| Abstract: | Despite the benefits of Minimally Invasive Surgery (MIS) over open surgery, MIS is not omnipresent due to multiple technical challenges. Thus easier methods of MIS are being developed. Applying this technology to the arteries is not possible. This thesis aims to develop an origami-based and magnetically actuated device that could assist endovascular MIS. The MIS selected was the endovascular repair (EVAR) of Abdominal Aortic Aneurysms (AAA). Three concepts were developed, which, after evaluation, resulted in a final concept utilizing three modules to move through an artery. Based on the requirements, the waterbomb tesselation and the collapsable tower were integrated into the final design. A prototype of each separate module was developed to gain insight into the behaviour of the module, and a prototype of the entire system was created. The prototypes were made by glueing PLA panels and neodymium magnets to paper with perforation lines that followed the required crease pattern’s folding lines. The total system prototype provides promising evidence as a valid proof of principle, as it can locomote through a tube at a speed of up to 8.3 mm/s and expand radially by up to 30%. The design is not yet ready for endovascular applications. |
