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

1. A constriction device that constricts body tissue comprising an elongated sleeve, the sleeve including opposed opened ends and being formed from expandable 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 being visible under X ray fluoroscopy.

2. The device of claim 1 wherein the sleeve further includes an outer surface and a coating of X ray opaque material on the outer surface to form the portion of the sleeve visible under X ray fluoroscopy.

3. The device of claim 2 wherein the sleeve has a longitudinal dimension between the opposed opened ends and wherein the coating of X ray opaque material comprises strips of X ray opaque material along the longitudinal dimension of the sleeve.

4. The device of claim 1 wherein the sleeve includes a side wall extending between the opposed opened ends and X ray opaque material embedded in the side wall to form the portion of the sleeve visible under X ray fluoroscopy.

5. The device of claim 4 wherein the side wall defines a longitudinal dimension of the sleeve, and wherein the X ray opaque material comprises strips of X ray opaque material embedded in the side wall along the longitudinal dimension of the sleeve.

6. The device of claim 1 wherein the sleeve further includes an inner surface and X ray opaque material on the inner surface to form the portion of the sleeve visible under X ray fluoroscopy.

7. The device of claim 6 wherein the sleeve has a longitudinal dimension between the opposed opened ends and wherein the X ray opaque material comprises strips of X ray opaque material along the longitudinal dimension of the sleeve.

8. The device of claim 1 wherein the sleeve includes a plurality of X ray opaque elements to form the portion of the sleeve visible under X ray fluoroscopy.

9. The device of claim 8 wherein the X ray opaque elements are adjacent to one of the opposed openings.

10. The device of claim 8 wherein the X ray opaque elements are arranged in a side-by-side relation.

11. The device of claim 8 wherein the sleeve includes an inner surface and wherein the X ray opaque elements are on the inner surface of the sleeve.

12. The device of claim 11 wherein the X ray opaque elements are adhered to the inner surface of the sleeve.

13. The device of claim 11 wherein the X ray opaque elements are adjacent to one of the opposed openings.

14. A constriction device that constricts body tissue comprising sleeve means including opposed opened ends and formed from expandable 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, and X ray opaque means to render the device visible under X ray fluoroscopy.
