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 innovative devices designed to provide temporary support to blood vessels. Unlike traditional stents, these stents gradually dissolve or are absorbed by the body after fulfilling their purpose of keeping the artery open. This minimizes long-term complications, such as chronic inflammation or late stent thrombosis, which can occur with permanent stents.
Attributes
- Material: Commonly made from polymers such as polylactic acid (PLA) or magnesium alloy.
- Design: Mesh-like tubular structure that offers temporary scaffolding to the artery.
- Dissolution Time: Typically designed to be absorbed over 1-3 years, depending on the material and specific product.
- Usage: Primarily used in coronary arteries but also explored for use in peripheral and other vascular regions.
- Diameter and Length: Available in various sizes to fit different artery diameters and lesion lengths.
- Flexibility and Radial Strength: Optimized to provide a balance between flexibility for navigation through arteries and radial strength to maintain artery patency until the vessel heals.
