Abstract
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.
