Abstract

In the realm of endovascular procedures, which are fundamental for treating vascular issues, practitioners employ various tools such as guidewires, catheters, and therapeutic devices. Access points, notably the femoral and radial arteries, play a crucial role in navigating these devices. Radial access has shown promise in reducing adverse events compared to femoral access. However, a recurring challenge in such interventions is herniation, where devices lose access around bends, leading to non-target branches. To address this, this project seeks to introduce criteria for herniation and a formula based on the theory of minimum potential energy. In solving the problem of herniation, flexural rigidities of the endovascular devices are necessary for the math, but there is no robust database of device flexural rigidities, and no existing apparatus designed and built for the express purpose of measuring these long, slender devices at various points along their lengths.
