A novel planar batch manufacturing approach for coronary stents demonstrates favorable mechanical properties, including minimal recoil and comparable radial stiffness to commercial stents.
Takahata et al. (2004) studied this question. Planar batch manufacturing technologies for coronary artery stents vs. Commercially available stents was evaluated on Mechanical evaluation (diameter variations, radial recoil, longitudinal shrinkage, radial stiffness, bending compliance). Free-standing stents fabricated using planar batch manufacturing exhibited diameter variations of <±4%, almost zero radial recoil, and longitudinal shrinkage of <3% upon expansion.
