Abstract: A percutaneous transluminal angioplasty device includes a catheter defining one or more lumens. A filter is coupled to the catheter adjacent a distal end of the catheter, and the filter is movable between an unexpanded and expanded configuration via a filter activation wire that extends through a lumen. An expandable balloon is coupled to the catheter proximally of the filter, and a stent is disposed over at least a portion of the balloon. To deploy the stent to a target site, the filter is first moved into its expanded position via the filter activation wire. Then, the stent is expanded, and the balloon is inflated to expand the stent further radially. The balloon is then deflated, the filter is contracted, and the catheter, balloon, and filter are removed from the body.
