    摘要: A visual prosthesis comprises a camera for perceiving a visual image and generating a visual signal output, retinal tissue stimulation circuitry adapted to be operatively attached to the user's retina, and wireless communication circuitry for transmitting the visual signal output to the retinal tissue stimulation circuitry within the eye. To generate the visual signal output the camera converts a visual image to electrical impulses which are sampled to selecting an image at a given point in time. The sampled image signal is then encoded to allow a pixelized display of it. This signal then is used to modulate a radio frequency carrier signal. A tuned coil pair having a primary and a secondary coil are used to transmit and receive the RF modulated visual signal which is then demodulated within the eye. The retinal stimulation circuitry includes a decoder for decoding the visual signal output into a plurality of individual stimulation control signals which are used by current generation circuitry to generate stimulation current signals to be used by an electrode array having a plurality of electrodes forming a matrix. The intraocular components are powered from energy extracted from the transmitted visual signal. The electrode array is attached to the retina via tacks, magnets, or adhesive.

    摘要: This invention concerns the use of stainless steel, disposable tacks to be employed in the mechanical dilation of the iris during opthalmic surgery. Intended for temporary iris fixation, the tack is provided with a hook built onto its proximal end, and with a sharp anterior blade at its distal end. The anterior blade allows easy insertion of the tack through the peripheral cornea of the eye, at the limbal area, and an applicator is provided with a forked holder to firmly grasp the hook in securely placing and removing the tack in the surgical procedure.

    摘要: Described herein are devices and methods for treating eye conditions. Described is an ocular implant including an elongate member having an internal lumen forming a flow pathway, at least one inflow port communicating with the flow pathway, and at least one outflow port communicating with the flow pathway. The elongate member is adapted to be positioned in the eye such that at least one inflow port communicates with the anterior chamber, at least one outflow port communicates with the suprachoroidal space to provide a fluid pathway between the anterior chamber and the suprachoroidal space when the elongate member is implanted in the eye. The elongate member has a wall material imparting a stiffness to the elongate member. The stiffness is selected such that after implantation the elongate member deforms eye tissue surrounding the suprachoroidal space forming a tented volume.

    摘要: An injectable formulation of therapeutic agent may comprise the therapeutic agent and a stabilizer such that a substantial portion of the stabilizer remains in the therapeutic device to stabilize the therapeutic agent when the therapeutic agent is released from the therapeutic device. The injectable formulation may comprise one or more of binding agent particles or erodible material particles, such that the formulation can be injected into the therapeutic device. The binding agent particles can bind reversibly to the therapeutic agent so as to modulate release of the therapeutic agent, and the erodible material particles can generate protons of an acid so as to increase stability of the therapeutic agent and may modulate release of the therapeutic agent. The therapeutic agent can be combined with one or more of the stabilizer, the binding agent particles or the erodible particles to increase stability of the therapeutic agent and may modulate release.
