What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only

Stopped early This study
Stopped early, before it reached the end. That can be for many reasons, including safety.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether using a special tube (EZ-Blocker) to collapse one lung during heart bypass surgery can reduce fluid buildup and the need for chest drains. The trial includes adults having planned coronary artery bypass surgery that uses the internal thoracic artery. The goal is to see if this technique leads to fewer breathing problems after surgery.

What this could mean

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

Active substance
EZ-Blocker
What this could lead to
If it works, this technique could reduce breathing complications and the need for chest tubes after bypass surgery.
What could go wrong
This is a small, early-stage study. The device may not reduce complications and could carry risks like airway injury or improper lung collapse.
