1. An angioplasty device, comprising:
a multi-lumen catheter having a proximal portion and a distal portion, the catheter defining a first lumen, a second lumen, and a third lumen each extending through at least a portion of the catheter;
a filter disposed on the catheter and being movable between an unexpanded configuration and an expanded configuration, the filter comprising a filter frame formed of a shape memory material having a memory of the unexpanded configuration;
a filter activation wire coupled to the filter frame and extending through at least a portion of the first lumen, wherein tensioning the filter activation wire urges the filter from the unexpanded configuration to the expanded configuration;
an expandable balloon disposed on the catheter and spaced apart from the filter;
a self-expanding stent extending over at least a portion of the expandable balloon;
a movable sheath extending over at least a portion of the self-expanding stent;
a sheath wire coupled to the movable sheath and extending through at least a portion of the second lumen, wherein movement of the sheath wire translates the sheath axially; and
a guidewire configured for extending through at least a portion of the third lumen, wherein the third lumen is in communication with the second lumen.
