Lorebza Petrini and so on has established the ball pouch expansion type crown arteries support system finite element model, discussed the different modelling strategy which the simulation ball pouch expands the influence which distorts to the support expansion

Lorebza such as Petrini established Balloon dilatation of Coronary Stent System with finite element model, discussed different modeling strategy simulation of Balloon dilatation on stent expansion deformation effects

Lorebza Petrini,etc. has set up the finite element model of the expanding support system of coronary artery of sacculus, different modeling tactics of discussing to imitate the sacculus and expand expand the influence out of shape on the support
