Title (EN) HOLLOW DRUG-FILLED STENT AND METHOD OF FORMING HOLLOW DRUG-FILLED STENT
(FR) STENT CREUX REMPLI DE MÉDICAMENT ET SON PROCÉDÉ DE FORMATION
Abstract: front page image
(EN)A stent (100) is formed from a wire (102) that in cross-section includes an outer member (102) having a lumen (103) and a radiopaque core member (124) partially filling the lumen. A therapeutical substance (112) for elution through openings formed through the outer member fills the portion of the lumen not filled by the radiopaque core member. In a method of forming the stent, a composite wire including an outer member and a dual core member is shaped into a stent pattern. The dual core member includes a first core member and a second, radiopaque core member. The shaped composite wire is processed to remove the first core member from the outer member without adversely affecting the outer member and the second core member. The portion of the lumen that was occupied by the first core member may be filled with a substance for elution through openings from through the outer member to the lumen.
(FR)L'invention concerne un stent (100) formé à partir d'un fil (102) qui comprend en section transversale un élément externe (102) ayant une lumière (103) et un élément d'âme radio-opaque (124) remplissant partiellement la lumière. Une substance thérapeutique (112) pour l'élution à travers des ouvertures formées à travers l'élément externe remplit la partie de la lumière qui n'est pas remplie par l'élément de noyau radio-opaque. Selon un procédé de formation du stent, un fil composite comprenant un élément extérieur et un élément à noyau double est façonné sous la forme d'un modèle de stent. L'élément à noyau double comprend un premier élément de noyau et un second élément de noyau radio-opaque. Le fil composite formé est traité afin de retirer le premier élément de noyau de l'élément externe sans affecter l'élément externe et le second élément de noyau. La partie de la lumière qui était occupée par le premier élément de noyau peut être remplie d'une substance pour l'élution à travers des ouvertures à travers l'élément externe à la lumière.
