  • Patent number: 9220632
    Abstract: Methods of treating ocular disorders are disclosed, including: inserting an implant in eye tissue, using an instrument, such that an inlet portion of the implant is in an anterior chamber of an eye and an outlet portion of the implant is in a physiological outflow pathway; removing the instrument from the eye without removing the implant; and conducting fluid comprising a therapeutic substance through the implant and into the physiological outflow pathway. Another method includes inserting an instrument into a physiologic outflow pathway through which aqueous humor drains from an anterior chamber of an eye; separating first and second walls of tissues which comprise the physiologic outflow pathway by injecting a fluid comprising a drug from the instrument while the instrument remains in the physiologic outflow pathway; and withdrawing the instrument with said fluid remaining within the eye such that the drug has a therapeutic effect on the eye.

  • Publication number: 20150223981
    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.

  • Patent number: 8579846
    Abstract: Implants and methods for treating ocular disorders are disclosed. One implant has a tubular member, with inlet and outlet ends, and a cutting member connected thereto. The tubular member is configured to extend through eye tissue such that the inlet and outlet ends reside respectively in an anterior chamber and a physiologic outflow pathway of the eye. Desirably, the cutting member is configured to make an incision in the eye tissue for receiving at least a portion of the tubular member. One method involves introducing an implant, with proximal and distal ends, into the anterior chamber and penetrating eye tissue using an implant distal portion. The implant is advanced from the anterior chamber into the penetrated eye tissue to locate the distal and proximal ends respectively in the physiologic outflow pathway and the anterior chamber. Aqueous humor is conducted between the proximal and distal ends.

  • Patent number: 8348877
    Abstract: Implants and methods for treating ocular disorders are provided. One method involves introducing an implant into an anterior chamber of an eye such that at least a distal end of the implant is temporarily in the anterior chamber. The implant is implanted into eye tissue adjacent the anterior chamber. A therapeutic agent is eluted from the implant into at least one of the anterior chamber, a physiologic outflow pathway of the eye, and a space adjacent a choroid of the eye. The therapeutic agent can be an antiproliferative agent, an anti-inflammatory drug, or a compound for treating glaucoma or ocular hypertension. The therapeutic agent can be contained within the implant or coated on the implant.
