Abstract
An actively bendable sheath such as ureteral access sheath (UAS) and a method for delivering a medical instrument (e.g. a ureteroscope) therethrough are disclosed. The sheath's tubular wall includes a deflectable or bendable segment at or adjacent to the distal sheath end. Two pull/control wires are slidably disposed within two separate dedicated channels/lumens and attached to points distally beyond the deflectable segment. The bendable segment may be passively bended by force from a bending medical instrument within it or by the force of a surgeon pulling one of the two pull/control wires.
