摘要

The invention relates to a bendable structure 40 comprising a body 41 conceived to be bent; an actuator 42, 43, 44 for inducing a bending force in the body, wherein the actuator comprises a wire at least partially manufactured from a uni-directional shape memory alloy (SMA) material, said wire being pre-deformed and being arranged in contact with a portion of the body for forming a bridge structure conceived to transfer mechanic energy across the bridge. The bendable structure 40 may relate to a bendable catheter or an endoscope.
