1. A system for constricting body tissue, comprising: a resilient elongated hollow sleeve having opposed open ends, the sleeve comprising a radiopaque material such that at least a portion of the sleeve, when implanted, is visible through an external imaging device, and the sleeve being expandable to an expanded configuration so as to permit application to a portion of a body organ when in the expanded configuration and being collapsible to a less expanded configuration after application to the body organ portion, thus permitting collapse of the body organ portion such that substantially no flow of air or fluid passes through the body organ portion; a means for expanding at least a portion of the sleeve; and a delivery device for delivering the sleeve to the desired body organ, the delivery device having a first portion configured to support the sleeve in an expanded position and to permit body tissue to be drawn therein.
