    摘要: 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).

    摘要: Described herein are various methods and apparatuses for delivering stents and other devices into the myocardium of a patient. One preferred stent delivery system provides access to the insertion site in the myocardium by advancing a delivery catheter through a blockage in a coronary artery, or around the blockage through a coronary vein or through a channel or tunnel formed around the blockage. In one embodiment, once the distal end of the delivery catheter is adjacent the myocardium, an angled bend is created in the catheter by actuating expandable steering guides mounted to the catheter which cooperate with the walls of the blood vessel to cause the catheter to turn. Then, a guidewire is advanced through the delivery catheter and into the myocardium. In another embodiment, a tip-deflecting pull wire extends from the distal end of the delivery catheter which may be actuated to turn towards and then inserted into the myocardium. In another embodiment, an exit port facing the insertion site is provided within the catheter or a balloon mounted on the catheter so that a guidewire may be directed through a lumen and out the exit port into the myocardium. Once the guidewire punctures into the myocardium, the guidewire is anchored using barbs, balloons or other actuatable members to secure the guidewire to the myocardium. Subsequently, using a push-pull mechanism, stents and other medical devices can be advanced over the guidewire into the myocardium.
