Embodiment 1
[0072]Embodiment 1 of the present invention provides an intravascular transport device, such asfigure 1 As shown, a transport conduit 1 and a sheath 22 are included, and the transport conduit 1 is used in conjunction with the sheath 2. The sheath 2 is composed of a sheath handle 7, a sheath tube 8, and a developing ring 5 in order; the sheath body 8 distal retardation can be coordinated with the guide wire to reduce the pair during transport Vascular damage. The delivery conduit 1 is composed of a transport catheter handle 3, a transport catheter body 4, a developing ring 5, and a sealing valve 6. Such asFigure 10 As shown, the transport conduit 4 is provided with an extended segment 11, and the extended segment 11 is provided in the distal end of the delivery catheter body 4, which allows the transport conduit to body 4 distal end telescopic variables, easier to enter the coronary and nervous system. Striosis blood vessels. A cross slit is provided on the top of the sealing valve 6...
