Abstract
A method is provided for infusing a therapeutic. The method includes providing a microvalve device having an inner catheter longitudinally displaceable relative to an outer catheter, and a filter valve coupled to the inner catheter adjacent the distal ends of the inner and outer catheters such that longitudinal displacement of the inner catheter relative to the outer catheter permits the filter valve to be reconfigured from a first configuration to a second configuration. The filter valve is advanced to a target location in via a blood vessel in which the filter valve is configured under tension. Then in an embodiment, the tension is released and the filter valve is placed under compression. Then the therapeutic agent is infused through the inner catheter and out of the orifice of the inner catheter beyond the filter valve.
