US Patent 8080053 Stent, stent removal and repositioning device, and associated methods

A removable stent for placement within a lumen is provided. The stent includes a scaffolding of struts formed from a tube of memory material and having a proximal end, a distal end, and an interior region. The stent includes at least two flexible elements independently secured to the scaffolding and spaced circumferentially from one another. Each element defines an engageable member such that an inwardly directed force applied to the engageable members reduces a diameter of the scaffolding.
