    摘要: A capsule is coupled to a tether that is manipulated to position the capsule and a scanner included within the capsule at a desired location within a lumen in a patient's body. Images produced by the scanner can be used to detect Barrett's Esophagus (BE) and early (asymptomatic) esophageal cancer after the capsule is swallowed and positioned with the tether to enable the scanner in the capsule to scan a region of the esophagus above the stomach to detect a characteristic dark pink color indicative of BE. The scanner moves in a desired pattern to illuminate a portion of the inner surface. Light from the inner surface is then received by detectors in the capsule, or conveyed externally through a waveguide to external detectors. Electrical signals are applied to energize an actuator that moves the scanner. The capsule can also be used for diagnostic and/or therapeutic purposes in other lumens.

    摘要: A catheter having an imaging device on its distal end serves as a guidewire for cannula tools, enabling the tools to be advanced to a desired site in a patient's body. One exemplary embodiment of such a catheter is a scanning fiber endoscope. The images facilitate navigation through linked body lumens and also enable an operator to view a site where a biopsy sample is to be taken with a cannula tool. Exemplary cannula tools include bristles or sharp points that scrub cells from adjacent tissue, a biopsy needle that can be thrust into tissue, a loop that cuts away tissue, a cutting edge that slices tissue from a site, and forceps. The sample can be carried by a bodily or introduced fluid to a proximal end of the catheter through an annular gap between the catheter and the cannula tool, or the cannula tool can retain the sample.

    摘要: A method of one aspect may include monitoring movement of a scanning beam image acquisition device. Images may be acquired with the scanning beam image acquisition device using a first image acquisition mode when the monitoring indicates that the scanning beam image acquisition device is moving. Images may be acquired with the scanning beam image acquisition device using a second image acquisition mode when the monitoring indicates that the scanning beam image acquisition device is substantially still. The second image acquisition mode is different than the first image acquisition mode. In one aspect, the first mode has a relatively higher frame rate and relatively lower number of lines of image resolution than the second mode.

    摘要: An optical fiber conveys light from a source at a proximal end, to a distal end, where a piezoelectric material tube applies a force that causes the distal end of the optical fiber to scan in a desired pattern. Light from the distal end of the optical fiber passes through a lens system and is at least partially reflected by a reflective surface toward a side of the scope, to illuminate tissue within a patient's body. Light received from the internal tissue is reflected back either to collection optical fibers, which convey the light to proximally disposed optical detectors, or directly toward distal optical detectors. The optical detectors produce electrical signals indicative of an intensity of the light that can be used for producing an image of the internal tissue. The light received from the tissue can be either scattered, polarized, fluorescent, or filtered, depending on the illumination light.
