Abstract: A scaffold is formed by several segments joined or connected to each other by only at least one coupling. The coupling decouples the segments in the axial direction over a finite distance of axial displacement. The scaffold when implanted in a peripheral vessel reduces loading on rings of a segment due to the decoupling of the segments in the axial direction over the finite distance.

Abstract: 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.

Abstract: A medical device includes a polymer scaffold crimped to a catheter having an expansion balloon. The scaffold has a structure that produces a low late lumen loss when implanted within a peripheral vessel and also exhibits a high axial fatigue life. In a preferred embodiment the scaffold forms ring structures interconnected by links, where a ring has 12 crowns and at most two links connecting adjacent rings.
