Vascular device for emboli removal having suspension strut and methods of use
First Claim
1. Apparatus suitable for filtering emboli comprising:
- an elongated member having a distal region having a longitudinal axis;
a support hoop;
a suspension member coupling the support hoop to the distal region so that the support hoop may be eccentrically laterally displaced relative to the longitudinal axis; and
a blood permeable sac affixed to the support hoop so that the support hoop forms a mouth of the blood permeable sac.

Abstract
Apparatus and methods are provided for use in filtering emboli from a vessel, wherein a vascular filter disposed on a guidewire, the vascular filter comprising 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 guidewire. 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 guidewire 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.

33. A method of filtering emboli from flow within a vessel comprising:
-
providing a vascular filter mounted on a distal region of an elongated member, the elongated member having a longitudinal axis, the vascular filter comprising a support hoop, a suspension member coupling the support hoop to the distal region and a blood permeable sac affixed to the support hoop;
inserting the distal region of the elongated member and the vascular filter into a vessel;
deploying the vascular filter within the vessel at a location at which the support hoop is eccentrically laterally displaced relative to the longitudinal axis and the support hoop forms a mouth of the blood permeable sac. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40)
