摘要

A closure device for transcatheter operations comprises an easily foldable closure member with a shape-restoring force, an easily inflective fixing member of an elastic material, and an easily inflective elastic member having either ends respectively fixed to the fixing member or closure member and holding the closure member and the fixing member in close proximity one another. The closure device is used in combination with a catheter assembly comprising an elongated sheath opened at both ends and adapted to accommodate the folded closure device therein, and an operating member having at a distal end thereof a holding means for releasably holding the closure device and for guiding and protruding the folded closure device inserted in the sheath from a distal end of the sheath.
