A percutaneous, transluminal, angioplasty system includes a non-foreshortening stent and a stent anchor to hold the stent in place until delivery. The stent comprises rings and fused rings comprising various motifs such as butterfly or pinched ellipsoid motifs. Stent anchors can release the stent after an outer sheath uncovers the stent or uncovers the stent and biased or bent fingers of the stent anchors.
