Apparatus and Methods for Occluding a Hallow Anatomical Structure
First Claim
1. A device for occluding a hollow anatomical structure, the device comprising:
- a clamp having at least first and second elongate clamping portions adapted to be placed on opposite sides of the hollow anatomical structure, said first and second elongate clamping portions respectively having ends coupled together with respective resilient urging members configured to urge at least one of said first and second elongate clamping portions toward the other of said first and second elongate clamping portions from an open position into a clamping position to occlude the hollow anatomical structure,said clamp comprising an annular shape configured to surround the hollow anatomical structure in the open position and a flattened shape in the clamping position configured to occlude the hollow interior of the hollow anatomical structure.

Abstract
A clamp (10) having at least first and second elongate clamping portions (2, 4) adapted to be placed on opposite sides of the hollow anatomical structure (40). The first and second elongate clamping portions (2, 4) respectively include ends coupled together with respective resilient urging members (6, 8) configured to urge at least one of the first and second elongate clamping portions (2, 4) toward the other of the first and second elongate clamping portions (2, 4) from an open position into a clamping position to occlude the hollow anatomical structure (40). The clamp (10) is shaped annularly such that it may surround the hollow anatomical structure (40) in the open position and reorient into a flattened shape in the clamping position to occlude the hollow interior of the hollow anatomical structure (40). Apparatus of the invention further include clamp delivery and actuation devices (80, 200) adapted to deploy the clamp (10).

19. Apparatus for occluding a hollow anatomical structure, the device comprising:
-
a clamp delivery and actuation device including first and second jaws, at least one of said first and second jaws configured to move toward and away from the other of said first and second jaws, and a clamp configured for attachment to said first and second jaws and having at least first and second elongate clamping portions adapted to be placed on opposite sides of the hollow anatomical structure, said first and second elongate clamping portions respectively having ends coupled together with respective resilient urging members configured to urge at least one of said first and second elongate clamping portions toward the other of said first and second elongate clamping portions from an open position into a clamping position to occlude the hollow anatomical structure, said clamp comprising an annular shape configured to surround the hollow anatomical structure in the open position and a flattened shape in the clamping position configured to occlude the hollow interior of the hollow anatomical structure. - View Dependent Claims (20, 21, 22)

23. A method of occluding a hollow anatomical structure with an annular clamp having at least first and second elongate clamping portions with opposite ends coupled together by respective resilient urging members, the method comprising:
-
holding the first and second elongate clamping portions a spaced apart orientation against a bias applied by the resilient urging members, surrounding the hollow anatomical structure with the annular clamp, and releasing the elongate clamping portions to move the first and second elongate clamping portions together against opposite sides of the hollow anatomical structure under the bias applied by the resilient urging members. - View Dependent Claims (24, 25, 26, 27)

28. A device for occluding a hollow anatomical structure, the device comprising:
-
a clamp having at least first and second elongate clamping portions adapted to be placed on opposite sides of the hollow anatomical structure, said first and second elongate clamping portions respectively having ends coupled together in a manner allowing at least one of said first and second elongate clamping portions to move toward the other of said first and second elongate clamping portions from an open position into a clamping position to occlude the hollow anatomical structure, said clamp comprising an annular shape configured to surround the hollow anatomical structure in the open position and a flattened shape in the clamping position configured to occlude the hollow interior of the hollow anatomical structure, and said elongate clamping portions further comprising generally parallel members capable of reorienting into at least first and second nonparallel relationships in the clamping position, said first nonparallel relationship comprising said elongate clamping portions converging toward one end of said clamp and said second nonparallel relationship comprising said elongate clamping portions converging toward an opposite end of said clamp.
