  • Patent number: 8617094
    Abstract: Methods of treating ocular disorders are disclosed, such as a method that includes inserting an implant in eye tissue, using a delivery 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 delivery 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 following the injection with said fluid remaining within the eye such that the drug has a therapeutic effect on the eye.

  • Publication number: 20130310930
    Abstract: The invention relates generally to medical devices and methods for the treatment of ocular disorders. An ocular implant having an inlet portion with a first anchor and an outlet portion with a second anchor is provided. The first anchor is configured to be positioned adjacent eye tissue, for example, within an anterior chamber of an eye, and the second anchor is configured to be positioned within a physiological outflow pathway of the eye. The implant, when implanted in the eye, is configured to conduct fluid from the anterior chamber to the physiological outflow pathway. Desirably, the second anchor is deployable and is configured to secure the implant within the physiological outflow pathway. Also provided is an ocular treatment method which involves implanting the implant to secure the implant within the physiological outflow pathway by deploying the second anchor.

  • 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.

  • Publication number: 20130253405
    Abstract: Intraocular stents and applicators are disclosed for treating glaucoma. The stents are configured to extend between the anterior chamber of the eye and Schlemm's canal for enhancing outflow of aqueous from the anterior chamber so as to reduce intraocular pressure. The stents can have features for anchoring the stent into Schlemm's canal as well as preventing the walls of Schlemm's canal from closing the outlet of the stents. The applicators can be steerable so as to make implantation easier. Additionally, the applicators can be configured to hold a plurality of stents so that multiple stents can be implanted through one incision without removing the applicator from the incision between serial implantations.

  • Publication number: 20130245532
    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.

  • Publication number: 20120109040
    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: 8075511
    Abstract: Systems and methods for treating ocular disorders are disclosed. One system has an implant and a delivery device. The implant has inlet and outlet portions, a lumen extending therebetween and communicating with inlet and outlet ports. The implant is sized so that in use aqueous humor flows from an anterior chamber of an eye through the implant and into a uveal scleral outflow path of the eye. The delivery device is configured to advance the implant from within the anterior chamber, with the outlet portion leading the inlet portion, to a location where the outlet and inlet ports respectively communicate with the uveal scleral outflow path and the anterior chamber. One method involves advancing an implant from within the anterior chamber, and draining fluid from therein such that fluid flows into an implant inlet port and out through an implant outlet port and into the uveal scleral outflow path.
