Apparatus for acquiring in vivo images of a site of interest within the internal organs of a body. The apparatus includes an elongate, flexible catheter. The catheter is introducible into the body and has a first end that remains external to the body and a second and positionable adjacent the site of interest. A movable scanning unit having at least one sensor for acquiring images is housed adjacent the second end of the catheter. There is a drive mechanism to control movement of the movable scanning unit from the first external end of the catheter to acquire multiple images of the site of interest. The drive mechanism has a control element extending the length of the catheter lumen adapted for linear movement within the lumen to generate linear or rotational movement of the scanning unit.

Apparatus for in vivo imaging of the respiratory tract and other internal organs

Methods and apparatus for detecting the possible rejection of a transplanted tissue by a host. The transplanted tissue is subjected to illumination with light to induce fluorescence. The light can be ultraviolet light, visible light or infrared light, which can be used alone or in any combination, which means one, two or three forms of light may be used together. The induced fluorescence is collected and analyzed, then compared with fluorescence that is obtained using the same procedure for a known, healthy tissue that is the same type of tissue as the transplanted tissue. Also provided are methods and apparatus related to the determination of probe orientation and the need for biopsy.

Apparatus and methods that permit the direct viewing of induced tissue fluorescence or other response by a human viewer through an endoscope without the need for bulky and expensive auxiliary apparatus such as imaging devices, sensor arrays, analyzing systems and computer hardware and software. The apparatus and methods provide an excitation energy, such as blue light, that is transmitted to the target, and then the endoscope collects the emitted response, which is typically fluorescent light of a wavelength longer than the UV or blue light used to induce the fluorescence. The endoscope then transmits the response through a series of filters in the endoscope and directly to the eye of a human user.
