  • Publication number: 20220387217
    Abstract: The present technology is directed to adjustable flow glaucoma shunts, systems, and methods for making and using such devices. In many of the embodiments described herein, the shunts include a drainage element configured to fluidly couple an anterior chamber of an eye and a target outflow location, such as a subconjunctival bleb space. The shunts can further include a flow control assembly coupled to the drainage element and configured to control the flow of fluid (e.g., aqueous) therethrough. The shunts can further include an outer membrane or bladder that encases the flow control assembly. The outer membrane can include a plurality of apertures that fluidly couple an interior of the outer membrane with an environment exterior to the outer membrane.
