摘要
The stent designed to stop esophageal variceal bleeding consists of the elastic mesh (1), the active length (that 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 edges 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 which produces the stent disintegration after a certain period since the bleeding is stopped.
