BLOOD VESSEL EXPANDER, INTRODUCER, GUIDE WIRE, AND MEDICAL INSTRUMENT GUIDE DEVICE

摘要

PROBLEM TO BE SOLVED: To perform manual operation for inserting a medical instrument in a blood vessel quickly and precisely.

SOLUTION: The blood vessel expander 1 includes: a main body part 2 in the long shape which is inserted in the blood vessel; and a taper-shaped expansion part 3 formed on the tip side in the insertion direction of the main body part 2. A liquid flow path 4 is formed so that the liquid reaches the expansion part 3 from a distal end side of the main body part 2. A liquid discharge port 5 linked to the liquid flow path 4 is opened to an outer surface of the expansion part 3. The liquid is poured into the liquid flow path 4 and discharged into the blood vessel from the liquid discharge port 5.
