Abstract: The present disclosure provides sterilizable and re-usable devices for injecting substances including, without limitation, viscoelastics, liquids, gels, solutions, emulsions, suspensions, other fluids, and the like, during surgical procedures.

Abstract: Described is a digital microfluidics system and method for measuring an analyte concentration in a droplet. Droplet movement operations can be used to carry out biological, biochemical, and chemical reactions, measurements, and experiments and a light source and light detector or spectrophotometer can be used to transmit light through a droplet to determine the absorbance of light through the droplet to calculate a concentration of analyte in the droplet.

Abstract: Methods of solution-phase kinetic analysis on a digital microfluidic (DMF) device are disclosed. In some embodiments, the methods of solution-phase kinetic analysis on a DMF device provide a DMF system including a DMF device (or cartridge) further including one or more electrode arrangements. The methods may utilize a variety of detection methods including surface plasmon resonance and fluorescence based techniques.

Abstract: An apparatus for delivering an implant to an eye using hydraulic fluid flow or pressure. An implant may be stored, advanced, and delivered to an eye using hydraulic fluid stored in a sterile container through a hollow advancement plunger. The plunger may rigidly advance the implant to a sealed position in a first phase, and then the implant may be advanced into the eye via hydraulic pressure or fluid flow in a second phase.

Abstract: Various embodiments are generally directed to devices and methods for multi-liquid storage and mixing, such as with a medical liquid packaging device (MLPD), for instance. Some embodiments are particularly directed to an MLPD that includes first and second reservoirs that store separate liquids that may be selectively combined prior to administration to a patient. In one or more embodiments, for example, a device for medical liquid packaging may include a first reservoir and a dispensing port with a second reservoir. In a first state, a flow preventer separates the liquid in the first reservoir from the liquid in the second reservoir. Actuation of an actuator, such as by depression of the actuator, dislodges the flow preventer, allowing fluid communication between the first reservoir and the second reservoir.

Abstract: An automatic fertilizing apparatus (10) connected in series with a watering system (150) that includes a water source (152) and a sprinkler head(s) (158). The apparatus (10) consists of a liquid fertilizer container (12) having a water inlet port (20) and a water/fertilizer outlet port (24), and a fertilizing control assembly (50) having an outer fertilizer control tube (52) and an inner fertilizer control tube (82). The tube (52) which includes an outlet fertilizer entry slot (54) is inserted through the port (20) and the port (24) and is fixedly attached therethrough. The tube (82) is rotatably inserted into the tube (52) and includes an inner fertilizer entry slot (84), an inlet end (86) connected to the water source (152), an outlet end (88) connected to the sprinkler head(s) (158) and a vortex tube (87).
