Abstract
A bioabsorbable blend comprising poly(L-lactide) (PLLA) and a phosphorylcholine group-containing copolymer (PPCP) capable of enduring the mechanical strength of blood vessel walls and applicable for fabricating cardiovascular devices was developed. The blend acts as a scaffold to support blood vessel walls during vascular healing and undergoes biodegradation in vivo after vascular healing is complete. Furthermore, the blend can prevent the formation and adsorption of thrombi.
