In this paper we suggest a general procedure to model tube-shaped stents by CAD, in particular of intravascular coronary kind. The methodology utilisation is highly independent of modelization softwares and enables us to build up careful stent models. These models can be usefully used to perform structural and/or blood fluid dynamic analysis. The procedure is based on particular considerations of Descriptive Geometry that are inspired by the laser cutting technology of the stents. The study is developed by using a hybrid technique of surfaces and solids modelling. The method suggested is illustrated with reference to a class of intracoronary stents cut by laser beam. Some general conclusions show how it is possible to apply the procedure also for modelling of stents manufactured by using welded stainless steel wire.

Abstract
In this paper we suggest a general procedure to model tube-shaped stents by CAD, in particular of intravascular coronary kind. The methodology utilisation is highly independent of modelization softwares and enables us to build up careful stent models. These models can be usefully used to perform structural and/or blood fluid dynamic analysis. The procedure is based on particular considerations of Descriptive Geometry that are inspired by the laser cutting technology of the stents. The study is developed by using a hybrid technique of surfaces and solids modelling. The method suggested is illustrated with reference to a class of intracoronary stents cut by laser beam. Some general conclusions show how it is possible to apply the procedure also for modelling of stents manufactured by using welded stainless steel wire.Pubblicazioni consigliate
