Abstract
An embolic protection device or system for use in a lumen of a vessel in a patient's vascular system. The device filters debris and blood clots in a body lumen and/or prevents them from moving distally from a treatment site in a vessel and causing emboli. The device may include a filter placed distally of the treatment site. The device may include an occlusive element placed either distally or proximally of the treatment site.
