ABSTRACT:
A catheter for the injection of a fluid, for example, medicine, into body cavities such as veins or other hollow organs is provided with a head which is insertable into the body cavity and includes hollow needles movably disposed therein between retracted and extended positions and with an operating mechanism mounted to the end of the catheter opposite the head and operatively connected to the needles for moving their front ends outwardly in contact with the walls of the body cavity for supplying the fluid or medicine through the hollow needles directly to the wall portions of the body cavities to be treated. A balloon may be disposed in front of the catheter head and may be inflated or deflated by way of a passage extending through the catheter.
