Catheter Blockage
Urethral damage
Bladder damage
Hole blockage
Catheter Tube
The Problem
Bladder Injuries
Tip of catheter damages bladder lining
Damaged epithelial lining encourages bacterial growth
Urethral Trauma
Friction during insertion damages urethral lining
Damaged lining promotes bacterial adherence
CAUTI
Bacteria growth occurs within the bladder and catheter
Encrustations from within the catheter, causing blockage
The Solution
Catheter Tube
Surface texturing to delay bacterial growth
Optimised tube diameter to decrease blockage
Catheter Tip
Reshaped to decrease urethral damage
Modified balloon position to stop bladder damage
