Method for Surgical Treatment of Occlusive Disease
First Claim
1. A method for surgically treating an occluded intraluminal tissue, comprising:
- (a) positioning a retractable intraluminal medical device at an appropriate intraluminal tissue location, said intraluminal medical device comprising a one-piece sheath which defines a generally tubular body;
said sheath having a central longitudinal axis;
said sheath having at least one stable initial collapsed state and at least one stable deployed expanded state;
said sheath in at least one stable initial collapsed state having a plurality of portions having an equal radius of curvature which project inward into said central longitudinal axis;
an attachable, re-attachable, and detachable retractor comprised of a plurality of rigid connected prongs, forks, or stems, or combinations thereof;
said retractor having a plurality of rigid attachable segments;
said retractor being mechanically attachable to and mechanically re-attachable to said sheath along a plurality of longitudinal indentations along said sheath;
said retractor being mechanically detachable from said sheath;
said retractor acting on said sheath whereby movement of said attachable segments of said retractor against said sheath in a stable initial collapsed state causes said sheath to elastically or semi-elastically expand radially from said collapsed state to a stable deployed expanded state;
said retractor acting on said sheath whereby movement of said attachable segments of said retractor against said sheath in a stable deployed expanded state causes said sheath to collapse radially from said stable deployed expanded state to a collapsed state;
(b) elastically or semi-elastically radially expanding said sheath from a stable initial collapsed state to a stable deployed expanded state using said retractor;
(c) mechanically radially collapsing said sheath from said stable deployed expanded state to a collapsed state using said retractor.

Abstract
A method of surgically treating occlusive disease in an intraluminal tissue using both a retractor (6) and a retractable one-piece stent. The stent is constructed and arranged such that it can exist in at least a stable initial collapsed state (12) and a stable deployed expanded state (10). In conjunction with the retractor, the stent is positioned at an appropriate location within an occluded intraluminal tissue and converted from a stable initial collapsed state to a stable deployed expanded state, and is then converted to a collapsed state and removed before significant restenosis occurs.
