The invention is a retinal implant device to stimulate a retina of an eye thereby producing a specific effect in the eye, such as a vision or drug treatment of a chronic condition. The retinal device is made of a retinal implant that is positioned subretinally and that contains a multitude of stimulation sites that are in contact with the retina. A connection carries a stimulating electrical signal or a drug. The connection passes transretinally through the retina and into a vitreous cavity of the eye, thereby minimizing damage to a nutrient-rich choroid. A lead is attached to a source of drugs or electrical energy, which is located outside the eye. The lead passes through a sclera at a point near a front of the eye to avoid damage to the retina.

Described are systems and methods for preventing, diagnosing, and/or treating one or more medical conditions. The medical conditions can be ocular and/or neurological diseases, disorders, and/or conditions. The systems and methods can employ a microstimulator that is configured to be placed within an anatomical structure of a subject. The microstimulator can be capacitively linked to an external electronic device to provide neuromodulation to a biological target site proximal to the anatomical structure. The microstimulator can include a body and an electrically conductive insert arranged within the body to create a capacitively coupled link with the external electronic device. The electrically conductive insert can receive a power signal from an external electronic device and convert the power signal to deliver a therapy signal to the biological target site.

Described is a compressible tube comprising a tube body made of a specific laminate and shoulder and applicator, said applicator being suitable for applying a tube content in dosed droplets and comprises a sterile venting valve. The tube body has a restoring force (R) sufficient to essentially restore the original volume of the tube body after each of a predetermined number of applications. Such tube is especially suitable for the application of ophthalmic sterile drops.

An implant for insertion through a punctum and into a canalicular lumen of a patient. The implant includes a matrix of material, a therapeutic agent dispersed in the matrix of material, a sheath disposed over a portion of the matrix of material and configured to inhibit the therapeutic agent from being released from the matrix of material into the canalicular lumen and to allow the therapeutic agent to be released from a surface of the matrix of material to a tear film, and a retention structure configured to retain the implant within the canalicular lumen.

The eye nebulizer deploys at least a block piece along a tube for the nebulized medication so as to achieve an S-shaped flow path, thereby preventing the nebulized medication from directly impacting and injuring the eye. In addition, due to the altered and curved flow path, the nebulized medication would diffuse around the rim of the eye cup, thereby covering a wider treatment area around the eye. The eye nebulizer therefore achieves an enhanced treatment effect and a greater applicability.

A device for assisting the placement of drops in the eyes includes a pair of sunglasses having left and right dark tinted lenses; each of the lenses has an aperture formed therethrough for alignment with the left and right eyes when the sunglasses are worn by the user. An insert is fitted within each aperture with the use of an adhesive or by snap-fit attachment. Each insert includes an annular rim on the exterior surface of the lens surrounding the aperture and providing a seat for receipt of an eye dropper nozzle therein. Each insert may further include a tubular extension that passes through the aperture to approximately the thickness of the lens.

An ejector device and method of delivering safe, suitable, and repeatable dosages to a subject for topical, oral, nasal, or pulmonary use is disclosed. The ejector device includes a housing, a reservoir disposed within the housing for receiving a volume of fluid, and an ejector mechanism in fluid communication with the reservoir and configured to eject a stream of droplets, the ejector mechanism comprising an ejector plate coupled to a generator plate and a piezoelectric actuator; the piezoelectric actuator being operable to oscillate the ejector plate, and thereby the generator plate, at a frequency and generate a directed stream of droplets.

A device for inducing production of tears may include a body extending from a proximal end to a distal end. The body may be configured for insertion through a puncta of a subject. The device also may include a stimulus delivery mechanism positioned between the proximal end and the distal end and an induction coil operably coupled to the stimulus delivery mechanism. Further, the device may include an external controller wirelessly coupled to the induction coil for inductively transferring energy to the induction coil.
