Abstract: An apparatus for use in a therapeutic medical procedure that may include an elongate sheath having a longitudinal axis, an outer surface a distal end and a proximal end, the elongate sheath having a first lumen having a first cross-sectional area running from an first opening at the distal end to a first point proximal the distal end and a second lumen fluidly connected to the first lumen, the second lumen having a distal end at or proximal the first point and a second cross-sectional area less than the first cross-sectional area, the second lumen having a portion running generally along the elongate axis; and an elongate member having a first portion having a third cross-sectional area, a proximal end and a distal end and having a therapeutic device disposed on the elongate member proximate the distal end, the therapeutic device having a first configuration having a fourth cross-sectional area, wherein the elongate member is disposed in the first and second lumens and the distal protection device is disposed

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.
