Abstract
An intravascular filter for capturing embolic particles entrained in blood flowing in an arterial vessel during an interventional procedure. The filter is intended to be used as a primary filtering device in conjunction with interventional treatment procedures such as balloon angioplasty and/or stenting. The filter may also be used as a secondary filtering device in conjunction with suction in atherectomy and other interventional procedures. The filter is capable of capturing embolic particles at least as small as 150 microns in diameter, thereby increasing the safety of balloon angioplasty and stenting. The filter includes a spring-like expandable strut assembly and a filtering medium composed of a plurality of complex passageways. The filter assembly is compressible to an initial low profile delivery diameter and is expandable to a larger deployed diameter.
