Abstract
The invention is a catheter with a fluid flow divider positioned near the distal end of the catheter for dividing a first lumen into two channels at a point where a second lumen branches from the first lumen, and for selectively perfusing the branch lumen. The invention is particularly suited for use in the aortic arch. The fluid flow divider may comprise one or more inflatable chambers or one or more deployable shrouds comprising a plurality of arms with a webbing extending between adjacent arms. The inflatable chambers may be relatively noncompliant or they may be compliant, exhibiting elastic behavior after initial inflation, to closely fit the aortic lumen size and curvature. The catheter may further include one or more additional or auxiliary flow control members located upstream or downstream from the fluid flow divider to further segment the patient's circulatory system for selective perfusion to different organ systems within the body or to assist in anchoring the catheter in a desired position.
