1. A method of performing an angioplasty comprising:
advancing a catheter to a site of a vascular stenosis;
disposing an integrated filter assembly within a blood vessel downstream of the vascular stenosis;
disposing a stent radially inward of the vascular stenosis;
tensioning an activation wire using a first actuation knob on a proximal handle, thereby deploying the filter assembly;
tensioning a sheath wire using a second actuation knob on the proximal handle, thereby moving a sheath proximally to expose the stent,
allowing the stent to expand against the vascular stenosis;
post-dilatating the stent using a balloon;
deflating the balloon;
contracting the filter assembly; and
removing the catheter from the body.
