| 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 ). |
