Method of isolating the cerebral circulation during a cardiac procedure

摘要

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.

主权项

1. A method of isolating the cerebral circulation during a procedure, comprising the steps of:
advancing a catheter comprising a proximal sheath, an articulable distal sheat and a core member with a flexible coupler through the right subclavian artery, through the aorta, and into the left common carotid artery; opening a first filter within the brachiocephalic artery by proximally retracting the proximal sheath; articulating the articulable distal sheath and advancing a portion of the distal sheath into the left common carotid artery; opening a second filter within the left common carotid artery by advancing a core member carrying the distal filter through the distal sheath; and deflecting flexible coupler positioned within the left common carotid artery and proximal to the second filter and distal to a distal end of the articulable distal sheath.
