<p>A medical device for a biological lumen (10) comprises an outer tube body (18) which has a lumen (22) inside thereof, a blocking portion (72) which blocks the lumen (22) at a distal end of the outer tube body (18), and an inner structure (20) which has a port (80) that receives pressure from a priming liquid. The inner structure (20) is provided with an elastic member (86) proximal to the port (80). The elastic member (86) elastically deforms when the port (80) receives pressure from the priming liquid and causes the blocking portion (72) to distally move relative to the outer tube body (18).</p> |
