ABSTRACT:
An angioplasty device is disclosed comprising a woven tube of metal or plastic fibers and a retraction stylet that are attached at one end to a catheter tube for insertion into a vein, artery and the like for the removal of plaque and similar material. One or more guide wires or a stylet may be attached to the woven tube for rotation and manipulation inside the artery. When the stylet or guide wires are retracted, the woven tube expands and contacts the interior, plaque-coated wall of the artery. Movement of the guide wires and expanded woven tube will abrade atherosclerotic plaque from the artery to form particles which are trapped within the tube. An expandable fabric within the woven tube which opens and closes with the corresponding expansion and closure of the woven tube may be used to collect the trapped particles. Removal of the angioplasty device from the artery will them remove the atherosclerotic particles from the patient.
