PROBLEM TO BE SOLVED: To provide a closing plug for operation by a catheter having a simple shape, capable of being easily operated, capable of safely and reliably closing a small hole, capable of being easily recovered and hardly sticking a thrombus and a catheter assembly to insert this into the operation part. SOLUTION: A closing plug contains a blocking-up member 1 being easily collapsible and having shape restoring force, a fixing member 2 to fix this blocking-up member 1 to a tissue around a defective hole and a spring elastic member 3 having both ends respectively fixed to the fixing member 2 and the blocking-up member 1 and holding the blocking-up member 1 and the fixing member 2 in a closely adjacent state. The closing plug introduced into the operation part blocks up the defective hole by sandwiching a tissue around the defective hole by the blocking-up member 1 and the fixing member 2. |
