Abstract
An apparatus includes a delivery catheter having a deployable dynamic valve that rapidly opens and closes in response to relative fluid pressure thereabout. The valve is maintained in a collapsed configuration during introduction to a treatment site. A balloon element is provided between the delivery catheter and the valve and is adapted such that upon inflation it can move the valve from the collapsed configuration to a deployed configuration.
