Endovascular Optical Coherence Tomography Device

摘要

An endovascular OCT probe is included in an endovascular access device for intravascular imaging. The probe includes a hollow coil wire defining an axial lumen of the endovascular access device. A single mode optical fiber for transmitting light is disposed in the axial lumen of the hollow coil wire so that translation and rotation of the hollow coil wire carrying the optical fiber within the endovascular access device is stabilized for scanning endovascular tissue with at least 5 microns resolution. An optic element directs light from and into the optical fiber at a distal tip of the optical fiber and is coupled to or fixed to the distal end of the optical fiber. The optic element and the distal end of the optical fiber is disposed within a glass ferule to protect it from damage.
