The application relates to an eye drop dispensing device optionally including one or more active principles, the device including a dispensing head including an eye drop supply duct, the supply duct having an open dispensing end, and a dispensing surface in the vicinity of the dispensing end, the dispensing surface extending over at least one side of and below the dispensing end, the dispensing end being arranged so as to supply the eye drops to the dispensing surface.

A method of delivering safe, suitable, and repeatable dosages to a subject for topical, oral, nasal, or pulmonary use and a device for droplet ejection includes a fluid delivery system capable of delivering a defined volume of the fluid in the form of droplets having properties that afford adequate and repeatable high percentage deposition upon application. The method and device include a housing, a reservoir disposed within the housing for receiving a volume of fluid, an ejector mechanism configured to eject a stream of droplets having an average ejected droplet diameter greater than 15 microns, the stream of droplets having low entrained airflow such that the stream of droplets deposit on the eye of the subject during use.

Described herein include a system and method for a device for drug delivery and ophthalmic diagnostics designed to assist in the diagnosis of the physical state of a cornea through the projection of droplets onto the eye. In some embodiments, the apparatus includes a liquid sampling unit, an electric droplet generator, and a steering unit. In some embodiments, the liquid sampling unit is configured to project a quantity of liquid, while the electric droplet generator receives the quantity of liquid and outputs one or more electrically charged droplets. The steering unit uses electrostatic forces to steer the electrically charged droplets along a trajectory onto the cornea of the patient's eye.

A cartridge-based device for providing a spritz of medication to a user's eyeball, the device supporting a sealed cartridge comprising at least two metered doses of medication wherein a moveable plug inside the device is actuated to force the medication through an ejection nozzle of the cartridge in the form of a spritz.

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.

A drop delivery system comprising a light source; an optical waveguide bringing light from the light source; and a liquid supplying means configured to bring a liquid at a tip of the optical waveguide, wherein the light source and the optical waveguide are configured to enable the light to eject a drop of the liquid.

The present disclosure provides methods and apparatus for administration of ophthalmic treatments into a patient's eye. Apparatus may include a wire form with a horizontal upper frame, temples that rest on or hook over the ears, nose pads, and semi-circular receivers to accept the tip of an eye drop-dispenser bottle. In some examples, distance sensing apparatus and signaling capabilities may be present to support the administration of ophthalmic treatments. In some examples, the apparatus may be enhanced for the purposes of aiding the application of eyedrops by a deep upper horizontal frame that rests on the forehead to prevent the apparatus, and thereby the eye dropper bottle, from approaching the eye too closely.

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.

Described herein is a delivery device and methods for delivering an ocular implant into an eye. The delivery device includes a proximal handle portion; a distal delivery portion coupled to a distal end of the handle portion and configured to releasably hold an ocular implant and includes a sheath positioned axially over a guidewire; and a metering system configured to provide visual guidance regarding depth of advancement of an implant positioned on the guidewire into an anatomic region of the eye. Also disclosed is a device and method for loading an implant onto the delivery device.

An eyedrop delivery system for the automated dispensing of eyedrop solution from bottles and ampoules. The system includes a battery and electronic control circuitry. A sprocket drive motor directs the advancement of a loop cartridge band containing eyedrop solution ampoules, moving each one at a time into position for dispensing. A motor rotates a cam to strike a push rod to compress each ampoule. The system includes an eyelid retracting leg assembly. The cartridge automatically advances the next full ampoule into position for dispensing and pushes the ampoule tip aside. The system helps assure that: (1) a known number of drops are dispensed; (2) the dispensed eyedrop(s) fall on the eyeball (by providing eyelid retracting legs to keep the eye open); and (3) the eyedrop(s) landing on the surface of the eye are confirmed using a drop dispensing sensor pair and a surface of the eye sensor pair.
