The Incontinence Ring pessary is for the treatment of Stress Urinary Incontinence (SUI).
The Incontinence Ring has a much thinner ring thickness than the Ring with Knob, due to the fact it has an inner metal band that helps maintain rigidity of the Incontinence Ring.
The Incontinence Ring does not have a supporting membrane.
NB. The Incontinence Ring contains an inner metal component.
