An encased stent that discourages restenosis by having a homogenous
endothelial cell lining along the inner wall of the stent. The
endothelial cell lining may be coated on the stent before the stent is
placed in the artery, or the endothelial cell lining may be grown after
placement by several factors that encourage such growth and discourage
restenosis. The endothelial cells to coat the stent may be genetically
modified to enhance the growth of the endothelial cells into a
homogeneous lining. The stent has a continuous lining in the form of a
multi-layer polymer coating, including a conducting biocorrosion
inhibiting layer and a continuous film of polyurethane coupled by a
coupling agent to polyethylene glycol. Various drugs and cell factors may
be incorporated into the lining, such as anti-thrombin, anti-inflammatory
and anti-coagulant drugs, cell cycle inhibitors, and vascular endothelial
growth factors.
