous cavity of the eye, such that the inflow portion of the stent is positioned in the anterior chamber and the outflow portion of the stent is positioned at the aqueous cavity; and infusing fluid from the inflow portion to the outflow portion of the stent.

International Classification:

A61F 2/06

US Classification:

623 111, 606108, 128898

Abstract:

Surgical methods and related medical devices for treating glaucoma are disclosed. The method comprises trabecular bypass surgery, which involves bypassing diseased trabecular meshwork with the use of a stent implant. The stent implant is inserted into an opening created in the trabecular meshwork by a piercing member that is slidably advanceable through the lumen of the stent implant for supporting the implant insertion. The stent implant is positioned through the trabecular meshwork so that an inlet end of the stent implant is exposed to the anterior chamber of the eye and an outlet end is positioned into fluid collection channels at about an exterior surface of the trabecular meshwork or up to the level of aqueous veins.
