摘要：
Adjustable flow glaucoma shunts are disclosed herein. In one embodiment, for example, an adjustable flow shunt can include an outflow drainage tube having a proximal inflow region and a distal outflow region. The proximal inflow region can include aperture(s) defining a fluid inlet area positioned to allow fluid to flow therethrough. The shunt further comprises an inflow control assembly at the proximal inflow region. The inflow control assembly can include a control element configured to slidably engage the proximal inflow region and a spring element. The spring element is configured to be activated by non-invasive energy and, upon activation, slidably move the control element along the proximal inflow region such that (a) the one or more apertures are accessible and have a first fluid flow cross-section or (b) the one or more apertures are at least partially covered by the control element and have a second, different fluid-flow cross-section.
