Researchers at the Polytechnique Montréal Nanorobotics Laboratory in Canada have
developed a new method to guide endovascular instruments into complex vascular
structures that were hitherto inaccessible to endovascular surgeons. The
technique involves moving the patient and the endovascular instrument using a robotic platform within a magnetic field.
Endovascular
surgery has enabled minimally invasive approaches for a huge array of surgical
interventions. However, the technique
is not without its challenges, and advancing a thin catheter through long and
tortuous vasculature can be difficult, with the device potentially getting
stuck. In fact, certain areas of the body are inaccessible to endovascular
surgeons because of the complexity of their vasculature and the impossibility
of advancing a catheter through it using conventional means.
