    摘要： A helical surgical snare (10) for engaging and capturing a foreign body for example in the vascular system of a human or animal body. The helical surgical snare includes an elongated tubular member (11) with the distal portion (34) of a filament wire (17) wrapped around the exterior surface (15) of the distal portion of the tube. The filament wire is positioned within the passage (14) of the tubular member and exits about the distal portion (25) thereof via inclined side ports. The distal end (18) of the filament wire is attached in the passage to the distal end (13) of the tubular member. A helical snare loop (19) is formed externally around the tubular member between the two side ports (16, 20). A handle (30) positioned at the proximal end of the tubular member pushes and pulls the distal portion of the filament wire to operate the snare loop between various open and collapsed positions.

    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： A medical device for localizing a nonpalpable breast lesion. The device includes a tubular introducer needle and a wire guide positioned therein for inserting into a breast to the site of the lesion. The wire guide includes a distal portion having a preformed, resilient helical coil configuration for locking into position about the lesion. The distal portion includes a superelastic metallic alloy for maintaining the helical coil configuration after repeated extensions from and retractions into the needle passageway. The needle is inserted with the wire guide positioned therein into the breast to the site of the lesion and from the distal portion of the needle. The distal end of the needle includes a plurality of indentations for enhancing the ultrasound visualization thereof. As the distal portion of the wire guide emerges from the needle, the acuate distal end of the wire guide cuts into and scribes a helical path about the tissue distal to the lesion. The remainder of the distal portion of the wire guide follows the path scribed by the acuate distal tip and locks about the tissue distal to the lesion. Should the needle and wire guide not be appropriately positioned, the distal portion of the wire guide is retracted into the passageway of the needle to reposition the needle and guide. After desired positioning, the needle is removed with the wire guide remaining in a locked position distally about the lesion for guiding the surgeon to the lesion site during subsequent surgery.

    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.

    摘要： A percutaneous release mechanism (57) for use with an intravascular treatment device (11) in an intravascular treatment system (10). The release mechanism includes an inner member (17) having a connection mechanism (18) positioned about the distal end (14) thereof for interconnection with another connection mechanism (12) positioned on an intravascular treatment device. The release mechanism also includes an outer member tube (13) of which the inner member is positioned therein. The first and second connection mechanisms are interconnectable and positionable in the passage (16) of the tube for delivering the treatment device in a delivery state to the treatment site. The release mechanism also includes a handle (37) having parts (38, 39) connected to the inner member and outer tube, whereby movement of the proximal end of the inner member is translated to the distal end thereof for extending the interconnected connection mechanisms from the passage of the outer member tube and positioning the treatment device in a treatment state. The intravascular treatment system includes the percutaneous release mechanism along with the intravascular treatment device. The treatment device includes an occlusion coil (23) and a rigid tube (36) connected to the flexible outer member tube (35) for maintaining the delivery coil in a delivery state. In another example, the treatment device includes a blood clot filter (40) in which the percutaneous delivery mechanism is adapted for connection thereto.

    摘要： A joint and a laminate including a nickel-titanium alloy such as nitinol and a method for preparing the surface of a nickel-titanium alloy member for bonding solder material and, electively, another similar or dissimilar member thereto. The method includes applying an aluminum paste flux to the titanium oxide coated surface of a nickel-titanium alloy member and heating the flux to its activation temperature. The flux removes and suspends the titanium oxide therein along with leaching titanium from the base alloy member surface to form a nickel-rich interface surface. The activated flux also coats the nickel-rich interface layer for protection from further oxidation. A bonding material such as a tin-silver solder is flowed onto the nickel-rich interface surface to displace the activated flux. Electively, another member is applied to the molten solder to form a joint between the two members. The residual flux is cleaned from the joint to prevent further deterioration of the base metal. The solder joint includes the base nickel-titanium alloy metal, the nickel-rich interface surface, and the solder material. Electively, any other member may be applied to this joint in the molten state to form a metallic bond therebetween.
