Abstract
Abstract A constriction device that constricts body tissue is viewable under X ray fluoroscopy. 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 Analysis
Total Claims: 22
Claim 1
Independent Claim
82 words
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
Independent Claim
82 words
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 3
Dependent Claim
37 words
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 4
Dependent Claim
26 words
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 5
Dependent Claim
26 words
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 6
Dependent Claim
21 words
The method of claim 1 , wherein the drawing the body tissue into the sleeve step is performed with vacuum assistance.
Claim 7
Dependent Claim
25 words
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 8
Dependent Claim
25 words
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 9
Independent Claim
80 words
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 10
Independent Claim
80 words
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 11
Dependent Claim
30 words
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 12
Dependent Claim
21 words
The method of claim 8 , further comprising the step of verifying the placement of the sleeve through X ray fluoroscopy.
Claim 13
Dependent Claim
28 words
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 14
Dependent Claim
25 words
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 15
Dependent Claim
31 words
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 16
Dependent Claim
17 words
The method of claim 8 , wherein the expanding the sleeve step is performed with vacuum assistance.
Claim 17
Dependent Claim
23 words
The method of claim 8 , wherein the providing a resilient hollow sleeve step comprises providing a resilient hollow sleeve containing radiopaque material.
Claim 18
Dependent Claim
27 words
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 19
Dependent Claim
23 words
The method of claim 15 , wherein the providitig a resilient hollow sleeve step comprises providing a resilient hollow sleeve containing radiopaque strips.
Claim 20
Dependent Claim
18 words
The method of claim 8 , further comprising the step of securing the sleeve onto the body organ.
Claim 21
Dependent Claim
26 words
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 22
Dependent Claim
29 words
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.
