A stent for introduction into a hollow organ of a human or animal body, in particular the gastrointestinal tract includes a stent body being resilient in a radial direction and having a wall defining an inner fluid passageway from one end of the stent body to a longitudinally opposing end of the stent body, and a resilient porous layer. The porous layer covers an outer surface of said wall along its entire circumference and along a predefined section in a longitudinal direction of said stent body. The porous layer and the wall are adapted for applying a negative pressure toward a portion of the hollow organ. The wall forms a liquid-tight barrier separating the inner fluid passageway and the porous layer, at least longitudinally opposing end faces of the porous layer are covered by a liquid-tight cover being connected to the respective longitudinal end of the wall.
A stent (10) for introduction into a hollow organ of the human or animal body, preferably into the gastrointestinal tract, in particular the intestine, comprising
The stent (10) according to any of the preceding claims, further comprising at least one cannula (22) being accommodated by the porous layer (16) outside of the wall (12).
The stent (10) according to any of the preceding claims, wherein the outer circumference of the porous layer (16) is covered with the cover (20) at longitudinal end portions (26 A, B) of the porous layer (16).
The stent (10) according to any of the preceding claims, wherein the wall (12) of the stent body and/or the porous layer (16) are formed of a plastic material or rubber material.
The stent (10) according to any of the preceding claims, wherein the wall (12) of the stent body and/or the porous layer (16) are formed of a silicon-based material, preferably comprising or consisting of silicone.
The stent (10) according to any of the preceding claims, wherein the wall (12) of the stent body and the porous layer (16) are formed of the same material.
The stent (10) according to any of the preceding claims, wherein the wall (12) of the stent body and the porous layer (16) are secured to each other in a material bonding manner.
The stent (10) according to any of the preceding claims, wherein the cover (20) extends from the respective longitudinal end of the wall (12) as a sheet-like material.
The stent (10) according to any of the preceding claims, wherein the cover (20) and the wall (12) of the stent body are formed as a single piece.
The stent (10) according to any of the preceding claims, wherein longitudinally opposing end portions (26A, B) of the porous layer (16) comprise an enlarged radially outward extension.
The stent (10) according to any of the preceding claims, comprising a mesh-shaped frame portion (32) enclosing only a portion of the stent body.
A method for manufacturing a stent (10) suitable for introduction into a hollow organ of the human or animal body, preferably into the gastrointestinal tract, in particular the intestine, comprising the steps of:
