| titleOfInvention | Self-expandable double plastic stent |
| abstract | A self - expanding non - degradable dual plastic stent being conical in shape is provided with an anti -migration segment (4) and with extracting wires at its proximal end and with an anti-reflux valve (6) at its distal end. The stent is made of two different non - degradable fibres, namely of the PEEK-based carrying fibre (2) and the radiopaque fibre (3), and coated with a silicone foil, the carrying fibre (2) forming the principal skeleton of the stent (1) and the radiopaque fibre (3) enhancing the visibility of the same, the carrying fibre (2) being made of a plastic material selected from the group including PEEK, PEAK, PEK, PEKK, PEKKEK and the other fibre being made of PU+W. The stent (1) is further provided with a pull -tie (5). A method of manufacturing said non - degradable dual conical plastic stent is described, wherein initially the stent is knitted from the first fibre by means of a braiding machine so that it assumes a tubular/ slightly conical shape having the proximal end atraumatic and the distal end traumatic, then the skeleton of the stent is placed oh a mandrel and the other, 1 radiopaque fibre is enlaced into it, both the fibres being laid side by side, afterwards the mandrel with the stent attached to it is removed from the braiding machine and placed into a thermal device where the shape of the stent is thermally fixated by being subjected to a temperature between 120 °C and 250 °C, preferably between 140 °C and 200 °C, during a time interval from 10 to 120 minutes, preferably from 20 to 40 minutes, and finally the stent is provided with the anti -migration segment at its proximal end, said segment comprising one or more fibres forming a ripple at the proximal end of the stent, said ripple adjoining the skeleton of the stent from outside. |
