Zusammenfassung:	An injection catheter including a catheter stem, a cathetertip, and a bundle of injection needles, wherein either the catheter tip is axially displaceable r elative to the catheter shaft or the catheter tip is fixedly connected to the catheter stem and the bundle of injection needles is longitudinally displaceable relative to the cathet er tip. The catheter tip may take various forms, as the injection needles within the catheter ste m may take various forms and may be guided in various ways. An operating device is pro vided for effecting relative movements between the injection needles and the catheter tip, which operating device comprises two parts that are controllably displaceable rela tive to one another, thereby to cause the injection needles to be exposed or retracted. The operating device also includes inlets allowing medication to be applied through the in jection needles.
