The tandem pessary is made of two cubes of flexible silicone coupled to each other. It can be stored at room temperature from 1 to 30 °C protected from UV radiation without contact to reactive media, gas, ozone or mineral oil.
Since the introduction of the product, the models have been continuously improved.
A detailed updated clinical evaluation can be found under Downloads / Clinical Evaluation.
Patients with grade 3-4 uterine or vaginal vault prolapse may be treated with the tandem pessary, even if ring-shaped or single cube pessaries may not hold the prolapse. The reduction of the prolapse may not be possible if the vagina cannot retain a single cube pessary. Similar to the cube pessary, the vacuum effect of the concave surface achieves a good adhesion, whereby the non-perforated version provides a better adhesion but is more difficult to handle by the patient. In addition, the tandem pessary can be useful in case of stress incontinence whereby the lower cube takes on the supporting function of the urethra and the upper cube mainly assures the adhesion of the pessary.
The maximal uninterrupted period of application is 30 days. It is recommended that the patient changes the pessary herself, thereby she should remove it every evening and insert it in the morning. The patient should be trained about application, change by healthcare professionals whereby additional treatments (e.g. cremes) should be discussed.
The product must not be used by other patients. Before each insertion the surface of the pessary must be inspected. In case of any damage the pessary must be exchanged. Tandem pessaries must be inserted with thread towards the vagina. The pessary may be cleaned by running water without using any disinfectant.
