Abstract
A surgical device for opening a passageway adjacent a thrombus to allow both blood and medication to bypass a clot. The surgical device may also be used to pierce and remove a thrombus. The device includes a core element or wire having an expanding proximal cage assembly and a distal filter or expanding cage assembly placed around the core wire. Components of the device are preferably radio-opaque. The proximal end of the proximal cage may be affixed to an actuator to allow expansion of the cage after deployment. The proximal cage assembly may be used for collecting emboli or for displacing emboli to allow blood flow to resume, either with or without concurrent clot-dissolving drug treatment. The distal section is placed distally of the thrombus to collect portions of the thrombus which may loosen during the treatment or removal procedure.
