Abstract
An apparatus includes a delivery catheter having a deployable dynamic valve that dynamically opens and closes in response to relative fluid pressure thereabout, particularly while in an anatomical lumen. The valve is maintained in a collapsed configuration during introduction to a treatment site. The valve is adapted to automatically move from the collapsed configuration to a deployed configuration at the treatment site.
