1. A body cavity drainage device for a patient, comprising:
a drainage tube having a proximal end, a distal end, and one or more lumens extending longitudinally through a wall thereof, the distal end configured to be inserted into a body cavity of a patient to facilitate use of the body cavity drainage device; and an activation apparatus configured to alter a position of the distal end of the drainage tube relative to the proximal end of the drainage tube, the activation apparatus comprising:
a rotatable control device;one or more elongated flexible members disposed within the one or more lumens extending longitudinally through a wall of the drainage tube, the one or more flexible members operably coupled to the rotatable control device at a proximal end of the one or more flexible members and to the drainage tube at or near a distal end of the one or more flexible members; anda compliant locking mechanism configured to maintain an angular position of the rotatable control device when in a locked position and in the absence of a torque applied to the rotatable control device, and to allow rotation of the control device when in an unlocked position upon application of a torque to the rotatable control device. |
