Abstract
An endovascular system includes inner and outer catheters, a handle system operably coupled one end of the catheters, and a microvalve coupled to the other end of the catheters. The microvalve is constrained in a radially-collapsed closed configuration for advancement within a vessel to a treatment site. The handle system is operable to displace the inner and outer catheters portions relative to each other to move the microvalve between closed and open configurations. An indicator is provided to visually indicate the extent by which the microvalve is opened within the vessel.
