Abstract

Single filter and multi-filter endolumenal methods and systems for filtering fluids within the body. In some embodiments a blood filtering system captures and removes particulates dislodged or generated during a surgical procedure and circulating in a patient'"'"'s vasculature. In some embodiments a filter system protects the cerebral vasculature during a cardiac valve repair or replacement procedure.

Claims

1. A single filter embolic protection device, for positioning in the aorta, comprising:

a first elongate, tubular body, having a proximal end, a distal end and a central lumen extending therethrough;

a second tubular body, extending through the central lumen; and

a filter assembly carried by the second tubular body,

wherein the filter assembly is configured to appose a catheter-based device passing between the filter assembly and a vessel wall to prevent substantially all debris from flowing past the filter assembly.

2. The single filter embolic protection device of claim 1, wherein the filter assembly comprises an inflatable annulus.

3. The single filter embolic protection device of claim 1, wherein the filter assembly comprises a channel through which the catheter-based device may pass.

4. The single filter embolic protection device of claim 1, wherein the filter assembly comprises a plurality of filter lobes.

5. The single filter embolic protection device of claim 1, further comprising a strut member connecting the second tubular body to the filter assembly.
