Abstract
Official abstract text for this publication.
A microfluidic pump for implantation proximate an eye of a patient is disclosed herein. The microfluidic pump includes a first substrate with a microfluidic actuator that includes a first chamber and a second chamber coupled by a channel, an electrode in each of the chambers, and a slug positioned within the channel. The slug is displaceable by an electric potential. The microfluidic actuator of the microfluidic pump includes a reservoir aligned with the chamber, a membrane portion separating the reservoir and the chamber, and a second reservoir aligned with the second chamber. A second membrane portion separates the second reservoir and the second chamber. Each of the reservoirs has an inlet and an outlet; each of the inlets has a valve that prevents backflow. A second substrate of the microfluidic pump includes a flow path coupling the outlet of the first reservoir to the inlet of the second reservoir.
First claim
Opening claim text (preview).
What is claimed is: 1. A microfluidic pump for implantation proximate an eye of a patient, the microfluidic pump comprising: a first substrate that includes a microfluidic actuator, the microfluidic actuator comprising: a first chamber and a second chamber coupled by a channel; an electrode in each of the first and second chambers; and a slug positioned within the channel, the slug being displaceable by applying an electric potential to an electrolytic fluid in the first and…
