Figure 5. Magnetic navigation and angioplasty demonstration of the MBF. (A) The MBF successfully navigates complex and tortuous cerebral arteries such as the Circle of Willis (CW), right internal carotid artery (ICA), and right middle cerebral artery (MCA) in a 3D cerebrovascular phantom; (B) Magnetic navigation of the MBF in an ex vivo porcine placenta; (C) Phase-change expansion of the MBF via microwave heating. MBF: Magnetic balloon fiberbot; 3D: three-dimensional.
