ABSTRACT:
An endoscope includes a handle assembly and an elongate probe defining a channel which extends to a distal end of the endoscope. A fiber is disposed in the channel and has a failure mode characterized by a first bending radius. The channel is potted with a compound which distributes bending stresses along the fiber providing the fiber with a failure mode characterized by a second bending radius shorter than the first bending radius. An associated method includes the step of potting the channel with an epoxy having, in a cured state, a durometer of about Shore 70A.
