Abstract
An implantable flow adjuster (20) includes proximal and distal support rings (22, 24) which support a flow adjuster panel (26). The flow adjuster panel (26) divides the lumen through the device (20) into two sections, one of reducing cross sectional area and the other of increasing of increasing cross sectional area. The two sections (40, 42) cause, respectively, an increase in blood pressure and blood flow and a decrease in blood pressure and blood flow. These result is a pressure differential beyond the distal end of the device (20). This pressure differential can be used to divert blood flow away from the neck (14) into an aneurysm (12), thus to reduce pressure and wall sheer stress within the aneurysm in order to assist in the repair of the vessel.
