The present technology is directed to implantable medical devices for draining fluid from a first body region to a second body region. Some embodiments of the present technology provide adjustable devices that are selectively titratable to provide various levels of therapy. For example, the adjustable devices can have a drainage element with a lumen extending therethrough, a flow control element, and an actuation assembly. The actuation assembly can drive movement of the flow control element to change a dimension of and/or a flow resistance through the lumen, thereby increasing or decreasing the relative drainage rate of aqueous from an eye. In some embodiments, the actuation assembly and the flow control element together operate as a ratchet mechanism that can selectively move the flow control element between a plurality of positions and lock the device in a desired configuration until further actuation of the actuation assembly.

The present technology relates to intraocular shunting systems and methods. In some embodiments, the present technology includes intraocular shunting systems that include a drainage element having an inflow portion configured for placement within an anterior chamber of the eye outside of an optical field of view of the patient and an outflow portion configured for placement at a different location of the eye. The system can also include a flow control assembly having a rotational control element operably coupled to the drainage element. The flow control assembly can further include an actuation structure coupled to the rotational control element and configured to selectively change an orientation of the rotational control element. An amount of fluid through the inflow portion and/or the outflow portion can vary based on the selected orientation of the rotational control element.

Shunting systems with rotation-based flow control assemblies, and associated systems and methods

The present technology is generally directed to adjustable shunting systems for draining fluid from a first body region to a second body region. The adjustable shunting systems include a flow control plate or cartridge for controlling the flow of fluid through the system. For example, the flow control plate can include a shape memory actuation assembly having one or more nitinol actuators for controlling the flow of fluid through the system. The flow control plate can further include a plurality of discrete sheets or layers adhered together to encase the shape memory actuation assembly. The discrete sheets or layers can form flow channels for directing fluid through the flow control plate.
