Bioabsorbable Stents:
- Also known as biodegradable or resorbable stents.
- Made from materials that dissolve or are absorbed by the body over time.
- Designed to provide temporary support to the blood vessel and then disappear.
Overview
Bioabsorbable stents, also known as biodegradable or resorbable stents, are designed to provide temporary support to blood vessels and then gradually dissolve or get absorbed by the body over time. These stents are intended to reduce long-term complications associated with permanent implants, such as chronic inflammation or late stent thrombosis.
Attributes
- **Material:** Typically made of polymers like polylactic acid (PLA) or magnesium alloy.
- **Design:** Mesh-like tubular structure that provides temporary scaffolding to the artery.
- **Dissolution Time:** Usually designed to be absorbed over 1-2 years.
- **Usage:** Primarily used in coronary arteries, but research is ongoing for use in other vascular regions.
- **Diameter and Length:** Available in various sizes to suit different artery diameters and lesion lengths.
- **Flexibility and Radial Strength:** Engineered for optimal balance between flexibility and radial strength during the period they remain in the body.
