Abstract: Systems, methods and apparatus for acquiring an image from within a body lumen are provided. Systems embodying features of the invention include an intracorporeal imaging component for acquiring imaging information, an image information recording component, and an image information playback component. Methods for acquiring image information from within a body lumen include steps of acquiring imaging information, storing image information, and playing back imaging information. Imaging information may be played back as acquired, or non-sequentially, or composite images may be formed by combining, filtering, enhancing, or subtracting images and the composite images displayed. Devices embodying features of the invention include optical imaging components such as an optical IGW, an optical imaging recording component, and an optical image playback component. The systems, methods and devices are suitable for use with angiopoplasty, stent delivery, and other intracorporeal clinical procedures.

Abstract: The invention is directed to apparatus, methods and systems including a sheath for use with intracorporeal optical imaging instruments such as imaging guidewires, catheters, or endoscopes. The invention provides a sheath suitable for guiding an enclosed instrument, that is effective to guide the placement within a patient's body and replacement to a distal position after retraction of the imaging instrument, as during an imaging scan. The sheaths may include at least a portion that is translucent to a desired wavelength of radiation. The translucent portion may have an index of refraction similar to the index of refraction of a bodily fluid such as blood plasma, or an artificial fluid suitable for introduction into a body lumen.
