    • PROBLEM TO BE SOLVED: To provide an intravascular probe improved in capability of detecting a lesion such as vulnerable plaque. SOLUTION: The intravascular probe includes a sheath with a distal portion and a proximal portion. The intravascular probe includes a first optical waveguide extending along the sheath, the first optical waveguide being configured to carry optical radiation between the distal and proximal portions, and a first beam redirector disposed at the distal portion in optical communication with the first optical waveguide. The intravascular probe also includes an optical detector configured to receive optical radiation from the first optical waveguide, and an ultrasound transducer disposed at the distal portion. The ultrasound transducer is configured to couple ultrasound energy between the intravascular probe and a transmission medium. A wire extends along the sheath in electrical communication with the ultrasound transducer. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:提供改善检测易损斑块等病变能力的血管内探针。 解决方案:血管内探针包括具有远侧部分和近端部分的护套。 血管内探针包括沿护套延伸的第一光波导,第一光波导被配置为在远端和近端部分之间承载光辐射,以及布置在远端部分处的与第一光波导光学通信的第一光束重定向器。 血管内探针还包括被配置为接收来自第一光波导的光辐射的光学检测器和设置在远端部分处的超声波换能器。 超声换能器配置成在血管内探针和传播介质之间耦合超声波能量。 电线沿着护套延伸,与超声换能器电连通。 版权所有(C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To improve the capability of a probe to detect a lesion such as vulnerable plaque by combining two detection modes of infrared spectroscopy and intravascular ultrasonic diagnosis within an identical probe, relating to a device for diagnosis of a lumen.SOLUTION: An intravascular probe 100 includes a sheath with a distal portion and a proximal portion. The intravascular probe includes a first optical waveguide extending along the sheath, the first optical waveguide being configured to carry optical radiation between the distal and proximal portions, and a first beam redirection changer disposed at the distal portion in optical communication with the first optical waveguide. The intravascular probe also includes an optical detector configured to receive optical radiation from the first optical waveguide, and an ultrasound transducer 120 disposed at the distal portion. The ultrasound transducer is configured to couple ultrasound energy between the intravascular probe and a propagation medium. A wire extends along the sheath in electrical communication with the ultrasound transducer.
