Abstract:
A flexible endoscope providing increased control to an operator or user, the flexible endoscope utilizing an ionic polymeric material positioned in the shaft of the endoscope, such that, upon application of an electrical current to the ionic polymeric material, the material contracts and becomes relatively rigid. The flexible endoscope may further include mechanical controls for control of the flexible shaft allowing the user to simultaneously actuate both the polymeric material and mechanically deflect the shaft.
