The M-type stent is designed with closed cells, ideal for maintaining conformation and minimizing the risk of migration. Its interwoven structure offers great radial strength, making it suitable for severely stenosing lesions or extrinsic compression. It is compatible with endoscopic or percutaneous delivery and is available in multiple lengths and diameters. It also stands out for its versatility in multiple configurations, allowing for placement in right and left branches with simultaneous delivery using low-profile sheaths. Its design facilitates sustained bile flow and reduces the risk of post-procedural complications.
