Occlusion catheter for cerebral artery treatment and treatment method using it

摘要

An occlusion catheter for use during therapeutic intervention of a blood vessel for flushing away debris indluding an elongated guide catheter (20) sized to be introduced into the blood vessel, an occlusion balloon (12) located at or near the distal end of the catheter and an inflation lumen (18) integral with the guide catheter and communicating with the interior of the balloon enabling the balloon to be inflated to form a seal between the balloon and the blood vessel wall. The balloon is capable of being expanded to at least 5 times its deflated diameter when inflated.
