1. A maceration system, comprising:

  • a macerator wire comprising a distal end consisting of a loop, the loop configured to collapse upon placement thereof within introduction element and to re-expand upon removal thereof from the introduction element and to break up or macerate clots or blockages within a subject'"'"'s body by rotational movement; and

    a rooter configured to engage and manually spin the macerator wire, the rooter including;

    a cylindrical housing with an elongated slot extending longitudinally along a length of the cylindrical housing;

    a rotatable element within an interior of the cylindrical housing, the rotatable element including a rotation facilitator;

    an actuator including;

    a cylindrical element residing within the cylindrical housing and surrounding the rotatable element, the cylindrical element configured to complementarily engage the rotation facilitator of the rotatable element to cause the rotatable element to rotate as the cylindrical element is translated along at least a portion of a length of the rotatable element;

    an intermediate portion extending from the cylindrical element of the actuator and through the elongated slot of the cylindrical housing; and

    an external element secured to the intermediate portion of the actuator outside of the cylindrical housing, the external element including a trigger protruding from the cylindrical housing, the trigger configured to receive at least one digit of a hand of an individual, to be translated along the length of the cylindrical housing by the at least one digit, to translate the intermediate portion of the actuator along the elongated slot of the cylindrical housing and to translate the cylindrical element of the actuator along at least a portion of the length of the cylindrical housing;

    a conduit extending through the length of the rotatable element and communicating with both a distal end of the rooter and a proximal end of the rooter, the conduit configured to receive a portion of the macerator wire;

    a coupling feature associated with the rotatable element, the coupling feature configured to engage the macerator wire in a manner that enables the rooter to spin the macerator wire during or separately from longitudinal movement of the macerator wire.
