| 摘要 |
A tubular stent for placement within a vessel of a living being includes one or more elongated wire-like members lying adjacent the inner wall of the tubular body of the stent and responsive to magnetic forces acting thereon to thrash about within the lumen formed by the stent body to dislodge accumulated sediments and/or fatty deposits. The wire member or members may be configured to lie adjacent the inner wall of the stent body except when excited by an apparatus comprising plural pairs of electromagnets which may be energized sequentially to generate a moving force field acting on the stent. |
