New suction device aims to ease IUD insertion pain
NCT ID NCT07290517
First seen Jun 25, 2026 · Last updated Aug 14, 2026 · Updated 5 times
Summary
This study compares a new suction-based cervical stabilizer (Carevix) to the standard metal clamp (tenaculum) for IUD insertions. 100 women will be randomly assigned to one device, and they will rate their pain on a 0-10 scale. The goal is to see if the gentler suction tool causes less discomfort during the procedure.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Carevix suction-based cervical stabilizer device
- What this could lead to
- If it works, this could offer a less painful IUD insertion experience for women, especially those who have not given birth.
- What could go wrong
- This is a small, early-stage trial with only 100 participants, so results may not apply to everyone. The device is already FDA-approved, but pain reduction may be modest.
