Title (EN) LUMEN EXPANDING STENT AND METHOD FOR MAKING THE SAME
(FR) ENDOPROTHESE S'ETENDANT DANS UNE LUMIERE ET SON PROCEDE DE FABRICATION
Abstract:
(EN) Disclosed herein is a lumen expanding stent comprising a selected stent adapted to a lesion site to be implanted therewith, a polytetrafluoro ethylene sheet tightly adhered to the inner surface of the selected stent, and a medical grade synthetic resin sheathed over the selected stent, wherein the medical grade synthetic resin is sheathed over the selected stent by dipping the polytetrafluoro ethylene sheet adhered to the inner surface of the selected stent in the medical grade synthetic resin, thereby integrally joining the polytetrafluoro ethylene sheet and the medical grade synthetic resin through the selected stent sandwiched therebetween. When the stent is implanted into a lumen or blood vessel, it can prevent a tumor, etc., which propagates at the outside of the stent, from penetrating into the inside of the stent. Further, blood, bile or food remnants can pass through the inside of the stent, without being deposited on wires constituting the stent.
(FR) L'invention concerne une endoprothèse s'étendant dans une lumière comprenant une endoprothèse sélectionnée conçue pour un site de lésion, à implanter au moyen de l'endoprothèse s'étendant dans une lumière, une feuille de polytétrafluoroéthylène étroitement fixée sur la surface intérieure de l'endoprothèse sélectionnée, et la résine synthétique de qualité médicale formant un manchon sur l'endoprothèse sélectionnée, par trempage de la feuille de polytétrafluoroéthylène fixée sur la surface intérieure de l'endoprothèse sélectionnée dans la résine synthétique de qualité médicale, ce qui permet de relier de manière monobloc la feuille de polytétrafluoroéthylène et la résine synthétique de qualité médicale, l'endoprothèse sélectionnée étant prise en sandwich entre ces deux éléments. Lorsque l'endoprothèse est implantée dans une lumière ou dans un vaisseau sanguin, elle permet d'éviter qu'une tumeur, etc., se propageant à l'extérieur de l'endoprothèse, ne pénètre à l'intérieur de l'endoprothèse. En outre, du sang, de la bile et des résidus alimentaires peuvent passer à travers l'intérieur de l'endoprothèse, sans se déposer sur les fils qui constituent l'endoprothèse.
