Title: DEVICES AND METHODS FOR PREVENTING PRETERM BIRTH
Abstract:
A pessary and associated methods for preventing a preterm birth includes a pessary body having a first end and a second end offset from one another. The first end defines a first opening that is configured to receive a cervix. The pessary body has an exterior wall that extends from the first end towards the second end. The exterior wall has an outer surface, and an inner surface opposite the outer surface, the inner surface enclosing a channel that extends between the first and second ends and that is in fluid communication with the first opening. The pessary body further has an interface surface that extends between the first end and the second end. The interface surface is configured to engage the cervix so as to secure the pessary to the cervix.
