Abstract
Body lumens such as blood vessels are selectively occluded by mechanically collapsing the blood vessel and subsequently applying energy or other occlusive conditions within or adjacent the collapsed region. For example, vessel collapsing mechanisms can include spreadable opposed elements, reciprocating jaw mechanisms having penetrating elements, and devices for applying negative pressure to collapse the blood vessel. One or more electrodes can be used in a monopolar or bipolar fashion to apply radiofrequency or other energy to the body lumen in the region where it has been collapsed.
