1. A clot retrieval device for removing clot from a blood vessel, the device having a collapsed delivery configuration and an expanded deployed configuration and comprising:

  • an elongate member extending between a proximal end and a distal end comprising a step-up feature;

    a first body comprising a proximal end and a distal end, the first body being configured for positioning within the blood vessel, wherein in the expanded deployed configuration the first body is configured to expand to form a tubular section, the first body having a proximally extending partial circumferential member disposed on the proximal end of the first body and about the distal end of the elongate member; and

    a second body comprising a proximal end and a distal end, the second body being configured for positioning within the blood vessel, wherein in the expanded deployed configuration the second body is configured to expand about the first body, the second body including a collar being eccentric to the distal end of the elongate member and disposed proximal of the step-up feature,wherein the collar is assembled over the partial circumferential member and elongate member to form a mechanical lock that prevents disassembly of the first body, the second body, and the elongate member under tension.
