Abstract

Endovascular techniques play a significant role in the management of cerebral AVMs. Currently, flow-guided microcatheters are used for the transfemoral embolization of intracranial AVMs. These catheters are carried by blood flow from their initial position in the neck into the intracranial circulation to the point of greatest flow, which is usually into the feeders of the AVM. Despite this state-of-the-art technology, a significant limitation includes difficulty reaching inaccessible branches secondary to suboptimal placement of the microcatheter. In this report we describe a new device concept to overcome the current limitations of low-guided transfemoral embolization of cerebral AVMs. It involves a magnetic surgery system (MSS) that magnetically manipulates the tip of the microcatheter. The feasibility of this concept was successfully tested using multiple transparent glass intracranial vascular models of the anterior cerebral circulation.
