NCT ID NCT07373353
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new device called AMJ-401 in 50 people with ischemic heart disease (blocked heart arteries) in Japan. Participants receive the device during a standard procedure to open blocked arteries. The main goals are to check for acute strut fractures right after the procedure and to see how well the device is covered by tissue after 6 months. This is an early-stage trial focused on safety and device performance.

What this could lead to
If successful, this device could improve outcomes for patients with blocked heart arteries by reducing complications like strut fractures.
