Balancing the ideal radial supporting performance with flexibility in polymer stents has always been a significant challenge, and a potential solution to which is provided by the mixed‐braided stents. However, the principles of mechanics and design advantages are yet ambiguous. This study aims to establish a correlation between radial supporting performance and structural morphologies of mixed‐braided stents in the compression process. First, this study establishes a computational framework, which takes into account the different material properties of thick and thin monofilaments as well as actual friction coefficients. Second, this study simulates the crimping process of different mixed‐braided stents to find out the relationship between radial supporting performance and structural morphologies. Finally, by changing the friction coefficient in the simulation model, the influence of friction coefficient on the crimping process of the stents is explored. The result provides a reference for the structural design of mixed‐braided stents: significant differences in diameter and friction coefficient can lead to the instability of the stent. Specifically, as the friction coefficient increases from 0.12 to 0.20, the radial stiffness increases from 0.32 to 0.69 N/mm2, which is an increase of 115%. However, the stability of the stent decreases simultaneously. Meanwhile, the COF and stability of the stent have declined.

Hydrogenated amorphous carbon (a-C:H) has been considered a promising biocompatible coating to protect metallic alloys against corrosion for medical applications, namely orthodontics. However, there is still no optimal solution for this biomedical field; hence, the investigation remains open. In this work, the effect of a nonmetallic doping element (N) on sputter-deposited a-C:H coatings was studied concerning both salivary corrosion and cytotoxicity behavior. After a 30-day corrosion test in an acidic modified Fusayama-Meyer artificial saliva, metal release from both coated and uncoated 316L stainless steel (SS) substrates was quantified. Tests on the corrosion extracts were then performed by using monocultures of macrophages and fibroblasts, and their coculture; and cell viability was evaluated via the MTT test. Results show an overall inhibition of the SS corrosion, which enhanced the in vitro biocompatibility with a minimal effect on the coatings’ microstructure. Among all the coatings tested, the undoped a-C:H coating performed the best, whereas an increase in N doping led to poorer protection against metal dissolution and a subsequent slightly lower biocompatibility. The findings corroborate that selecting the nonmetallic element N for doping C-based coatings is not a good choice for this biomedical field, even at low contents up to 10 at.%.
