  • (a) an outer sleeve;

    (b) an inner strap in slidable engagement with the outer sleeve, wherein prior to contacting the outer sleeve to the body part, at least a portion of the inner strap is anchored to the outer sleeve;

    (c) a windlass connected to the inner strap, wherein the windlass isadapted to be rotated such that when the windlass is rotated a portion of the inner strap is twisted, shortening an effective length of the inner strap; and

    (d) a restraining mechanism connected to the outer sleeve, the restraining mechanism adapted for receiving an end of the outer sleeve;

    wherein the inner strap forms a continuous loop extending from a first end of the outer sleeve to at least the windlass and back to the first end of the outer sleeve; and

    wherein a radial compressive force is applied to the body part upon applying a tensile force to the inner strap by rotating the windlass, wherein the radial compressive force restricts the flow of blood in the body part.
