URETHRAL STENT AND BLADDER CONTROL ASSEMBLY COMPRISING SUCH A URETHRAL STENT

摘要

A urethral stent (1) for arrangement in the urethra of a patient is disclosed, comprising: a tubular body (2) having first (22) and second openings (24), retention elements (3, 4) connected to the tubular body at, or in the vicinity of, the first opening and to the tubular body at a distance from the first retention element, and a valve (5) comprising a valve seat (51) formed by the first opening (22) and a valve element (52) being pivotably connected to the tubular body and/or the valve seat by a hinge (53) connected to the tubular body at one side of the first opening. The valve element is pivotable between a closed position, in which the valve element is in engagement with the valve seat at the first opening, thereby closing the lumen, and an open position in which the valve element is pivoted away from the valve seat, thereby opening the lumen. The valve element is at least partly made of a ferromagnetic material and has an area which exceeds the area of the first opening. The stent further comprises at least one pivot restriction element (7) arranged in the vicinity of the first opening and in the vicinity of the hinge, and protruding away from tubular body. A bladder control assembly comprising the urethral stent is also disclosed.
