摘要

In the present invention, there is disclosed a stent designed to stop esophageal variceal bleeding consisting of an elastic mesh (1), the active length, which is the part of the stent that should cover the bleeding varices is covered with impermeable foil (4). At least one end of the elastic mesh (1) is provided with a funnel-shaped throat (2). After being implanted, the elastic mesh (1) presses the impermeable foil (4) against the esophageal wall and thus the bleeding is prevented. After the bleeding is stopped, the stent removal is made by grasping and pulling the loop (3) of the stainless-steel elastic pursing string (5), which is passed through the eyelets (6) made of the wire at both ends of the stent. The elastic pursing string (5) enables the concentric and symmetric constriction of the stent diameter. The elastic mesh (1) with the funnel-shaped throat (2) and the impermeable foil (4) can be made of biodegradable material resulting in a stent disintegration a certain period after the bleeding is stopped.
