1. A microactuator adapted for inhibiting the formation of obstructions in a drainage passage that has a round interior cross-sectional shape, the microactuator comprising:
a frame; and
an appendage anchored to and cantilevered from the frame such that the frame supports the appendage, the frame at least partially surrounds the appendage, and the appendage is disposed in an opening or window defined by the frame, the appendage comprising a platform and at least one beam that anchors the platform to the frame to enable the appendage to deflect relative to the frame, the platform comprising a ferromagnetic material that enables the appendage to deflect in response to an applied magnetic field;
wherein the platform is connected at a first end thereof to the at least one beam, has a second end that is oppositely disposed from the first end, and has a rounded distal edge at the second end having a parabolic shape that is complementary to the round interior cross-sectional shape of the drainage passage.
