Development in Intracoronary Stents
I n 1964, Dotter et al used the term “stent” to describe wire tubular implants that could be placed in femoral arteries of animals with non-surgical techniques for the first time. The first reports on the use of intravascular stents were made much later, in 1983, by Dotter et al and Gragg et al who placed a wire spring of nitinol in arteries of dogs using a catheter. These reports served as a c...
متن کاملAdjuvant therapy for intracoronary stents. Investigations in atherosclerotic swine.
Early thrombosis has complicated human stent implantation in several trials. To determine the best anticoagulation/antiplatelet therapy to maintain stent patency after percutaneous transluminal coronary angioplasty, we implanted the flexible balloon-expandable coil stent into the left anterior descending coronary artery of 28 atherosclerotic 8-month-old Hanford miniature swine. Animals were ran...
متن کاملIntracoronary brachytherapy for in-stent restenosis of drug-eluting stents
PURPOSE Given the limited salvage options for in-stent restenosis (ISR) of drug-eluting stents (DES), our high-volume cardiac catheterization laboratory has been performing intracoronary brachytherapy (ICBT) in patients with recurrent ISR of DES. This study analyzes their baseline characteristics and assesses the safety/toxicity of ICBT in this high-risk population. METHODS AND MATERIALS A re...
متن کاملMultiobjective Optimization of Intracoronary Stents by Genetic Algorithm
In this paper an innovative balloon-stent design method, which conjugates 3D finite-element approach, is presented. The method is based on a large strain and large displacement formulation, with multi-objective optimization using Genetic Algorithm (GA). This procedure allows us to automatically obtain new geometries that improve stent performance and to analyze the relationship between geometri...
متن کاملStents for intracoronary placement: current status and future directions.
The technique of intracoronary stenting has achieved remarkable progress over the last few years. Improved stent deployment techniques and optimization of postprocedural management have dramatically improved the safety of intracoronary stent placement. At present, the incidence of early vessel closure after stenting is even lower than that after standard angioplasty and, as most operators no lo...
