Corrosion and biocompatibility behaviours of microarc oxidation/phytic acid coated magnesium alloy clips for use in cholecystectomy in a rabbit model.

With the popularisation of laparoscopic cholecystectomy, ligation clips have been commonly used for ligating the cystic duct and cystic artery. However, non-degradable clips remain in the body long-term, which significantly increases the risk of the clip becoming detached. Thus, magnesium alloys have attracted tremendous attention owing to their biodegradability and good biocompatibility.

and performances of chitosan-coated Mg-Zn-Zr-Gd-Ca alloys as bone biodegradable materials in rat models.

Mg alloys have attracted significant attention as promising biomedical materials, specifically as fixation materials for promoting fracture healing. However, their unsatisfactory corrosion resistances hinder further clinical applications and thus require attention. This study aims to determine the performance of novel chitosan-coated Mg-1Zn-0.

Biological behavior exploration of a paclitaxel-eluting poly-l-lactide-coated Mg-Zn-Y-Nd alloy intestinal stent .

As a new type of intestinal stent, the MAO/PLLA/paclitaxel/Mg-Zn-Y-Nd alloy stent has shown good degradability, although its biocompatibility and has not been investigated in detail. In this study, its biocompatibility was evaluated by animal study. New Zealand white rabbits were implanted with degradable intestinal Mg-Zn-Y-Nd alloy stents that were exposed to different treatments.
