A composition is provided comprising an amino acid terminated polyester having a predetermined monomeric sequence comprising at least one amine and at least three monomeric units derived from at least one hydroxyacid.
Such a polyester can be prepared by the stepwise addition of at least three monomeric hydroxyacid units to an amino acid monomeric unit.
A medical device is also provided which is made in whole or in part of an amino acid terminated polyester having a predetermined monomeric sequence.
