1. A passive modification device comprising:
an elongated body extending along a first axis, wherein the elongated body comprises a shape memory alloy with a threshold contraction along the first axis at a threshold temperature;
a passageway extending along a second axis different from the first axis, wherein the passageway is shaped to surround a cable extending along the second axis;
a first modifying structure on a first portion of the passageway; and
a second modifying structure on a second portion of the passageway opposite the first modifying structure;
wherein the first modifying structure is connected to a first end of the elongated body and the second modifying structure is connected to a second end of the elongated body; and
wherein contraction of the elongated body causes the first modifying structure and the second modifying structure to move towards each other, wherein movement of at least one of the first modifying structure or the second modifying structures is configured to permanently modify the cable.
