Summary

Researchers at Massachusetts General Hospital are testing a new device that goes through the nose to take pictures of the small intestine. The study includes 30 healthy adults and pregnant women in their second trimester. The goal is to see if people can tolerate the device and if it can clearly show gut features, which might lead to easier diagnosis of digestive diseases.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: TNIB Catheter (imaging device)
What this could lead to: If successful, this could lead to a less invasive way to diagnose gastrointestinal diseases.
What could go wrong: This is a very early feasibility study with only 30 participants, so results may not apply broadly. The device may cause discomfort or fail to visualize features.
