A catheter for temporary introduction into body cavities and adapted for one-time use, said catheter being made of a soft, highly flexible, and high-molecular material such as plastic, latex, or the like and a physiologically compatible external stiffening coating of gelatine thereon to provide temporary sufficient stiffness to the catheter in order to facilitate insertion of the catheter into a body cavity, said gelatine coating being soluble in body fluids, said gelatine coating providing sufficient stiffness to the catheter to enable the catheter to be readily inserted in a body cavity, said gelatine coating dissolving in said cavity to thereby expose said soft, high-flexible, and high-molecular material to thereby provide indwelling comfort over extended periods of time until withdrawn.
