Abstract

In a catheter for the supply of liquid into a body region which comprises a small tube of plastic material, the tube wall has, in the region to be inserted in the body, perforations in the form of point punctures. These punctures are normally closed due to the elasticity of the wall material and open to let liquid through when the internal pressure in the tube considerably exceeds the pressure outside the tube.
