Coronary angioplasty is a procedure used to treat the narrowed coronary arteries. Physicians operate with many different tools during the intervention, the main devices are the following: guidewires, guiding catheters, balloon catheters and stents. One of the most important properties of the tools of angioplasty is flexibility. This article introduces a flexibility measuring device and a testing method. With the help of this the flexibility of the tools of angioplasty can be compared easily.

This paper proposes a 3D IC integration TSV testing apparatus, primarily using at least one set of TSV component testing devices with a specific design. Under complex technological conditions, such as varying depth-width ratios of TSVs and heterogeneous IC integration, as well as the principle of different coupling parasitic parameters between TSVs, the TSV coupling measuring device designed for specific purposes in coordination with a measuring method for high-frequency coupling TSV S-parameters, achieves the function of monitoring the SiO2 thickness completeness of TSVs. This feasible approach further allows judgment of whether subsequent processes can continue, effectively reducing costs.

An important practical problem is a personalized selection of characteristics and parameters of intravascular frame to reduce traumatism of inner lining artery - the intima, which, in turn, reduces the instent restenosis. The solution of this problem is due to the phase calculation biomechanical model of the vessel with its stenosed area and implantable stent in accordance with the mechanical and geometric parameters of the pathophysiological characteristics and conditionally normal plots of the artery. The article presents the techniques and methods selection of the geometric characteristics of the stent, the pressure in the balloon used for intravascular angioplasty, taking into account the individual characteristics of the patient´s coronary artery. The selection me-thods are based on biomechanical models of intact areas of the coronary arteries, the parameters were taken from the available references. As the study results are data obtained in simulation of balloon dilation and stenting of the coronary arteries. The presented calculations require biomechanical computer models of axisymmetric and non-axisymmetric stenosed intact aras of the coronary arteries, as well as biomechanical models commonly used stents and dilatation balloon catheters for interventional procedures on coronary arteries.
