A Comparison of a Fully Covered and an Uncovered Segmented Biodegradable Esophageal Stent in a Porcine Model: Preclinical Evaluation of Degradation, Complications, and Tissue Reactions

<div>The stent delivery system. (a) The schematic diagram of the stent delivery system. The delivery system consists of three coaxial tubes. The outer tube serves to constrain the stent until being retracted during the stent deployment. The interior tube contains a central lumen that accommodates a 0.035 in./0.89 mm guide wire. In addition, the delivery system has a balloon catheter. (b) A stent was partly accommodated into a delivery system. The outer tube was 22 Fr. A 0.035-inch guide wire was inserted into the interior tube. (c) The balloon catheter was designed at 28 × 100 mm size; the balloon and a pump for balloon dilation were showed.</div>
