| titleOfInvention | catheter |
| abstract | The present invention provides a catheter capable of administering a drug solution by pushing a slit open without being damaged by an increase in internal pressure due to liquid feeding, while the tip portion is sufficiently flexible. The catheter of the present invention has a constant outer diameter constant portion along the longitudinal direction of the outer diameter, and a tapered portion whose inner diameter and outer diameter gradually decrease toward the distal end on the distal end side of the constant outer diameter portion. A catheter body is provided. The tapered portion is provided with a plurality of slits extending to the distal end thereof, and the proximal end of the slit is located on the distal end side of the catheter body from the position where the inner diameter of the tapered portion starts to gradually decrease. As a result, the flexibility of the distal end portion of the catheter can be ensured, and even when the internal pressure of the catheter increases due to the liquid feeding, the liquid can be fed satisfactorily. Further, by optimizing the position of the slit, it is possible to prevent the drug solution from diffusing and to administer the drug solution in the target direction and position.
