    • A design and a fabrication method for an intravascular imaging and therapeutic catheters for combined ultrasound, photoacoustic, and elasticity imaging and for optical and/or acoustic therapy of hollow organs and diseased blood vessels and tissues are disclosed in the present invention. The invention comprises both a device - optical fiber-based intravascular catheter designs for combined IVUS/IVPA, and elasticity imaging and for acoustic and/or optical therapy - and a method of combined ultrasound, photoacoustic, and elasticity imaging and optical and/or acoustic therapy. The designs of the catheters are based on single-element catheter-based ultrasound transducers or on ultrasound array-based units coupled with optical fiber, fiber bundles or a combination thereof with specially designed light delivery systems. One approach uses the side fire fiber, similar to the one utilized for biomedical optical spectroscopy. The second catheter design uses the micro-optics in the manner of a probe for optical coherent tomography.
    • 在本发明中公开了用于组合超声,光声和弹性成像以及中空器官和患病血管和组织的光学和/或声学治疗的血管内成像和治疗导管的设计和制造方法。 本发明包括用于组合的IVUS / IVPA的装置 - 基于光纤的血管内导管设计和弹性成像以及用于声学和/或光学治疗的组合 - 以及组合的超声,光声和弹性成像以及光学和/或声学的方法 治疗。 导管的设计基于基于单元件导管的超声换能器或基于超声阵列的单元,其与光纤,纤维束或其与特别设计的光输送系统的组合耦合。 一种方法使用侧火纤维,类似于用于生物医学光谱的那种。 第二导管设计以用于光学相干层析成像的探针的方式使用微光学。
