Systems and methods for a membrane-free electrolysis pump for an intraocular implant

摘要

A microfluidic pump for implantation proximate an eye of a patient is provided herein. The pump includes a first substrate portion and a second substrate portion adjacent the first and a chamber that has a bottom surface and a top surface provided by the first and second substrate portions. A gas is produced within the chamber so that it displaces fluid from the chamber. The pump also includes an inlet channel and an outlet channel coupled to the chamber, the inlet channel being separated from the chamber by a first gap and the outlet channel separated from the chamber by a second gap. The gaps inhibit the gas from moving out of the chamber. Other microfluidic pumps and intraocular devices are also disclosed.

1. A microfluidic pump for implantation proximate an eye of a patient, the microfluidic pump comprising:
a first substrate portion; a second substrate portion adjacent to the first substrate portion; a channel defined by and between the first and second substrate portions and having a proximal end and a distal end, the channel having a first valve in the proximal end and a second valve in the distal end; and a chamber having a bottom surface, side surfaces, and a top surface, wherein the top surface is provided by a rigid, liquid-permeable wall, the chamber producing a gas within the chamber that displaces fluid within the chamber and within the channel, the rigid, liquid-permeable wall being in fluid communication with the channel.
