Abstract:
A bone plug for plugging a channel within a bone to stop a flow of bone cement through said channel, wherein said bone plug comprises:a plurality of flexible beams, extending around a periphery of said bone plug in a longitudinal direction within a central portion of said bone plug between first and second end portions of said bone plug, wherein said plurality of flexible beams includes an outer layer of flexible beams and an inner layer of flexible beams, wherein said inner and outer layers of flexible beams each extend around said periphery of said bone plug, wherein said inner layer of flexible beams extends under said outer layer of flexible beams, and wherein a center of each flexible beam within said inner layer of flexible beams extends beneath a gap between adjacent flexible beams within said outer layer of flexible beams; an actuator movable between a disengaged position and an engaged position, wherein movement of said actuator from said disengaged position to said engaged position applies a compressive force acting between opposite ends of each flexible beam within said plurality of flexible beams, causing said flexible beam within said first plurality of flexible beams to buckle outward; and a latch holding said actuator in said engaged position.
