Balloon

Improper deflation

Creates urine reservoir 

Catheter Tip

Biofilm formation

Urethral damage

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
