摘要： The laser induced liquid jet generating apparatus irradiates a laser beam on a liquid in a main body, guides the generated liquid jet into a catheter via a nozzle, and generates a flow in the direction opposite the liquid jet. Even by the use of a catheter having a small outside diameter, therefore, the apparatus is enabled to effect powerful laser irradiation without being thermally affected by the laser beam and consequently shatter thrombus, for example, and recover by aspiration the shattered thrombus through the distal end of the catheter.

摘要： A wire to remove an intravascular foreign body includes a flexible long wire body, a foreign body capturing portion to capture a foreign body in a vessel, and an operating wire to deform the foreign body capturing portion. The foreign body capturing portion includes a first capturing part and a second capturing part. The first capturing part is formed from a filament which assumes a helical shape in its natural state and is arranged on the forward end of the wire body. The second capturing part is formed from a filament which assumes a helical shape in its natural state and is arranged on the forward end of the first capturing part. The first and second capturing parts together form a rearwardly open space for capturing the foreign body when the wire is moved rearwardly relative to the foreign body. The second capturing part is deformable such that the distance between its adjacent filaments decreases upon operation of the operating wire. The wire is capable of surely capturing and removing a foreign body in the vessel.

摘要： An ultrasonic imaging catheter includes an outer sheath that is adapted to be inserted into a body cavity, and a drive shaft that is positioned in the outer sheath for transmitting mechanical driving force. The catheter is also provided with first and second elastic members. The first elastic member is disposed at the tip portion of the outer sheath while the second elastic member that is secured to the housing containing a transducer has a free end that is inserted into the first elastic member. The portion of the catheter between the housing and the first elastic member at the free end of the catheter is thus reinforced to improve flexibility and kinking of the catheter. The housing can be made of insulating ceramic material so that the insulation and resistance of the housing is high. Thus, a short between the electrodes of the oscillator does not occur even when the oscillator is in direct contact with the housing.
摘要翻译：超声波成像导管包括适于插入体腔的外护套，以及定位在外护套中用于传递机械驱动力的驱动轴。导管还设置有第一和第二弹性构件。第一弹性构件设置在外护套的顶端部分，而固定到容纳换能器的壳体的第二弹性构件具有插入到第一弹性构件中的自由端。因此，在导管自由端处的壳体和第一弹性构件之间的导管部分被加强以提高导管的柔性和扭结。外壳可以由绝缘陶瓷材料制成，使得外壳的绝缘和电阻很高。因此，即使当振荡器与壳体直接接触时，也不会发生振荡器的电极之间的短路。

摘要： A guide wire comprising a super-elastic core member which consists of a proximal section, a distal section smaller in diameter than the proximal section and a intermediate section between the proximal section and the distal section, an X-ray opaque metal coil attached to the distal section of the core member in tight contact with the distal section, a synthetic resin envelope which covers the core member and the X-ray opaque metal coil to form a substantially smooth outside surface, and a hydrophilic lubricative layer which covers the outside surface of the synthetic resin envelope. The distal section of this guide wire can be reshaped repeatedly. The X-ray visibility of the distal section is improved.
