FIG 5. A, Graph shows IAP change during balloon inflation. Note significant increase of IAP with complete balloon inflation with or without saline flush.

B, Angiogram of experimental aneurysm created on the common carotid artery of a swine.

C, Approximately 80% occlusion of the aneurysm was achieved with combination of Onyx and a microballoon.

D, Embolization of the remnant at the inflow zone using nearly complete occlusion technique. Note small space between balloon and distal portion of the aneurysmal neck (arrow).

E, Example of successful occlusion of the aneurysm with Onyx and balloon technique. Note small concave shape of the Onyx along with balloon shape.
