A snare particularly desirable for removing retrograde wires from blood vessels includes a rail wire attached to an inflatable/collapsible balloon of biocompatible semi-compliant resilient plastic material in a “fixed wire” configuration, or the balloon has a “rapid exchange” or “over-the-wire” lumen upon which the balloon may ride along a separate guide wire already in place. An additional lumen or cavity is defined by or within the balloon allowing the capture of objects, such as retrograde wires, within the lumen or cavity when the balloon is deflated. Desirably a central lumen is defined by biocompatible semi-compliant plastic material, or the balloon has a pair of arms so that a bridge wire extending between the pair of arms defines a cavity which can receive objects. An object for repositioning or removal is captured by the gripping action of the balloon assembly alone, without need for the utilization of a conventional snare.
