This relates to restoring recoil or maintaining compression of an emphysematous or otherwise unhealthy lung and includes elastic members (13) which contract or compresse the lung tissue (20). The elastic member (13) is secured to tissue of the lung (20) either inside or outside of the lung to supplement the natural elasticity of the lung or maintain the tissue in a compressed state. The elastic member may include elastic patches (18), elastic bands (13), coil springs (16), covers or a combination of these elements.
