Abstract
A balloon catheter assembly including a balloon and a catheter. The catheter has a chuck and a multi-tube unit including at least an inner tube and an outer tube arranged slidably and coaxially with the inner tube. The balloon is removably fixed to the distal portion of the inner tube by the chuck which is pulled into the outer tube to be closed, and which is extended from the outer tube to be opened. The catheter is introduced to a required dwelling portion in a blood vessel by a tubular guide sheath having an inner diameter such that the guide sheath admits the catheter, and the expanded balloon is left in the dwelling portion to occlude the blood vessel.
