Newly designed “pieced” stent in a rabbit model of benign esophageal stricture

Figure 1 Example of a conventional stent. A conventional stent designed for a rabbit’s esophagus (Shandong Provincial Institute of Medical Instruments, Jinan, China). This type of stent can remold and maintain luminal patency through a long-term dilation effect, but its radial force cannot be changed and may impede stent removal.
