Abstract
A bendable sheath and a delivery system using the bendable sheath. The bendable sheath comprises a tube body (). The tube body () comprises a distal end and a proximal end. A tube wall of the tube body () is connected to a pull wire (). One end of the pull wire () extends towards the proximal end of the tube body (), and the other end is connected to the tube body () near the distal end of the tube body (). The pull wire () comprises at least a section thereof disposed freely outside the tube body () and near the distal end of the tube body (). The pull wire () in the bendable sheath comprises the section disposed freely outside the sheath tube body () and, when pulled, the section is disposed so as to facilitate the application of force. The section moves relative to the tube body (), such that a force application point is adaptively changed. The present invention improves the safety and flexibility of operations when there is a large bending radius, or when using long, hard, or inflexible intervention apparatuses.
