1. A temporary device for capturing embolic material from a bodily fluid within a vessel of a patient, the device comprising:

  • an elongate guidewire having a distal region;

    a capture element disposed about the guidewire distal region, the capture element having distal and proximal ends and a central region, wherein relative longitudinal movement between the distal and proximal ends accompanies a transformation of the capture element between a generally tubular closed configuration and a deployed configuration wherein the central region is expanded into apposition with the vessel; and

    at least one latch fixed to the guidewire distal region in a location such that the latch is operable to releasably engage with the proximal end of the capture element to temporarily retain the capture element in the deployed configuration.
