    摘要: A system includes an expandable distal-end assembly, a proximal position sensor, a distal position sensor, and a processor. The expandable distal-end assembly is coupled to a distal end of a shaft for insertion into a cavity of an organ of a patient. The proximal and distal position sensors are located at a proximal end and a distal end of the distal-end assembly, respectively. The processor is configured to estimate a position and a longitudinal direction of the proximal sensor, and a position of the distal sensor, all in a coordinate system used by the processor. The processor is further configured to project the estimated position of the distal sensor on an axis defined by the estimated longitudinal direction, and calculate an elongation of the distal-end assembly by calculating a distance between the estimated position of the proximal sensor and the projected position of the distal sensor.

    摘要: A system and method for achieving linear alignment between elements in a procedure are disclosed. The system and method include determining the axis of a first element, such as the ostium, of a plurality of elements utilized in the procedure, determining the axis of a second element, such as a catheter, of the plurality of elements utilized in the procedure, and aligning the determined axis of the first element and the determined axis of the second element. The method may include further determining the axis of a third element, such as a sheath of the catheter, of the plurality of elements utilized in the procedure and aligning the determined axis of the third element with the aligned axis of the first element and the aligned axis of the second element.

    摘要: An electronic device includes a housing, which is sized and shaped to fit snugly over a connector containing first electrical contacts at an end of a cable. The electronic device further includes second electrical contacts within the housing and test circuitry. The second electrical contacts are configured and positioned to mate with the first electrical contacts when the housing is fitted over the connector. The test circuitry is contained within the housing and coupled to the second electrical contacts and configured to test a functionality of the cable.
