<p>A haematuria catheter has a main drainage lumen (10), which is closed at the patient end tip (15) of the catheter and opens through drainage openings (16, 18 and 19) just rearwardly of the tip and forwardly of an inflatable balloon (22) by which the catheter is secured in the bladder. An inflation lumen (11), extending in an internally projecting rib (13), opens into the balloon (22) and is sealed closed by a plug (17) at one of the drainage openings (16). An irrigation lumen (12) along a second rib (14) extends beyond the drainage openings and opens through an opening (21) at the tip of the catheter so that irrigation liquid emerges from the catheter at a point spaced from the drainage openings.</p> |
