1. A nested mechanical thrombectomy assembly deliverable as a single assembled unit comprising:
an outermost mechanical thrombectomy device actuatable from a radially compressed state to a radially expanded state; the outermost mechanical thrombectomy device forming an inner channel extending in an axial direction;
a proximal shaft having a lumen extending in an axial direction therethrough; a distal end of the proximal shaft is connected to a proximal end of the outermost mechanical thrombectomy device such that the inner channel is in communication with the lumen of the proximal shaft;
at least one inner mechanical thrombectomy device actuatable from a radially compressed state to a radially expanded state; while in the radially compressed state, the at least one inner mechanical thrombectomy device is disposed in the inner channel of the outermost mechanical thrombectomy device; and
a wire extending through the lumen of the proximal shaft and connected to a proximal end of the at least one inner mechanical thrombectomy device;
wherein each of the outermost mechanical thrombectomy device and the at least one inner mechanical thrombectomy device is actuatable independently of one another.
