摘要： PROBLEM TO BE SOLVED: To provide a fluid type thrombectomy catheter which extirpates the thrombus from the human blood vessel passed into a bent pipeline existing in the brittle blood vessel or from another celom. SOLUTION: The fluid type thrombectomy catheter is provided with an external catheter having a hollow part and an internal high-pressure tube dimensioned to allow the passage through the hollow part of the catheter. The distal side end of the internal high-pressure tube extends beyond the distal side end of the catheter and carries a jet cap for orienting one or more jets of brine heading the proximal end side toward the distal side end of the catheter. The catheter has a stationary stopping member which is arranged on the terminal end side and directed inward. The internal high-pressure tube has a movable stopping member which is arranged on the distal side and directed outward, engages with the inward directed stationary stopping member, and thereby positions a jet cap at a specific distance from the distal side end of the catheter.
