Claim:
1. An apparatus for self-clearing a flow pore in a human implant, comprising: a housing configured to be disposed in a flow pore of the implant; said housing comprising a central bore spanning between an upper surface and a lower surface of the housing, the central bore providing fluid communication into said flow pore; and an actuator plate extending from the upper surface of the housing into the central bore via a cantilever beam; the cantilever beam having a first end emanating at the central bore and a second end terminating at the actuator plate; the actuator plate configured to reciprocate within the central bore between a first position extending downward at an angle into the central bore and a second position substantially at or above the upper surface of the housing; wherein the cantilever beam is stressed such that it is preloaded to nominally curve downward to extend the actuator plate in the first position; wherein the actuator plate comprises a magnet responsive to magnetic field such that the magnetic field drives the actuator plate toward the second position; wherein in the cantilever beam comprises a composite material having a first low-stress layer and a second compressed layer; and wherein the second compressed layer preloads the cantilever beam to nominally curve in the first position.
