The present catheter employee a series of axial slits adjacent to its tip. The slits act to increase the flexibility of the catheter adjacent the tip thereby providing pressure relief in the event of blockage of the lumen at the tip. In addition, by forming the slits as slots, i.e. by removing material from the slits, it is possible to provide a catheter having flow through the sides adjacent to the tip for any desired purpose.
