The system, the device and the method of opening blockade venereal disease change

摘要

The system, the device and method in order to convert the efficiency of organization removal from body route maximally are offered. The system the device which opens blockade venereal disease change, has the guide wire which for example possesses rotary type aterekutomidebaisu or the blood vessel formation device, and the introduction due sir sheath. The guide wire introduction due sir sheath, when crossing blockade venereal disease change, assists the guide wire, it has the hyposulfite tube which possesses the cylindrical strength where is larger than cylindrical strength just of the guide wire profit, the sheath and the guide wire are movable in axial direction vis-a-vis each other. The sheath of the guide wire in the distal (2036) edge, furthermore being able to have the pliability which increases it increases pliability, and/or furthermore can have the soft distal (2036) point the operativity which passes by pulse tube structure easy it makes. The sheath makes profit, as for the guide wire of a smaller major diameter, can the guide wire of a smaller major diameter possible and make, a smaller major diameter possible in the device which next opens the blockade section.
