TRANSLUMINAL ANGIOPLASTY DEVICES AND METHODS OF USE

摘要

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.

主权项

1. A percutaneous transluminal angioplasty device, comprising:
a multi-lumen catheter having a proximal end and a distal end, the catheter defining a first lumen, a second lumen, and a third lumen, each lumen extending through at least a portion of the catheter; a filter disposed adjacent the distal end of the catheter, the filter being movable between unexpanded and expanded configuration; an expandable balloon disposed between the filter and the distal end of the catheter; and a stent extending over at least a portion of the expandable balloon.
