Abstract
In general, the invention features an intravascular device, a delivery system, and methods for filtering or deflecting emboli or other large objects from entering a protected secondary vessel or vessels The intravascular device of the invention may prevent passage of a particle in a blood vessel from passing through a filter supported by a frame, upper and lower stabilizers, and a wire. The wire may be used to stabilize the device upon its deployment and installation within a blood vessel. Further, in some embodiments, the invention features a delivery system and methods for introduction of the device into a blood vessel.
Claims33
An intravascular device for deflecting emboli comprising:
- a. a frame having a length;
- b. an embolic filter attached to and extending the length of said frame;
- and
- wherein the device comprises a wire configured to run along a horizontal plane of the filter and exert a force on the frame and/or the filter when deployed in an aorta of a subject.
