ADVANCES IN EUS-BD: A STRUCTURAL PERSPECTIVE ON DEVICE DESIGN

Abstract

The safety and efficacy of EUS-BD have markedly improved due to recent advancements in device design. This review highlights the structural characteristics and clinical significance of the Key devices used in EUS-BD—including puncture needles, guidewires, dilators, and stents—based on the latest literature. Notably, many of these innovative devices were developed in Japan, and their global adoption is expected to further enhance the technical outcomes of EUS-BD.
