ANATOMY INDEPENDENT DEFLECTOR

摘要

In general, the invention features an intra-vascular device (100) for filtering or deflecting emboli other large objects from entering a protected secondary vessel or vessels. The device of the invention may include a filter (201) to prevent a particle in a blood vessel from passing through the filter, a lateral structure (200) to hold the filter, and two wires (202, 203) attached the lateral structure, one each at its distal and proximal ends (206a, 206b). These wires may be used to control the deflection or orientation of the filter upon its installation within a blood vessel. Further, in some embodiments, these wires may be capable of readily detaching from the device, thus making it possible to install a filter without any significant appendages in a blood vessel.

主权项

1. A device for deflecting emboli, the device comprising:
a lateral structure circumscribing an elongate shape, a length of said lateral structure being between 80 mm and 120 mm and a width of said lateral structure being from 30 mm to 45 mm; a substantially planar, elongate filter attached to the length and width of said lateral structure; a first wire attached to the distal end of said lateral structure; and a second wire attached to the proximal end of said lateral structure;wherein said lateral support structure is sized such that upon installation of said device in the aortic arch of a human subject, it contacts the upper walls of said aortic arch.
