Abrégé
(EN)
Embodiments relate to systems and methods for magnetized stent having growth-promoting properties. A stent assembly comprising a tubular elongated body having a magnetized region and a tissue nidus area is inserted beneath the orifice of a vascular aneurysm. The magnetic region can serve to attract and position both residua! red biood cells and magnetically nano-ireated growth-promoting ceils to the orifice area of the aneurysm. The outer circumference of the tubular elongated body can act as a floor or scaffold for regenerated smooth vascular muscle cells. In embodiments, the tissue nidus area can be provided on the exterior stent, while the magnetized region is provided on the interior stent, of a stent-in-stent structure. In embodiments, the exterior stent is made of biodegradable material which gradually dissolves or dissipates in situ.

L'invention concerne, dans des modes de réalisation, des systèmes et des procédés relatifs à une endoprothèse magnétisée ayant des propriétés favorisant la croissance. Un ensemble endoprothèse comprenant un corps tubulaire allongé ayant une région magnétisée et une zone de nidus tissulaire est introduite sous l'orifice d'un anévrisme vasculaire. La région magnétique peut servir à attirer et positionner les globules rouges résiduels et les cellules favorisant la croissance nano-traitées magnétiquement vers la zone d'orifice de l'anévrisme. La circonférence extérieure du corps tubulaire allongé peut servir de plancher ou d'échafaudage aux cellules de muscles vasculaires lisses régénérées. Dans des modes de réalisation, la zone de nidus tissulaire peut être prévue sur l'endoprothèse extérieure, tandis que la région magnétisée est prévue sur l'endoprothèse intérieure, dans une structure endoprothèse-en-endoprothèse (stent-in-stent). Dans des modes de réalisation, l'endoprothèse extérieure est à base de matériau biodégradable qui se dissout ou se disperse progressivement in situ.
