BIOABSORBABLE IMPLANTS

摘要

A bioabsorbable implant including an elongated metallic element having more than 50% by weight a metal and being substantially free of rare earth elements, the elongated metallic element defining at least a portion of the bioabsorbable implant and including a wire formed into a discrete bioabsorbable expandable metal ring; at least two biostable ring elements, each biostable ring element having a biostable and radio-opaque metallic alloy, the bioabsorbable expandable metal ring being disposed adjacent to at least one of the biostable ring elements; at least one flexible longitudinal connecter including a bioabsorbable polymer, the connector being disposed between at least two adjacent rings; and a coating having at least one pharmaceutically active agent disposed over at least a portion of one ring.
