Biliary stent and method manufacturing thereof

A stent (400, 500) made of a biodegradable polymer and to be deployed in a biliary duct, the stent (400, 500) comprising:

• a first end;
• a second end defining a length (L3) of the stent (400, 500) from the first end;
• a plurality of first monofilaments (411, 511) and a plurality of second monofilaments (413, 513) braided at a first predefined braiding angle from the first end to the second end, the plurality of first monofilaments (411, 511) and the plurality of the second monofilaments (413, 513) are back braided at a second pre-defined braiding angle from the second end to the first end thus making a pair of the first monofilaments (411, 511) and a pair of the second monofilaments (413, 513), the pair of first monofilaments (411, 511) and the pair of second monofilaments (413, 513) intersect with each other to define a pre-defined braiding pattern;
• wherein, post axial compression, the length (L3) of the stent (400, 500) is decreased by 25% to 10% and the first and second pre-defined braiding angles of the stent (400, 500) are increased by 25% to 6.25%.

A stent (300) made of a biodegradable polymer and to be deployed in a biliary duct, the stent (300) comprising:

• a first end (310);
• a second end (320) defining a length (L3) of the stent (300) from the first end (310);
• a plurality of first monofilaments (311) and a plurality of second monofilaments (313) braided at a first predefined braiding angle from the first end (310) to the second end (320), at least one of the plurality of first monofilaments (311) or the plurality of the second monofilaments (313) is back braided at a second pre-defined braiding angle from the second end (320) to the first end (310);
• wherein, post axial compression, the length (L3) of the stent (300) is decreased by 25% to 10% and the first and second pre-defined braiding angles of the stent (300) are increased by 25% to 6.25%.
