    摘要： The electronically switchable MEMS valve includes a housing formed from soft magnetic material and defining a fluid flow path therethrough. A magnetic field generating member is mounted within the housing and connected to a source of electrical power. A MEMS valve portion is mounted within the magnetic field generating member, has a valve closing member movably mounted therein, and defines a portion of the fluid flow path therethrough. The valve closing element is movable between a closed position wherein the fluid flow path is blocked, and an open position wherein the fluid flow path is not blocked. When an electric current is removed from the magnetic field generating member, the valve closing element is configured to move to and remain in the one of the closed position and the open position to which the valve closing element is the closest when the electric current is removed.

    摘要： A substantially leak-free, sealable microvalve that can be repeatedly opened and sealed is presented. The resealable microvalve includes a block with a through via and a sealing plate. The gap between the block and the sealing plate is sealed by a sealing material. The sealing material can be melted when heat is applied and can be solidified when heat is absent. To close the resealable microvalve, heat is applied by flowing a current through a resistive heater and an actuator brings the block and the sealing plate into a contacting position. By removing the heat, the sealing material is solidified and creates a sealed state. To open the resealable microvalve, heat is applied to the sealing material. When the sealing material melts, the actuator moves the block and the sealing plate into a spaced apart position.

    摘要： An implanted parylene tube shunt relieves intra-ocular pressure. The device is implanted with an open end in the anterior chamber of the eye, allowing excess fluid to be drained through the tube out of the eye. In one embodiment, only a first end of the tube implanted into the anterior chamber of the eye is open. Intra-ocular pressure (IOP) is then monitored, for example utilizing an implanted sensor. When IOP exceeds a critical valve, a practitioner intervenes, puncturing with a laser a thinned region of the tube lying outside the eye, thereby initiating drainage of fluid and relieving pressure. In accordance with alternative embodiments, the both ends of the tube are open, and the tube includes a one-way valve configured to permit drainage where IOP exceeds the critical value. The tube may include projecting barbs to anchor the tube in the eye without the need for sutures.

    摘要： A latching microregulator for regulating liquid flow on micro-scale levels comprises a substrate having an inlet port and an outlet port, a valve element defining a valve chamber for opening and closing the inlet port, and an actuator assembly for actuating the valve element. The valve chamber is configured to contain a volume of fluid, and the inlet port and the outlet port are in fluid communication with the valve chamber to provide a liquid flow path through the chamber. The actuator assembly comprises a cantilever beam for moving the valve element between an open position and a closed position, an actuator, such as a piezoelectric element, for moving the cantilever beam, and a latch, such as a permanent magnet, for securing the cantilever beam in the closed position. A flow regulation system comprises a plurality of fluid channels of varied flow conductance and a plurality of latching microregulators for selectively blocking or allowing flow through each of the fluid channels.
