IMPLANTABLE FLOW ADJUSTER

摘要

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.

1. An endoluminal flow adjuster having a diameter, a length delimited by proximal and distal ends, and providing a passage for the flow of fluid therethrough;
the flow adjuster including at least one support structure providing proximal and distal supports spaced in a longitudinal direction of the flow adjuster between the proximal and distal ends; and an adjuster element including a panel having a length extending in the longitudinal direction, said panel being disposed between and supported by the proximal and distal supports, the panel dividing the passage through the flow adjuster into first and second parts varying in size over at least a part of the length of the flow adjuster.
