摘要： 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 an actuation assembly having one or more actuators for controlling the flow of fluid through the system. Each of the actuators can be actuated via energy. The adjustable shunting systems can further one or more energy redirecting elements. Each of the energy redirecting elements can redirect or transmit the received energy to a corresponding actuator. Accordingly, each of the actuators can be independently actuated by applying energy to the corresponding redirecting element.

摘要： A system for delivering energy to implanted devices using electromagnetic wireless charging and associated systems and methods are disclosed herein. In some embodiments, the system includes an energy transmission device and an implanted device. The energy transmission device can include multiple transmission coils, while the implanted device can include one or more receiving coils and one or more chargeable energy storage components. The transmission coils on the energy transmission device can each be energized to generate an electromagnetic field. When the implanted device is positioned within range of the energy transmission device, the receiving coils in the implanted device interact with the electromagnetic fields to generate a current. The current is used to charge the energy storage components.

摘要： The present technology is generally directed to implantable medical devices and associated methods. For example, a system configured in accordance with embodiments of the present technology can include a body implantable into a patient and configured to undergo a shape change, the body having a conductive path with variable conductivity in portions thereof for selective and/or preferential heating. The body can be coupled with an energy source that can delivery energy to the body and/or conductive path, to promote the shape change in the body.

摘要： The present technology is generally directed to shunting systems having shape memory actuation elements that can selectively change a geometry of a shunting element to affect the flow of fluid therethrough. In some embodiments, the shape memory actuation elements are incorporated as part of an onboard resonant circuit. Activating the resonant circuit causes current to flow through the shape memory actuation element, thereby resistively heating the shape memory actuation element.

摘要： 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.
