ABSTRACT:
An expandable stent has a sheeted material which is expanded from a compacted configuration to an expanded configuration. The sheet is maintained in the compacted configuration at least in part by operation of a dynamic force, and the expansion occurs at least in part by removal of the dynamic force. In preferred embodiments, a biocompatible sheeted material is wrapped around a split reed grasper to produce a compacted configuration, and the split reed grasper is rotated to maintain the compacted configuration during insertion of the stent into a patient. The rotation is continued while the stent is positioned, and then the rotation is stopped or slowed to permit expansion of the sheet.
