In vitro investigation of microcatheter behavior during microsphere injection in transarterial radioembolization

Objective: To investigate the behavior of a standard end-hole microcatheter during microsphere injection in a successively bifurcating phantom. A comparison between a clinical microcatheter and a rigid counterpart aims to unravel differences in microsphere distribution attributable to the flexibility and stability of the catheter tip during transarterial radioembolization (TARE). Hypothesis: It might be that under the influence of the pulsatile blood flow or injection, the radial position of the flexible catheter tip varies during microsphere injection. The collection contains the Solid work files, Excel files, Matlab scripts and SPSS files needed to reproduce the data presented in the article. Used software: Matlab R2022a (MathWorks, Natick, Massachusetts, USA), SPSS statistical software package version 26 (SPSS Inc. Chicago, IL, USA), SolidWorks 2023 SP5 (Dassault Systèmes SolidWorks Corp., Waltham, Massachusetts, USA)
