|July 1, 1994
Summary
Flexible coil stents deployed in coronary angioplasty often achieve a smaller size than intended. Accurate stent sizing is crucial for preventing complications like thrombosis and restenosis after percutaneous transluminal coronary angioplasty.
Area of Science:
- Interventional Cardiology
- Biomedical Engineering
- Vascular Devices
Background:
- Flexible coil stents are used to manage acute or threatened closure after percutaneous transluminal coronary angioplasty (PTCA).
- Optimal stent sizing is critical for immediate procedural success and reducing risks of acute thrombosis and restenosis.
- The actual in vivo deployment size of flexible coil stents at nominal pressures was not previously evaluated.
