LASER DIMPLED STENT FOR PREVENTION OF RESTENOSIS

A dimpled stent design has geometrical characteristics, namely dimple width and depth, which generate dimple site specific turbulence and thrust within the blood flow to reduce or eliminate restenosis. The dimpled stent design is produced by laser processing of the stent material to produce differen...

Beschreibung
Zusammenfassung:	A dimpled stent design has geometrical characteristics, namely dimple width and depth, which generate dimple site specific turbulence and thrust within the blood flow to reduce or eliminate restenosis. The dimpled stent design is produced by laser processing of the stent material to produce different sizes, which may be predicted by a Multiphysics computational model, placements, and spatial layouts of dimples in the stent. La présente invention concerne une conception d'endoprothèse alvéolée présentant des caractéristiques géométriques, à savoir une largeur et une profondeur d'alvéole, qui génèrent une turbulence et une poussée spécifiques au site de l'alvéole à l'intérieur du flux sanguin pour réduire ou éliminer la resténose. La conception d'endoprothèse alvéolée est produite par traitement laser du matériau d'endoprothèse pour produire différentes tailles, qui peuvent être prédites par un modèle de calcul multiphysique, des mises en place, et des agencements spatiaux des alvéoles dans l'endoprothèse.
