  • a macrocoil thrombus engaging component having a length with a proximal end and a distal end, the length of the macrocoil comprised of microcoils that allow the length of the macrocoil to be extendable and flexible;

    a first wire capable of providing force on an end of the macrocoil;

    within the catheter are two sealing elements, a first forward-sealing element and a second rearward-sealing element that form a pressurable zone within the catheter;

    the first wire is a retraction wire for the first forward-sealing element;

    wherein upon removal from the catheter by force on at least the first forward-sealing element, the macrocoil expands and retains microcoils along a length of the macrocoil.
