Vascular device for emboli and thrombi removal 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 filter frame disposed on the elongated member, the filter frame having a hoop portion at least partially forming a filter mouth and an elongate portion extending longitudinally from the hoop portion at a first region that is an articulation region and at a second region spaced apart from the first region;
a polymeric blood permeable sac affixed to the hoop portion so that the filter mouth is a proximally facing mouth of the blood permeable sac;
wherein the elongate portion of the filter fame extends distal from the hoop portion to provide support for the blood permeable sac; and
wherein the elongate portion is substantially U shaped, having a first portion extending longitudinally separated from a second portion extending longitudinally by a curved portion.

Abstract
Apparatus and methods are provided for use in filtering emboli from a vessel and/or performing thrombectomy and embolectomy, wherein a vascular device disposed on a guidewire includes a support hoop disposed from a suspension strut. Alternately, a support hoop having an articulation region may be directly connected to a region proximate the distal end 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 longitudinal axis of the guidewire and is capable of being properly used in a wide range of vessel diameters. The vascular device collapses during removal to prevent material from escaping from the sac. A delivery sheath and introducer sheath for use with the vascular device of the present invention are also provided.
