<P>PROBLEM TO BE SOLVED: To provide an apparatus for measuring the radial expansion force or a hoop force of a stent or other article. <P>SOLUTION: The apparatus includes: (a) an article engagement mechanism 20 including at least one stationary plate member 47, at least one rotatable force collector member 50 which is moveable in relation to the stationary plate member 47, and a plurality of force element segments, each having a proximal end and a distal end and also having a distal coupling point and a proximal coupling point. The distal coupling point is pivotally coupled to the stationary plate member and the proximal coupling point is pivotally coupled to the rotatable force collector member. The segment distal ends are disposed adjacent a central aperture into which the article is placed, and move to engage the article upon rotation of the rotatable force collector member in a predetermined direction; (b) an actuator 22 for rotating the rotatable force collector member; and (c) a transducer communicatively connected to the actuator for detecting force associated with rotating the rotatable member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
