Patient Satisfaction

Significantly higher patient satisfaction with Dilapan-S®1

In a head-to-head trial with 419 pregnant women, patients were more satisfied with Dilapan-S® compared with Foley balloon in 3 domains (P<0.05).

Patients who received Dilapan-S® reported1:

  • Better sleep (P=0.01)
  • More relaxing time (P=0.001)
  • Ability to perform daily activities (P=0.001)

93% of patients described the comfort of insertion as fully acceptable3

ALMOST 80% of patients were able to sleep during cervical ripening3
Selected Important Safety Information

Patients should return to the physician for removal of Dilapan-S® at the indicated time and should be instructed not to attempt self-removal under any circumstances.
