1. A removable stent for placement within a lumen comprising:
- a scaffolding of struts configured to define a substantially cylindrical member having a proximal end and a distal end; and
at least one element intertwined about at least a portion of the struts, wherein the element comprises at least one engageable member such that a force applied to the engageable member does not result in purse-stringing.

Abstract
A removable stent for placement within a lumen is provided. The stent includes a scaffolding of struts configured to define a substantially cylindrical member having a proximal end and a distal end. The stent also includes at least one flexible element spirally wound along at least a portion of a respective strut, wherein the element comprises at least one engageable member such that a force applied to the engageable member does not result in purse-stringing.

11. A removable stent for placement within a lumen comprising:
-
a scaffolding of struts configured to define a substantially cylindrical member having a proximal end and a distal end; and a plurality of engageable members arranged circumferentially about at least one of the proximal and distal ends; and at least one element disposed within each of the engageable members and about the circumference of the proximal or distal end, wherein a force applied to the element at the proximal or distal end causes the proximal or distal end to reduce in diameter. - View Dependent Claims (12, 13, 14, 15, 16)
