Replenish, Inc.™ has developed a small, refillable, implantable ocular drug pump. The MicroPump™ implant is a “smart device” that is programmable to dispense nanoliter-sized doses (a volume sensor gives closed-feedback) of drugs every hour, day or month as needed before refills. The tiny MicroPump™ can be ‘replenished’ using a disposable, proprietary 31-gauge needle tubing kit.

Some of the pump’s features include the following:

•  One-way check valve (prevents backflow leakage)
•  Fluidic flow sensor
•  Bi-directional telemetry system for wireless programming and battery recharges
•  Programmable state-of-the-art microcontroller with calendar to ‘wake up’ when it’s time for medication
•  Optional cannula with pars plana clip directs medication in the same location as intravitreal injections
