Researchers help confirm value of flow-diverting device for most challenging aneurysms

Ringer and his colleagues are using the flow-diversion device to treat three types of brain aneurysms:

  • Saccular or berry, which have a neck at their origin on the main artery and a dome that can expand like a balloon.
  • Wide-necked or fusiform, which do not have a defined neck.
  • Giant, which are more than 2.5 centimeters in diameter.

Standard treatments for brain aneurysms include a surgical procedure called clipping, in which the surgeon opens the skull and places a clip over the aneurysm's neck, and a less invasive, endovascular procedure called coiling, in which the surgeon uses a catheter to deliver and deposit tiny coils into the aneurysm. Another endovascular procedure involves filling the aneurysm with a special glue that hardens.

Wide-necked and giant aneurysms have proven resistant to these treatments, however, because they have no necks that can be clipped and because coils or glue tend not to remain within the aneurysms' open mouths.

The flow-diverting device addresses this problem through the placement of a stent-like scaffold over the healthy artery outside the aneurysm. The scaffold is a tiny braided mesh cylinder, 10 to 35 millimeters long, which is made of platinum and nickel-cobalt alloy.

"When using this treatment we never go inside the aneurysm," Ringer said. "The tightly woven tube creates resistance to the blood flow, causing the blood to continue down the artery along the path of least resistance, causing the aneurysm to eventually clot off, wither and die."

Unlike clipping and coiling procedures, which neutralize blood flow to an aneurysm almost immediately, a flow-diversion device may require weeks or months to neutralize an aneurysm. "But the advantage of the Pipeline is that we don't have to work inside the aneurysm," Ringer said. "And therefore, if the shape, size, or configuration of the aneurysm is such that both surgery and coil
