Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

An apparatus includes a pad assembly, an injector assembly, an injector driver, and a fluid source. The pad assembly is sized and configured to be placed on a forehead of a patient. The injector assembly includes a body, a flexible cannula, and a needle. The body is configured to be removably secured to the pad assembly. The cannula is sized to be inserted through an incision in an eye of a patient. The needle is slidably disposed in the cannula. The injector driver is operable to drive the needle longitudinally relative to the flexible cannula. The fluid source assembly is in fluid communication with the needle.

Multi-dose ocular fluid delivery devices are provided. Aspects of the fluid delivery devices include a fluid package and an actuator. The fluid package includes a reservoir of an ophthalmic formulation, an aperture and a valve member for sealing the aperture when fluid is not being ejected therethrough. The actuator is configured to operate the valve member so as to at least reduce, if not prevent, ingress of outside materials or contaminants into the reservoir, such that the ophthalmic formulation present in the reservoir does not require a preservative (e.g., where a preservative-free ophthalmic formulation is present in the reservoir). Also provided are methods of using the devices in fluid delivery applications, as well as a kit that includes components of the devices.

An ophthalmic solution discharging apparatus is described. The ophthalmic solution discharging apparatus comprises: a base portion comprising a cylindrical base for receiving and removably engaging a dropper of an ophthalmic solution container; a head portion comprising a micro nozzle portion through which ophthalmic solution is discharged, a shield portion that cylindrically surrounds the micro nozzle portion, the shield portion comprising a wall containing an opening for viewing a portion of the micro nozzle portion during discharge; a neck portion that connects the base portion and the head portion; and an internal cavity portion defined by the base, head and neck portions and comprising a (1) container engagement portion for receiving and removably engaging the ophthalmic solution container, and (2) a funnel portion for transporting and discharging ophthalmic solution through the micro nozzle portion at a lesser volume than would otherwise be discharged by the dropper of the ophthalmic solution container.

A handheld applicator designed to transfer a liquid drop of ophthalmic medicament into a human eye. The basic structure comprises a finger grip section and a drop retainer section, preferably connected to the grip section with an extension. The device is made from an elastomeric material that will allow for the safe transfer of a liquid drop into the eye. A drop dispensed from a container is placed onto the drop retainer section of the device where the surface tension provides drop adhesion. The user may administer the drop, without having to tilt the head, while maintaining an eyeglass assisted view into a mirror. Application of the drop occurs from the peripheral line of vision. When contact is made to the eye, surface tension is relieved and the drop safely transfers into the eye. The same applicator may have a drop retainer section with a different structure on each side.

Described is a delivery system for percutaneous delivery and implantation of a heart valve. The delivery system includes a handle with a sheath extending therefrom. A splay shaft extends from the handle through the sheath. At least two arms extend from the handle through the splay shaft. The at least two arms are operable for holding a heart valve. A sheath controller is housed within the handle and is operable for selectively advancing or retracting the sheath to constrain or expose a heart valve as attached with the at least two arms. A splay shaft controller is housed within the handle for allowing the user to selectively advance or retract the splay shaft to constrain or expose the at least two arms. Finally, a valve release is attached with the handle to allow a user to selectively release a heart valve as attached with the at least two arms.

A child resistant nasal sprayer assembly includes a cap body having a base portion and an upstanding wall extending axially in an upward direction. An actuator is rotationally and axially slideably assembled within an interior of the upstanding wall. A safety button extends through the actuator and into a receiving notch formed in the upstanding wall. The safety button restricts motion of the actuator when placed in a locked configuration and enables motion of the actuator when placed in an unlocked configuration. The safety button is integral with a ring portion. The ring portion provides a biasing force to the button to retain the button in the locked position until purposely unlocked. Once unlocked, the operator compresses a pair of winglets, which operates a pump that dispenses medicinal composition stored within the bottle through a nozzle.

The current invention discloses a fluid dispenser especially suitable for ophthalmic treatments and delivering of ophthalmic agents such as eye drops. The fluid dispenser incorporates a tube made from compliant materials as the key dosing component. A first point and a second point on the tube may be acted upon by folding the tube or by external elements, making the segment between the first point and the second point a squeezing section that houses a dosing chamber. The squeezing section may be pressed by an anvil or other structures, pressurizing the fluid contained in the dosing chamber so that once the tube is released on one point, the fluid in the dosing chamber is discharged. With each dosing process, a single dose of the fluid is discharged. In addition, the fluid dispenser is capable of delivering a series of doses of the fluid by repeating the dosing process.
