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.

Abstract: An implantable stent includes a plurality of rings. At least a distal end ring has an eased corner feature formed in the polymer substrate at a radially outward, distal-facing corner of the ring while relatively sharp corners of the polymer substrate are maintained in radially inward corners of the ring.

Abstract: Methods of treating a diseased blood vessel exhibiting stenosis with a bioabsorbable stent are disclosed. The implanted stent supports the section of the vessel at an increased diameter for a period of time to allow the vessel to heal. The stent loses radial strength sufficient to support the section of the vessel in less than 6 months after implantation, loses mechanical integrity, and then erodes away from the section. The biodegradable stent results in changes in properties of plaque with time as the stent degrades. The time-dependent properties include the luminal area of the plaque and plaque geometric morphology parameters.
