Torque devices for use with intravascular devices and associated systems and methods

An intravascular system, comprising:

• an intravascular device comprising:
• a flexible elongate member having a proximal portion and a distal portion;
• at least one sensing element secured to the distal portion of the flexible elongate member;
• and
• at least one communication line extending from the at least one sensing element to the proximal portion of the flexible elongate member;
• and
• a torque device configured to selectively interface with the proximal portion of the flexible elongate member, the torque device including:
• a first component having a body defining a tapered opening for receiving a proximal end of the flexible elongate member, a first arm extending from the body, and a second arm extending from the body;
• and
• a second component movably coupled to the first component, wherein the second component is movable relative to the first component between an open position where the torque device is configured to slidably receive the proximal portion of the flexible elongate member between the first and second arms of the first component and a closed position where the torque device fixedly engages the proximal portion of the flexible elongate member between first and second arms of the first component.
