Angioplasty stent adapted to counter restenosis, respective kit and components

摘要

A stent structure includes a stent and one or more fibers disposed on the stent, the fiber adapted to provide a therapeutic agent. Nuclei containing therapeutic agents that impede restenosis may be included within the fiber or within separate particles that are contained within hollow core fibers. The fibers and the particles may be bioerodible. A permeable, biocompatible sheath may be interposed between the stent and the fiber. A kit including a stent, a fiber, and a delivery catheter is also described.
