First Claim
1. An embolic filter assembly, said filter assembly comprising:
- at least one strand of wire forming a support hoop;
the strand of wire extending from said support hoop and forming at least one suspension strut;
the suspension strut coupled, at least in part, to a guide wire or a filter wire or a tube; and
a blood permeable sac having an opening, said opening fixedly attached to the support hoop, thereby forming a proximal opening or mouth of the embolic filter.

Abstract
Apparatus and methods are provided for use in filtering emboli from a vessel, wherein a vascular filter is disposed on a guide wire, the vascular filter having a support hoop disposed from a suspension strut so as to permit lateral eccentric displacement of the support hoop relative to a longitudinal axis of the guide wire. A blood permeable sac is affixed to the support hoop to form a mouth of the blood permeable sac. The support hoop is disposed obliquely relative to the guide wire and is capable of being properly used in a wide range of vessel diameters. The support hoop collapses the mouth of the blood permeable sac during removal of the vascular filter to prevent material from escaping from the sac. A delivery sheath and introducer sheath for use with the vascular filter of the present invention are also provided.
