The device includes an elongated sleeve. The sleeve includes opposed opened ends and is formed from expandable or elastic material to receive therein, when in an expanded condition, body tissue to be constricted and to constrict the body tissue therein when released from the expanded condition. At least a portion of the sleeve includes X ray opaque material rendering the device visible under X ray fluoroscopy. ## Claims ### Claim 1 A method of suppressing leakage from a body tissue, the method comprising the steps of: providing a sleeve formed from an expandable material and having opposed open ends, the sleeve being dimensioned for constricting the body tissue to suppress flow of at least one of body fluid and air through the body tissue, and including an X ray opaque material visible under X ray fluoroscopy; drawing the body tissue into the sleeve; and constricting and collapsing the body tissue within the sleeve. ### Claim 2 (depends on 1) The method of claim 1, further comprising the step of resecting a portion of the body tissue by severing the sleeve between its opposed open ends after the drawing the body tissue into the sleeve step. ### Claim 3 (depends on 1) The method of claim 1, further comprising the step of confirming the collapse of the body tissue by fluoroscopically visualizing the X ray opaque material. ### Claim 4 (depends on 1) The method of claim 1, wherein the drawing the body tissue into the sleeve step comprises drawing a portion of a lung into the sleeve. ### Claim 5 (depends on 1) The method of claim 1, wherein the drawing the body tissue into the sleeve step is performed with vacuum assistance. ### Claim 6 (depends on 1) The method of claim 1, further comprising the step of expanding the sleeve prior to the drawing the body tissue into the sleeve step. ### Claim 7 (depends on 1) The method of claim 1, further comprising the step of confirming that the sleeve is in the desired position by viewing the sleeve fluoroscopically. ### Claim 8 A method of suppressing fluid flow through a portion of a body organ, the method comprising the steps of: providing a resilient elongate hollow sleeve, the sleeve having at least a portion thereof configured to be viewable through an external imaging technique; expanding the sleeve to an expanded configuration; drawing a portion of the body organ into the expanded sleeve; releasing the sleeve from its expanded configuration such that the sleeve collapses the portion of the body organ disposed therein. ### Claim 9 (depends on 8) The method of claim 8, further comprising the step of confirming that there is substantially no fluid flow through the portion of the body organ disposed within the sleeve. ### Claim 10 (depends on 8) The method of claim 8, further comprising the step of verifying the placement of the sleeve through X ray fluoroscopy. ### Claim 11 (depends on 8) The method of claim 8, further comprising the step of resecting a portion of the body organ by severing the sleeve and the body organ disposed therein. ### Claim 12 (depends on 8) The method of claim 8, wherein the drawing a portion of the body organ in the expanded sleeve step is performed with vacuum assistance. ### Claim 13 (depends on 8) The method of claim 8, wherein the drawing a portion of the body organ into the expanded sleeve step comprises drawing a portion of a lung into the expanded sleeve. ### Claim 14 (depends on 8) The method of claim 8, wherein the expanding the sleeve step is performed with vacuum assistance. ### Claim 15 (depends on 8) The method of claim 8, wherein the providing a resilient hollow sleeve step comprises providing a resilient hollow sleeve containing radiopaque material. ### Claim 16 (depends on 15) The method of claim 15, wherein the providing a resilient hollow sleeve step comprises providing a resilient hollow sleeve containing radiopaque spheres embedded into the sleeve. ### Claim 17 (depends on 15) The method of claim 15, wherein the providitig a resilient hollow sleeve step comprises providing a resilient hollow sleeve containing radiopaque strips. ### Claim 18 (depends on 8) The method of claim 8, further comprising the step of securing the sleeve onto the body organ. ### Claim 19 (depends on 15) The method of claim 15, wherein the step of securing the sleeve onto the body organ is performed by inwardly facing projections on the sleeve. ### Claim 20 (depends on 19) The method of claim 19, wherein the step of securing the sleeve onto the body organ takes place automatically as the sleeve is released from its expanded configuration.
