Discover a new approach to labour induction

Product overview

Dilapan-S® is an osmotic hygroscopic dilator produced from a patented Aquacryl® hydrogel that guarantees consistency of action.

It is a rigid gel rod that increases in volume by absorbing fluids from the cervical canal, so it gradually dilates the cervix.

The thin 4 mm rod can expand up to 15 mm over a 12–24 hours period. This allows it to dilate and soften the cervix gradually. Usually a set of 3–5 rods is used to ripen your cervix sufficiently and make you ready for your labour.

Simultaneously, Dilapan-S® initiates endogenous prostaglandin release causing collagen degradation which softens the cervix.

Dilapan-S® is sterilized by irradiation. It is manufactured in an ISO 13485. Certified facility and is CE Certified under the Medical Device Directive (93/42/EEC). Approved by FDA for sale in the United States.

Induction of labour

In the absence of a ripe or favourable cervix, a successful vaginal birth is less likely. Therefore, cervical ripening is mandatory before labour is initiated.

Dilapan-S® is a perfect device with a unique combination of benefits − efficacy, safety and patient satisfaction for induction of labour.

Other Indications

Dilapan-S® can be used everywhere, where we need to examine the uterine cavity:

− prior to pregnancy termination or induced abortion in both 1st and 2nd trimester

− preparation of cervix prior to fetal demise or hysteroscopy

− cervical preparation prior to the insertion or removal of intrauterine device

− for difficult embryo transfer

Mode of Action


Achieved cervical dilation dependingon lenght of     DILAPAN-S insertion

Dilapan-S, Graph active part dimensio 4mm / 3 mm

The dilator increases in volume by absorbing fluids from cervical canal.

  • Mechanical:
    Controlled pressure on the cervical wall, which dilates the cervix
  • Biophysical:
    Partial and reversible osmotic cells dehydration, which softens the tissue of the cervix
  • Physiological:
    Promotion of endogenous prostaglandins, causing collagen degradation and tissue restructuring

Made of patented hydrogel AQUACRYL® − guaranteed consistency of action.
Dilapan-S® rods do not contain any active substances, which could be released during its use.
