Interventional Neuroradiology

Interventional Neuroradiology

Neuroendovascular therapy uses medical imaging techniques to diagnose and treat diseases of the central nervous system, head, neck, and spine. Very fine plastic catheters and tiny instruments are guided through the arteries and veins to treat conditions such as strokes, aneurysms, tumors of the head or neck, and abnormal malformations. This treatment circumvents the need for traditional open surgery, lowering risks, hospital stays, and total recovery time.

An aneurysm is a weakening of an artery wall that creates a bulge that can rupture and cause internal bleeding, possibly resulting in stroke, brain damage, and even death if not treated immediately. This can be treated by endovascular coiling, where a catheter is inserted through an artery to the aneurysm to block blood flow by injecting coils that ultimately close off the aneurysm.

Yet delivering one coil after another is a complicated task, where the interventional neuroradiologist needs to maneuver the catheter’s tip all around the sac to enclose the entire space. In this rabbit-model, a large bifurcation aneurysm was treated using Bendit. All coils were injected at one time, framing the entire sac in one go.

Bendit technology is a game changer in the fantastic voyage of vascular access and navigation
