Development of a Virtual Balloon Angioplasty Treatment Simulation Device Based on the Spring-Damper Method

Stroke is one of the chronic conditions that lead to an 85% of death rate from cardiovascular disease in this world. A stroke is when brain cells will not work correctly or even stop working because brain cells do not get enough oxygen from the bloodstream. Most stroke cases are caused by plaque accumulation inside the blood vessel walls. This kind of condition is commonly known as stenosis. One of the methods for treating stenosis is using balloon angioplasty (BA) to revascularize the blockage area of plaque layers inside the vessels. Most ICAS rehabilitation devices are expensive because were imported from other countries. In order to reinforce the BA fabrication locally, we develop an in silico simulation program to represent the actual phenomenon physically during the stenosis treatment using BA. Thus, the result given will be a reliable recommendation for device fabrication.The BA deployment algorithm is virtually implemented using a spring-damper model analogy with the lineal spring approach. This approach allows obtaining physical information such as pressure along the blood vessel model. Thus, it can be evaluated regarding the standard clinical reference about blood vessel conditions. The simulation results were given in the meantime for 5 - 106 seconds, depending on the several parameters used. The pressure distribution of revascularized blood vessels was also obtained, assuming a uniform modulus of elasticity.
