How Dilapan-S® works

Dilapan-S® is composed of Aquacryl®, a firm, synthetic, patented hydrogel1,2:

Diagram showing visual change in product over the course of 24 hours

The rod expands to several times its original diameter through absorption of moisture from the cervix

Approximately 80% of rod expansion occurs within the first 4-6 hours after insertion

Instruct patient to return at the indicated time. Dilapan-S® should not be left in for more than 24 hours.

Make Dilapan-S® your standard of care for cervical ripening1,2

Dilapan-S® has multiple modes of action2,3

After insertion, Dilapan-S® initiates a cascade of biophysical, mechanical and physiological changes in the cervical tissue that continue until rod removal.2,3


Dehydration of cervical tissue
  • Dilapan-S® rods are inserted into the cervical canal, where they absorb moisture from the cervix


Radial pressure caused by rod expansion
  • The Dilapan-S® rods expand, exerting controlled radial pressure on the cervical canal, which dilates the cervix


Prostaglandin release and collagen reorganization
  • Stretching of the cervical tissue promotes the release of local endogenous prostaglandins
  • Local prostaglandins initiate collagen degradation and cervical softening and ripening

The cervix gradually and predictably softens and dilates, preparing the mother for the next step in induction of labor.2,3
