Embodiment Construction
[0042] Hereinafter, an embodiment in which the present invention is embodied will be described with reference to the drawings. In this embodiment, a suction catheter for sucking thrombus is embodied. figure 1 It is a schematic overall side view showing the structure of the suction catheter.
[0043] Such as figure 1 As shown, the suction catheter 10 is formed to have a length of 1 m to 2 m, and includes a catheter body 11 and a cannula 12 attached to the proximal end (base end) of the catheter body 11 . The catheter main body 11 includes a suction tube 14 and a wire guide tube 15 provided on the distal end side of the suction tube 14, and the respective tubes 14, 15 are formed by fusion bonding. The suction tube 14 has a suction lumen 17 inside it, and the guide wire tube 15 has a guide wire lumen 18 (referring to figure 2 and image 3 ).
[0044] The cannula 12 has a fluid passage 12a inside it that communicates with the suction lumen 17 of the suction tube 14 . A syring...
