摘要： A guidewire includes a tapered core, an elongated non-radiopaque inner coil that is coincident with the core and extends over a distal portion of the core, and a radiopaque outer coil that fits over a distal end of the inner coil. The inner coil tapers between its proximal end and distal end, to form a tapered distal end section. The outer diameter of the proximal end of the inner coil is the same as the outer diameter of the proximal end of the core, before its first taper, and similarly, the outer diameter of the outer coil is the same as the outer diameter of the inner coil before its taper. Accordingly, the guidewire has an essentially uniform outer diameter over its entire length. A rounded tip that acts as a deformable buffer is formed where the distal ends of the two coils and the core join. The distal end of the core is preferably flattened to provide a formable end to the guidewire. A low friction coating may be added to the wire, to facilitate movement of the wire through the arteries.

摘要： A device and method for treating tissue at a treatment site. The device and method include supplying controlled energy to a heating portion of the device positioned within a tissue wall at the treatment site. The size of the heating portion and energy supplied provides for ablation of the tissue to form a cavity within the tissue wall without ablating the surfaces of the tissue wall. Treatment fluid can then be supplied through the device to the cavity to supplement growth of blood vessels or retard such growth at the treatment site. The device can also be used to create an injury zone at a treatment site without ablating tissue, wherein the injury zone can be injected with treatment fluid. The device and method has use anywhere within the body, especially in the regions of the heart.

摘要： This invention provides a small diameter snare device consisting of a hollow, elongate, thin-walled polymer outer sheath. A single central core wire extends through the entire length of the sheath. The outer diameter of the core wire is sized close to the inner diameter of the sheath while allowing for axial sliding, in order to maximize the support to the body portion of the snare device. The distal end of the core wire has a tapered section of reduced diameter or cross section to provide a "guidewire-like" flexibility to the distal portion of the device. A second wire of about fifty percent of the inner diameter of the sheath is shaped to form a snare loop and the two ends are attached to the distal most portion of the central core wire via welding, soldering, or brazing. After assembly of the core and sheath, a second short, hollow tube is fitted over the proximal end of the central core and attached thereto to provide an actuating handle to slideably move the central core within the sheath, thus exposing and retracting the snare loop from the open distal end of the sheath. The loop is typically circular or oval shaped and can also be multiplanar (for example, a twisted, figure eight shape) so as to increase the ability to ensnare and capture objects. The loop attachment to the core wire is facilitated and strengthened by a wrapped coupling coil formed typically of 0.001-inch platinum wire applied to secure the loop prior to soldering (brazing or other metal-flowing joining techniques), and through which solder flows to permanently secure the loop to the core wire.

摘要： A guidewire includes (i) a tapered core; (ii) an elongated non-radiopaque coil that is coincident with the core and extends over a distal portion of the core up to a proximal portion of a tapered end section of the core; and (iii) a radiopaque plastic tip that fits over the distal end of the core. The proximal end of the plastic tip may extend over the distal end of the non-radiopaque coil. The tip may then be attached to the coil by forcing the proximal end of the tip through the windings at the distal end of the coil. The distal end of the plastic tip extends slightly beyond the distal end of the core, to form a deformable bumper. The outer diameter of the proximal end of the plastic tip is the same as the outer diameter of the coil, which is the same diameter as proximal end of the core before its first taper. Accordingly, the guidewire has an essentially uniform outer diameter over its entire length. The durometer hardness of the plastic material used to form the tip may be adjusted, to alter the stiffness of the tip. Thus, the tip may be made stiffer or more flexible without changing the outer dimensions of the guidewire. The tip may also be tapered, as desired, to narrow the outer diameter of the distal end of the guidewire. A low friction coating may be added to the wire, to facilitate movement of the wire through the arteries.
摘要翻译：导线包括（i）锥形芯; （ii）细长的非辐射不透线圈，其与所述芯重合并且在所述芯的远端部分上延伸到所述芯的锥形端部的近端部分; 和（iii）不透射线的塑料尖端，其装配在芯的远端上方。塑料尖端的近端可以在非不透射线圈的远端上延伸。然后可以通过迫使尖端的近端通过线圈的远端处的绕组来将尖端附接到线圈。塑料尖端的远端稍微延伸超过芯的远端，以形成可变形的保险杠。塑料尖端的近端的外径与线圈的外径相同，线圈的外径在其第一锥度之前具有与芯的近端相同的直径。因此，导丝在其整个长度上具有基本均匀的外径。可以调整用于形成尖端的塑料材料的硬度计硬度，以改变尖端的刚度。因此，尖端可以变得更硬或更灵活，而不改变导丝的外部尺寸。根据需要，尖端也可以是锥形的，以缩小导丝的远端的外径。可以将低摩擦涂层添加到线中，以便于电线穿过动脉的移动。
