摘要： An intraluminal imaging catheter comprises an outer sheath of material that is efficiently transmissive of near infrared light, a guidewire lumen section extending distally from a distal end of the outer sheath, a terminal length section of the outer sheath extending proximally from the guidewire lumen section, a cable longitudinally and rotatably disposed lengthwise within the outer sheath and having an imaging tip located at its distal end including optical components for transmitting and receiving near infrared light, wherein the cable is longitudinally extendable to position the imaging tip at the terminal length section of the outer sheath, and reinforcement means for structurally reinforcing the terminal length section of the outer sheath against transverse bending or kinking.

摘要： A method of imaging a vessel with a catheter includes positioning an imaging tip in a reinforced terminal section of an outer sheath of the catheter, inserting the catheter into a vessel, and performing near infrared spectroscopy of the vessel by retracting the imaging tip to a retracted position proximally spaced from the reinforced terminal section of the outer sheath, transmitting near infrared light from the imaging tip to the vessel wall via the outer sheath, and collecting near infrared light from the vessel wall at the imaging tip via the outer sheath. Transmitting and collecting may be performed after retracting the cable and while the imaging tip is rotated and translated proximally from the retracted position along the outer sheath. Ultrasound energy may be transmitted to the vessel from a transducer on the imaging tip and received from the vessel at the transducer.
