1. A thin film device comprising a seamless thin-film expanse (i) formed of a sputtered nitinol shape memory alloy;

  • (ii) defining, in an austenitic state, an open, interior volume;

    (iii) having a thickness between 0.5-100 microns;

    (iv) having an austentite finish temperature Af below 37°

    C.; and

    (v) demonstrating a stress/strain recovery greater than 3% at 37°

    C.;

    where the expanse can be deformed into a substantially compacted configuration in a martensitic state, and the expanse assumes, in its austenitic state, a shape defining such open, interior volume.
