ABSTRACT:
A catheter intended to be inserted in a body duct, vessel or cavity in order to maintain the passage of liquid, gas or solid substances.
The catheter (1) is made of plastic. The catheter (1) is characterized in that it is provided with an outer casing (2-5), which entirely or partially covers the cathether (1) and consists of a hydrophilic plastic substance capable of absorbing liquid and thereby to increase its volume, i.e. to swell, so that the catheter (1) maintains its position after its insertion into a body duct, vessel or cavity.
