A medical catheter for intravascular long-term infusion of medication by an implanted or extracorporeal dosage device characterized by the catheter tube being of a single or multi-layer elastomer having a distal end shaped such that the exit opening for the medication is laterally arranged axially offset relative to the distal end of the catheter. The catheter is also coated with an external protective layer composed of a hydrogel.

An apparatus for infusion of liquids into human or animal bodies which comprises a liquid reservoir having a reduced-pressure generating means associated therewith and an active delivery-dosing means, such as a roller pump, operationally coupled with the reservoir and with an outflow catheter having outflow opening within the body being infused. The reduced-pressure generating means, such as a volatile fluid, for example, a halogenated hydrocarbon, maintains a pressure at the point of connection between the reservoir and the active delivery-dosing means at a reference value which is lower than the pressure prevailing at the outflow opening of the outflow catheter.
