PROBLEM TO BE SOLVED: To provide a medical implement introducing device whereby an inserting operation is facilitated to shorten a work time, the enlargement of an inserting port is reduced to easily stop bleeding after an operation and insertion is enabled even in a comparatively narrow part. SOLUTION: The medical implement introducing device 10 is constituted of a sheath 11 where a synthetic resin tube 12 having an inner diameter which enables inserting medical implement such as a catheter is adopted as a mainbody and an inserting port part 12a having a seal means for preventing the flow-out of body fluids is provided in the base end part and of a dilator 15 where a shape memory alloy tube 16 having an outer diameter to be inserted into the sheath 11, its tip 18 is formed to be a piercing possible shape and also length is the one to be projected from the tip of the sheath 11 is adopted as the mainbody. A slit 19 can be provided in the tip part of the shape memory alloy tube 16 so as to have flexibility. |
