  • Patent number: 8486052
    Abstract: A delivery device that allows for the sustained release of an agent, particularly useful for the sustained release of a therapeutic agent to limited access regions, such as the posterior chamber of the eye and inner ear. The delivery device is minimally invasive, refillable and may be easily fixed to the treatment area. The delivery device includes a hollow body with an inlet port at its proximal end for insertion of the agent, a reservoir for holding the agent and a delivery mechanism for the sustained delivery of the agent from the reservoir to the patient.

  • Patent number: 8454582
    Abstract: Featured is a method for instilling one or more bioactive agents into ocular tissue within an eye of a patient for the treatment of an ocular condition, the method comprising concurrently using at least two of the following bioactive agent delivery methods (A)-(C): (A) implanting a sustained release delivery device comprising one or more bioactive agents in a posterior region of the eye so that it delivers the one or more bioactive agents into the vitreous humor of the eye; (B) instilling (e.g., injecting or implanting) one or more bioactive agents subretinally; and (C) instilling (e.g., injecting or delivering by ocular iontophoresis) one or more bioactive agents into the vitreous humor of the eye.

  • Patent number: 8365721
    Abstract: A method for performing intraocular brachytherapy and an apparatus for performing the same is disclosed. The apparatus preferably comprises a hand-held delivery device that advances a radiation source into an associated cannula or probe that is positioned adjacent the target tissue. The handpiece provides for shielded storage of the radiation source when retracted from the cannula and includes a slider mechanism for advancing and retracting the radiation source. The radiation source is mounted to a wire that has a flexible distal end and a relatively stiffer proximal end. A positioning system for the cannula is also disclosed.

  • Patent number: 7485113
    Abstract: Devices and devices for the treatment of the eye are disclosed. Preferred devices of the invention include a piercing member that is inserted into the eye to create a pathway for a cannula. The cannula is slidably mounted to the piercing member and is adapted to reach a treatment site within the eye at which material is injected into and/or withdrawn from the eye. The outer diameter of the piercing member is small enough to allow for self-sealing of the insertion site of the device upon the device's withdrawal therefrom. Also disclosed are methods for the utilizing the devices to treat the eye.

  • Patent number: 7217263
    Abstract: A microcatheter system that allows for vascular infusion into retinal veins for extended periods of time. The microcatheter system includes a flexible cannula that is inserted into the retinal vein lumen and that remains stably within the retinal vein lumen without being held by a robot, micromanipulator or similar holding devices. The microcatheter system is particularly suitable for the treatment of retinal venous occlusive disease.
