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： 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 scanning flexible endoscope includes a tether attached to a capsule. The tether controls a disposition of the capsule within a body lumen such as the esophagus. A scanning device in the capsule optically scans the adjacent tissue on the inside surface of the body lumen as the capsule is moved axially through the body lumen. A non-contact sensor responds to indicia on the tether to measure a relative position of the tether and the capsule in the body lumen. The indicia can be analog or digital in form and the sensor can be either magnetic, or optical. A wiper is optionally provided to remove bodily fluids from the tether when pulled from the body lumen past the sensor. A pulse of fluid can be delivered to the distal end of the tether to cause the body lumen to distend, facilitating free movement of the capsule in the lumen.
