GRADUALLY SELF-EXPANDING STENT

摘要

A gradually self-expanding stent is provided with a plurality of stent cells. A restraining material is attached to the stent structure and restrains the stent structure from expanding to the expanded configuration. Over time the restraining material releases the stent structure to allow the stent structure to expand to the expanded diameter. An anti-thrombotic drug is incorporated into the restraining material.
