Implant having MEMS Flow Module with Movable, Flow-Controlling Baffle

Various embodiments of MEMS flow modules that may be disposed in a flow path ( 296 ) of a shunt ( 290 ) are disclosed, where the shunt ( 290 ) may be used to control a flow out of an anterior chamber ( 284 ) of an eye ( 266 ). One such MEMS flow module ( 58 ) has a tuning element ( 78 ) and a lower...

Zusammenfassung:	Various embodiments of MEMS flow modules that may be disposed in a flow path ( 296 ) of a shunt ( 290 ) are disclosed, where the shunt ( 290 ) may be used to control a flow out of an anterior chamber ( 284 ) of an eye ( 266 ). One such MEMS flow module ( 58 ) has a tuning element ( 78 ) and a lower plate ( 70 ). A plurality of springs or spring-like structures ( 82 ) interconnect the tuning element ( 78 ) with the lower plate ( 70 ) in a manner that allows the tuning element ( 78 ) to move either toward or away from the lower plate ( 70 ), depending upon the pressure being exerted on the tuning element ( 78 ) by a flow through a lower flow port ( 74 ) on the lower plate ( 70 ). The tuning element ( 78 ) is disposed over this lower flow port ( 74 ) to induce a flow through the MEMS flow module ( 58 ) along a non-linear (geometrically) flow path.
