How Mara

The Mara Water Vapor Ablation System is
redefining endometrial ablation.

By gently filling the uterine cavity with
naturally expansive water vapor, Mara treats
more women with varying uterine anatomies*,
does not require general anesthesia, and
most importantly, safely and effectively
reduces heavy menstrual bleeding.3

*Cavity lengths greater than 10cm (up to 12cm),
cavities with certain types of myomas up to 4cm,
and the presence of Essure®

Endometrial Ablation Using Natural Water Vapor

The Mara Water Vapor Probe is inserted through the cervix.
Three balloons gently inflate to seal the uterus and secure the Mara Water Vapor Probe. Mara's proprietary double pre-procedure safety assessment ensures correct probe positioning and uterine cavity integrity. Uterine cavity safety tests are completed before water vapor treatment begins.
Endometrial water vapor ablation is carried out with a treatment time of 2 minutes. This includes automated real-time cervical temperature and intrauterine pressure monitoring.
The balloons deflate at the end of the treatment, and the Mara Water Vapor Probe is removed.
