Magnetic-driven Multifunctional Optoelectronic Catheter for In Vivo Chemical Mapping and Precisely Guided Tumor Therapy

Traditional tumor treatment catheters have single function, low positioning accuracy and cannot realize real-time in-situ detection and integrated treatment. This research designs a miniature 2.5 mm-diameter magnetic-driven multifunctional optoelectronic catheter. The device integrates magnetic navigation, in-vivo chemical mapping, optical imaging and targeted tumor ablation functions. Relying on precise magnetic drive control, the catheter can accurately reach deep tumor lesions, realize real-time biochemical signal detection and lesion positioning, and complete minimally invasive precise tumor therapy in one step. It realizes the integration of diagnosis and treatment of deep tissue tumors, greatly improving the accuracy and safety of minimally invasive tumor intervention.
