Abstract
Abstract A process and apparatus for occluding a vascular site. A catheter having a highly distensible occlusion balloon detachably mounted at a distal end thereof is provided to the vascular site and at least partially filled with an aqueous balloon inflation fluid which allows the balloon placement to be imaged. The balloon is porous to the aqueous inflation fluid and the inflation fluid is gradually displaced through the balloon pores by a liquid filling composition which is solidifiable on contact with the aqueous inflation fluid to produce a mass to which the balloon is nonporous. The filing composition is injected to bring the balloon wall into contact with the vessel wall at the vascular site. The balloon is detached from the catheter after the filling composition has at least substantially solidified and the catheter removed from the body.
