Bioabsorbable polymeric composition for a medical device
A crystallized bioabsorbable polymer scaffold comprises a polymer composition of poly (L-lactide-co-tri-methylene-carbonate) or poly (D-lactide-co-tri-methylene-carbonate) or poly (L-lactide-co-ε-caprolactone) or poly (D-lactide-co-ε-caprolactone) in the form of block copolymers of blocky copolymers, wherein the scaffold is cold-bendable.
1. A bioabsorbable composition comprising a crystalline polymer composition, the polymer composition comprising: a poly (L-lactide) moiety, and/or a poly (D-lactide) moiety, and/or poly L-lactide-co-PEG moiety, and/or poly D-lactide-co-PEG moiety, linked or admixed with poly (L-lactide-co-Tri-methylene-carbonate) or poly (D-lactide-co-tri-methylene-carbonate) or poly (L-lactide-co-ε-caprolactone) or poly (D-lactide-co-ε-caprolactone) in the form of block copolymers or blocky random copolymers.
2. The bioabsorbable composition of claim 1 , further comprising a pharmaceutical agent.
3. The bioabsorbable composition of claim 2 , wherein the pharmaceutical agent comprises tacrolimus, sirolimus, everolimus, rapamycin, or mixtures thereof.
4. The bioabsorbable composition of claim 2 , wherein the pharmaceutical agent comprises a drug which inhibits smooth muscle cell migration and/or proliferation.
5. The bioabsorbable composition of claim 1 , wherein the polymer composition comprises poly (L-lactide), linked or admixed with poly (L-lactide-co-ε-caprolactone) in the form of block copolymers or blocky random copolymers.
6. A crystalline polymer composition, comprising: a poly (L-lactide) moiety, and/or a poly (D-lactide) moiety, and/or poly L-lactide-co-PEG moiety, and/or poly D-lactide-co-PEG moiety, linked or admixed with poly (L-lactide-co-Tri-methylene-carbonate) or poly (D-lactide-co-tri-methylene-carbonate) or poly (L-lactide-co-ε-caprolactone) or poly (D-lactide-co-ε-caprolactone) in the form of block copolymers or blocky random copolymers.
