ABA TRI-BLOCK COPOLYMER AND BIORESORBABLE IMPLANTS MADE THEREWITH
A block copolymer comprises an A block and a B block. The A block provides mechanical strength while the B block provides elasticity to the polymeric material. The block copolymer may be an ABA tri-block copolymer. The A block may include one or more of polyglycolide (PGA), polylactic acid (PLA), or...

| description | A block copolymer comprises an A block and a B block. The A block provides mechanical strength while the B block provides elasticity to the polymeric material. The block copolymer may be an ABA tri-block copolymer. The A block may include one or more of polyglycolide (PGA), polylactic acid (PLA), or copolymer thereof. The B block may include a random copolymer of (i) glycolide (GA) and/or lactide (LA), (ii) trimethylene carbonate (TMC), and (iii) ε-caprolactone (CL). The block copolymer may cover an implantable device which may be used in delivering immediate hemostasis at a puncture site in a wall of a blood vessel. |
