ABSTRACT:
A catheter or similar device, particularly a female transient urinary catheter (1), comprises a rigid polypropylene tube having a saw tooth formation (4) providing a flexible region which separates a handle portion (2) from an insertion portion (3). In the insertion portion are formed apertures (6, 9) in the distal tip of the catheter and in the side of the catheter (1) towards the distal end. The tip aperture (6) has a rolled over edge (7) and the side apertures (9) are formed in recesses (8) in the external profile of the catheter. A scaling portion (10) comprises a sinusoidal undulation in the catheter wall which effects an improved seal between the catheter and the wall of the urethra.
