Evaluation of the efficacy and safety of a stent covered with biosynthetic cellulose in a rabbit iliac artery model.

Objectives: We sought to test the efficacy and safety of the implantation of a stent covered with biosynthetic cellulose compared to a conventional bare-metal stent (BMS) in a rabbit iliac artery model.

Background: Biosynthetic cellulose is a biocompatible film used in several fields of medicine. Stents covered with biosynthetic cellulose are devices with the potential of achieving total lesion coverage, acting as a physical barrier to the migration of smooth muscle cells from the artery wall to the arterial lumen, and capturing circulating endothelial progenitor cells that may form a functional endothelial layer.
