摘要：
A medical device, system, and method having a flexible shaft and a multi-core fiber within the flexible shaft. The multi-core fiber includes a plurality of optical cores dedicated for shape sensing sensors, and a plurality of optical cores dedicated for force sensing sensors. A medical device flexing structure assembly can comprise a multi-core fiber comprising a plurality of cores, and a flexing structure comprising at least one slot. Each of the plurality of cores can comprise a fiber Bragg grating, and the flexing structure can be configured to bend in response to a force imparted on the flexing structure.
