1. A heat transfer device for low temperature ablation of tissue, said heat transfer device comprising:

  • first and second elongated segments, one of said first or second elongated segments providing a closed end of said heat transfer device;

    a bellows structure connecting said first and second elongated segments, said bellows structure being structured to be less thermally conductive than said first and second elongated segments by virtue of inherent fluid stagnation on the surface of said bellows structure; and

    a tubular conduit disposed within and extending substantially through said first and second elongated segments, said conduit having an inner lumen for transporting a working fluid to a distal end of said one of said first or second elongated segments providing a closed end of said heat transfer device.
