Title (EN) DRUG-RELEASING BIODEGRADABLE STENT
(FR) ENDOPROTHÈSE BIODÉGRADABLE À LIBÉRATION DE MÉDICAMENT
(KO) 약물방출형 생분해성 스텐트
Abstract:
(EN) The present invention relates to a drug-releasing biodegradable stent comprising: a first stent structure having metal wires, which are formed from a shape memory alloy material, woven into a particular pattern on a jig, and thus having a plurality of cells by means of the crossing wires of the woven structure and formed in the shape of a hollow trunk; and a second stent structure which covers the outer peripheral side of the first stent structure or of which the outer peripheral side is covered by means of the first stent structure. The second stent structure is a 3D printed product which is formed in the shape of a hollow trunk and has a plurality of cells by means of crossing wires of a printed structure formed by means of 3D printing using a printing material comprising a biodegradable polymer and a drug.
(FR) La présente invention concerne une endoprothèse biodégradable à libération de médicament comprenant : une première structure d'endoprothèse à base de fils métalliques, qui sont formés à partir d'un matériau d'alliage à mémoire de forme, tissés selon un motif particulier sur un gabarit, et comportant ainsi une pluralité de mailles définies par le croisement des fils de la structure tissée et affectant la forme d'un tronc creux; et une seconde structure d'endoprothèse qui recouvre le côté périphérique extérieur de la première structure d'endoprothèse ou dont le côté périphérique extérieur est recouvert au moyen de la première structure d'endoprothèse. La seconde structure d'endoprothèse est un produit imprimé en 3D qui affecte la forme d'un tronc creux et comporte une pluralité de mailles définies par le croisement des fils d'une structure imprimée formée par impression 3D à l'aide d'un matériau d'impression comprenant un polymère biodégradable et un médicament.
(KO) 본 발명은 약물방출형 생분해성 스텐트에 관한 것으로, 형상기억합금 소재의 금속와이어가 지그 상에 특정 패턴으로 엮임으로써, 엮임 구조상의 와이어 교차 형태에 의해 다수의 셀(Cell)을 구비하며 중공의 통 형상으로 마련되는 제1스텐트 구조체; 및 생분해성 고분자 및 약물을 포함하는 인쇄재료를 이용해 3D 프린팅을 수행하여 프린팅 구조상의 와이어 교차 형태에 의해 다수의 셀(Cell)을 구비하며 중공의 통 형상을 갖추도록 마련되는 3D 인쇄물로서, 상기 제1스텐트 구조체의 외주면을 덮거나 상기 제1스텐트 구조체에 의해 외주면이 덮이도록 설치되는 제2스텐트 구조체;를 포함한다.
