AtTerm Medical has been developing a device to prevent preterm birth.

The OBSPRING is a device that is positioned around the uterine cervix and behaves like a shock absorber.

It allows transient shortening and dilation of the cervix during contractions, restoring the cervix to its initial state when contractions subside.OBSPRING maintains the natural resistance of the cervix, thus helping to prevent preterm birth.

The small, disposable device is inserted by the physician during an outpatient visit and removed at term.
