  • Publication number: 20130245600
    Abstract: Drug formulations, devices and methods are provided to deliver biologically active substances to the eye. The formulations are delivered into scleral tissues adjacent to or into the suprachoroidal space without damage to the underlying choroid. One class of formulations is provided wherein the formulation is localized in the suprachoroidal space near the region into which it is administered. Another class of formulations is provided wherein the formulation can migrate to another region of the suprachoroidal space, thus allowing an injection in the anterior region of the eye in order to treat the posterior region.

  • Publication number: 20120191064
    Abstract: Devices and methods are provided for access to the sub-retinal space that lies between the retina and the choroid in order to introduce therapies to the retina and more specifically to the sensory retina and RPE, particularly in the region of the macula. The devices comprise a catheter that incorporates advantageous size, flexibility and tip features to properly, accurately and atraumatically access the sub-retinal space. Ancillary devices to assist in placing catheters into the sub-retinal space are also provided. The catheter devices incorporate a lumen for delivery of therapeutic substances or devices into the eye.

  • Publication number: 20100173866
    Abstract: The invention provides tools, materials and related methods to surgically access the suprachoroidal space of an eye for the purpose of performing minimally invasive surgery or to deliver drugs to the eye. The invention provides a flexible microcannula or microcatheter device (11, 13) that may be placed into the suprachoroidal space (12, 14) through a small incision (12A) of the overlying tissues, maneuvered into the appropriate region of the space, and then activated to treat tissues adjacent to the distal tip of the device.

  • Publication number: 20090297567
    Abstract: A method is provided for site specific delivering therapeutic or diagnostic agents to a region in a fluid-filled cavity, vessel or tissue using an agent-loaded microbubble population. The population has controlled fragility characterized by a uniform wall thickness to diameter ratio which defines the discrete threshold intensity value of ultrasonic power where microbubble rupture occurs in the population. The location of the microbubble population may be monitored by ultrasound to determine its presence at the region prior to application of the ultrasonic power to rupture to microbubbles.

  • Publication number: 20090043321
    Abstract: An apparatus is provided for forming a tissue tract (8, 11A, 17A) from within a first passageway of an eye (11, 17) connecting to a second passageway in the eye (12, 16) comprising an elongated tool with a proximal end and distal end. The tool has an outer diameter in the range of about 50 to about 1000 microns.

  • Patent number: 7229440
    Abstract: Devices and methods for a minimally invasive procedure for cutting tissue are disclosed. The device generally includes a probe with a distal exit at an exit angle relative to the probe, a cutting loop with shape memory having a preconfigured shape, and a loop securing mechanism to secure the cutting loop in a penetrating configuration and to release the cutting loop into a cutting configuration. The cutting loop is generally within a profile of the probe in the penetrating configuration. In the cutting configuration, the cutting loop extends through the cutting loop exit and generally returns to the preconfigured shape at a cutting angle generally defined by the exit angle. The cutting loop securing mechanism may be, for example, a cover slidable over the probe, a slidable member extending from a distal tip of the probe, or a groove defined in the probe proximal to the cutting loop exit.

  • Publication number: 20060195187
    Abstract: An implant is placed within Schlemm's canal of the eye and provides tension to the trabecular meshwork. The tension is continuous and increases the aqueous outflow without the necessity of administering cholinergic drugs to treat glaucoma.

  • Publication number: 20060155300
    Abstract: The invention provides minimally invasive microsurgical tools and methods to form an aqueous humor shunt or bypass for the treatment of glaucoma. The invention enables surgical creation of a tissue tract (7) within the tissues of the eye to directly connect a source of aqueous humor such as the anterior chamber (1), to an ocular vein (4). The tissue tract (7) from the vein (4) may be connected to any source of aqueous humor, including the anterior chamber (1), an aqueous collector channel, Schlemm's canal (2), or a drainage bleb. Since the aqueous humor passes directly into the venous system, the normal drainage process for aqueous humor is restored. Furthermore, the invention discloses devices and materials that can be implanted in the tissue tract to maintain the tissue space and fluid flow.

  • Publication number: 20060149194
    Abstract: An ophthalmic microsurgical system is described for treatment of eye diseases, such as glaucoma, using minimally invasive surgical techniques. The microsurgical system includes a thin walled outer sheath microcannula 1 slidably disposed about an inner member 4, which extends slightly beyond the distal end of the microcannula 1. The inner member 4 may be straight or curved and may optionally include a surgical instrument and/or a sensor or signaling beacon. The microsurgical system is used in a surgical procedure for opening Schlemm's Canal to provide drainage of aqueous fluid in order to relieve excess intraocular that results from glaucoma an other diseases of the eye.
