Abstract: An endoscope with flexible cable is described having a first set of means to facilitate travel of an imaging capsule down the esophagus, a second set of means to enable proper orientation and optical clarity of the capsule, and a third set of means to enable ease in retrieval of the device. In most embodiments, there is an overlap of these sets of means, the combination of which assures optimal exam effectiveness while maintaining a high degree of patient comfort. The endoscope can target low cost, high volume screening for diseases of the upper digestive tract.

Abstract: A device (10) used with high frequency ultrasound provides a replaceable barrier between the ultrasound transducer and the tissues being imaged. The device (10) provides an acoustic pathway of minimal effect on the ultrasound signals, and furthermore provides for a safety barrier between a mechanical scanner and the tissues being imaged. The configuration of the device (10) allows it to function as a standoff for the ultrasound transducer to place the focus of the ultrasound beam at the desired depth of tissue for imaging. In addition, the device (10) may be sterilized and replaced as needed, providing sterile tissue contact surfaces. The device (10) has additional features, which are especially advantageous for diagnosis and surgery of the eye.
