Abstract: A catheter for use in a urine collection system has a hollow tube forming a suprapubic section (1), a bladder section (2) and a urethral section (3). There are drainage holes in the bladder section (2) and optionally either or both of an abdominal stop (5) and a non-return cuff (6) on the bladder section (2) which holds the catheter in place. There may also be a valved drainage section (31) extruding from the suprapubic section (1) to a drainage outlet (32), or a urine collection bag (35). The drainage section (31) and/or the suprapubic section (1) may have a pH sensor therein. There may also be a urine collection container (12) connected to the suprapubic section (1) the connection forming a closed valve-free fluid flowpath from the bladder section to the urine collection container and from the urine collection container to the bladder section, whereby the urine collection container provides a low pressure reservoir.

Abstract: A suprapubic urethral catheter has a hollow tube with a suprapubic section (1), a bladder section (2) and a urethral section (3). An abdominal stop (5) is slidably mounted on the suprapubic section (1), and the bladder section (2) has drainage eyeholes (4) which enable urine from the bladder to drain into the catheter. A non-return cuff (6) is mounted on the bladder section between the drainage eyeholes (4) and the abdominal stop, the non-return cuff (6) having a projecting portion projecting outwards from the tube, being deformable towards the tube and resisting deformation away from the tube. The cuff (6) allows the catheter to be inserted into a suprapubic track in the abdominal wall of a user, but once the cuff has entered the bladder, the projecting portion prevents retrograde movement of the catheter out of the suprapubic track.

Abstract: The invention provide suprapubic urethral catheters which preferably consist of a tube having a suprapubic end portion (1) which in use will be located suprapubically in the user, a bladder segment (2) into which in use urine can enter and will be located within the bladder of the user, and a urethral segment (3) distally of the suprapubic end portion which in use will be located within the urethra of the user, the urethral segment (3) including a distensible segment (5) which distends outwardly under pressure within the bladder of the user and is thereby urged into sealing engagement with the interior of the urethra of the user.
