摘要： A catheter for use in angioplasty includes a shaft formed from an elongated metallic tube and has an inflatable balloon at its distal end. A plastic tube connects a distal end of the metallic tube to a proximal end of the balloon. The metallic and plastic tubes thus define a lumen for providing inflation pressure to the balloon. A metallic core member is attached to the metallic tube and extends distally therefrom through the plastic tube and balloon. The distal end of the balloon is sealably secured to the core member. A tip body is connected to the core member distally of the balloon, with a short guide wire lumen being defined on the tip body. The guide wire lumen is adapted to slidably receive a guide wire which then extends along the catheter exteriorly of the balloon.

摘要： Devices and methods for sealing a passageway formed by a patent foramen ovale (PFO track) in the heart are provided. One method includes providing an abrading device to the PFO track and abrading the tissue within the PFO track. The abraded tissue forming the PFO track is then held together under pressure, either via lowering right atrial pressure or via applying suction to the septum primum to pull it into apposition against the septum secundum. After a sufficient period of time, the pressure is released and the abraded tissue heals to form a robust seal over the PFO track. Additionally, several devices are provided which can be placed into the PFO track to apply adhesive to the walls of the PFO track. The devices may or may not be left within the PFO track. If the devices are not left within the PFO track, the walls of the PFO track, covered with adhesive, are brought into apposition with one another and adhered together. If the device is left within the PFO track, the device is flattened from an expanded configuration to a flattened configuration, and the walls of the PFO track, adhering to the outer surface of the device, are pulled toward each other as the device flattens. The device may also include interior structure to hold the device in a flattened configuration.
摘要翻译： 提供用于密封由心脏中的卵圆孔卵孔（PFO轨迹）形成的通道的装置和方法。 一种方法包括向PFO轨道提供研磨装置并研磨PFO轨道内的组织。 形成PFO轨道的磨损组织然后在压力下保持在一起，或者通过降低右心房压力或通过向隔膜施加抽吸使其与隔膜隔层相对。 经过足够的时间后，释放压力，磨损的组织愈合，在PFO轨迹上形成牢固的密封。 另外，提供了可以放置到PFO轨道中以将粘合剂施加到PFO轨道的壁上的几个装置。 设备可能会留在PFO轨道中，也可能不会留在PFO轨道中。 如果设备不在PFO轨道内，PFO轨道的墙壁被粘合剂覆盖，彼此并置并粘合在一起。 如果设备留在PFO轨道内，则设备将从扩展配置平坦化到平坦的配置，并且随着设备平坦化，PFO轨道的粘附在设备外表面上的墙壁会相互拉紧。 该装置还可以包括用于将装置保持在扁平结构中的内部结构。

摘要： A steerable guide wire includes a core wire having a proximal end and a distal end. A braided filament is affixed to the distal end of the core wire. An outer coil surrounds at least a portion of the core wire and the braided filament. A proximal end of the braided filament is secured to a distal end of the coil. By locating the braided filament in the distal tip portion of the guide wire, a guide wire is provided that is highly flexible, has a high degree of tensile integrity, and is highly steerable, even in tortuous vasculature. Filter and balloon catheters having braided filaments at the distal end are also described.

摘要： An evacuation sheath assembly and method of treating occluded vessels which reduces the risk of distal embolization during vascular interventions is provided. The evacuation sheath assembly includes an elongated tube defining an evacuation lumen having proximal and distal ends. A proximal sealing surface is provided on a proximal portion of the tube and is configured to form a seal with a lumen of a guided catheter. A distal sealing surface is provided on a distal portion of the tube and is configured to form a seal with a blood vessel. Obturator assemblies and infusion catheter assemblies are provided to be used with the evacuation sheath assembly. A method of treatment of a blood vessel using the evacuation sheath assembly includes advancing the evacuation sheath assembly into the blood vessel through a guide catheter. Normal antegrade blood flow in the blood vessel proximate to the stenosis is stopped and the stenosis is treated. Retrograde blood flow is induced within the blood vessel to carry embolic material dislodged during treating into the evacuation sheath assembly. If necessary to increase retrograde flow, the coronary sinus may be at least partially occluded. Alternatively, antegrade flow may be permitted while flow is occluded at the treatment site.

摘要： A guide wire, and a method for the manufacture thereof, having a core and a plastic jacket enclosing the core. The plastic jacket comprises a proximal portion formed of a first plastic material and a distal jacket portion formed of a second plastic material. The distal end of the proximal jacket portion and the proximal end of the distal jacket portion substantially abut each other and are of substantially equal outer diameters so as to form a smooth transition between the proximal and the distal jacket portions. According to another aspect, there is provided a guide wire with a selectively formable metallic core and a plastic jacket encasing the formable core. The plastic jacket has a distal portion with a hydrophilic coating and a proximal portion without a hydrophilic coating. According to another aspect, there is provided a guide wire having a formable metallic core and a plastic jacket encasing the formable core. The plastic jacket has a distal portion that is more radiopaque than a proximal portion.
