A Navigation Console to Steer Magnetic Instruments Under Radiological Guidance for Neuro-Vascular Interventions

EasyChair Preprint 8157

Abstract

The gold-standard for treating some neurovascular diseases such as ischemic stroke is an effective and minimal invasive endovascular technique. The primary instruments used are catheters and guidewires that are inserted into the vasculature through a small incision at the groin. Some instruments have a curved tip allowing for easier access of different vessels as they bifurcate and are navigated by pushing, pulling, and rotating. In cerebrovascular interventions, interventional neuroradiologists are often faced with tortuous and complex anatomies that can be challenging to navigate and require a high level of skill and expertise. An alternative to manual catheter and guidewires is a robotic approach using robotic magnetic navigation (RMN). In robotic magnetic navigation RMN, magnetic instruments composed of a flexible magnetic tip are redirected by the external magnetic field generated by a magnetic navigation system (MNS). In this work, we propose a new interface that allows the steering of magnetic instruments without the need of additional visual feedback other than the already available 2D fluoroscope image. The interface is intuitive and promises a shallow learning curve for new adopters, good catheter and guidewire control, improving patient safety, and simple integration in the operating room infrastructure.
