  • Publication number: 20160045363
    Abstract: Disclosed herein are drug delivery devices and methods for the treatment of ocular disorders requiring targeted and controlled administration of a drug to an interior portion of the eye for reduction or prevention of symptoms of the disorder. The devices are capable of controlled release of one or more, drugs and may also Include structures which allow for treatment permitting aqueous humor to flow out of the anterior chamber of the eye through the device.

  • Publication number: 20160038338
    Abstract: Delivery devices, systems and methods are provided for inserting an implant into an eye. The delivery or inserter devices or systems can be used to dispose or implant an ocular stent or implant, such as a shunt, in communication with a suprachoroidal space of the eye. The implant can drain fluid from an anterior chamber of the eye to a physiologic outflow path of the eye, such as, the suprachoroidal space or other portion of the uveoscleral outflow path. The delivery or inserter devices or systems can be used in conjunction with other ocular surgery, for example, but not limited to, cataract surgery-through a preformed corneal incision, or independently with the inserter configured to make a corneal incision. The implant can be preloaded with or within the in serter to advantageously provide a sterile, easy-to-use package for use by an operator.

  • Patent number: 9066782
    Abstract: Implants and methods for treating ocular disorders are provided. One method involves introducing an implant into an anterior chamber of an eye. The implant is implanted into eye tissue adjacent the anterior chamber such that a proximal end of the implant resides in the anterior chamber following implantation. A therapeutic agent is eluted from the implant into the eye. Desirably, the release of the therapeutic agent from the implant is controlled. The controlled release of the therapeutic agent can be at a chosen rate and/or for a selected duration which can be episodic or periodic. The therapeutic agent can be an antiproliferative agent, an anti-inflammatory drug, or a compound for treating glaucoma or ocular hypertension.

  • Patent number: 9044102
    Abstract: A bedding or seating product comprising a spring core including upper and lower border wires. Each of the border wires is generally rectangular in cross-section to reduce wire costs without compromising beam strength of the border wire. Each row of springs of the spring core may be made of a single piece of wire. The rows of springs may be arranged in side-by-side rows and columns and be connected with each other by helical lacing wires.

  • Publication number: 20150065940
    Abstract: Delivery devices, systems and methods are provided for inserting an implant into an eye. The delivery or inserter devices or systems can be used to dispose or implant an ocular stent or implant, such as a shunt, in communication with the suprachoroidal space, uveal scleral outflow pathway, uveoscleral outflow path or supraciliary space of the eye. The implant can drain fluid from an anterior chamber of the eye to a physiologic outflow path of the eye, such as, the suprachoroidal space, uveal scleral outflow pathway, uveoscleral outflow path or supraciliary space. Alternatively, or in addition, the implant can elute a drug or therapeutic agent. The delivery or inserter devices or systems can be used in conjunction with other ocular surgery, for example, but not limited to, cataract surgery through a preformed corneal incision, or independently with the inserter configured to make a corneal incision.

  • Publication number: 20140343475
    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.
