Abstract:In this paper a concept origami-based, magnetic, surgical capsule robot for the purpose of aneurysm coiling is proposed. The design is intended to be an alternative to simple coiling, which is a minimally invasive procedure to treat aneurysms by filling them with platinum coils via a catheter. Unlike simple coiling, the origami-based magnetic capsule closes the aneurysm with a single rigid structure. Furthermore, the capsule is transported and deployed using magnetic actuation, eliminating the need for catheters. This subsequently ensures better closure of the aneurysm and a less invasive treatment. After a full analysis of the design, it is concluded that the capsule can only be used to treat aneurysms with sizes of approximately 5 mm or smaller. Aneurysms at these sizes have a low chance of rupture, causing the capsule to be more appropriate as a preventive treatment. In this way, smaller aneurysms can be treated before they become a threat to the patient’s health. In addition, it was examined whether the required magnetic field strength and gradient for the magnetic actuation had attainable/ realistic values. This turned out not to be the case, but with several suggested adjustments these values could be brought to suitable levels. To show that it is possible to have a capsule unfold magnetically, a paper prototype was tested. The result of the prototype confirms that the described unfolding technique can indeed be used.
