Abstract

Catheter comprising a flexible and elastic, pipe-like body part (1, 11), the internal canal of which is connected to the bladder of the patient through one or several body orifices and, furthermore, with a bellow-shaped distal section (1a) located at the outlet of the patient's bladder when the catheter is in use, which fixes the catheter position, and an opposite, bellow-shaped proximal section (1c) which prevents the slipping in of the catheter; where in default case the diameter of both distal section (1a) and proximal section (1c) exceeds that of the outlet of the bladder but, stretched out horizontally, it is smaller than the diameter of the urethra and reduces to approximately the size of the below-shaped intermediate section (1b) connecting distal and proximal sections (1a, 1c), thereby allowing to introduce the catheter through the urethra until distal section (Ia) is located inside the bladder and, following the termination of the axial pulling pressure, sections (1a, 1b, 1c) revert to their original size, and thanks to its bellow shape, intermediate section (1b) flexibly adjusts to the size and shape changes ever and, furthermore, with a closing device designed in distal section (1a), made up by flexible membrane valve (13) openable by manual deformation, located at the external end of proximal section (1c).
