Abstract
Systems and methods for delivering an implantable occluder device, e.g., an atrial septal defect occluder having a bioresorbable frame, to the atrial septum of a patient are provided. The system may include an outer shaft configured to be removably coupled to a proximal end of the occluder, an inner shaft slidably disposed within the outer shaft and configured to be removably coupled to a distal end of the occluder, and an outer sheath slidably disposed over the outer shaft and having an expandable distal region configured to transition between a collapsed delivery configuration defining an atraumatic tip, and an expanded configuration to facilitate passage of the occluder therethrough. The system may include a handle having slidable and rotatable actuators operatively coupled to the outer shaft, inner shaft, and outer sheath for deploying and releasing the occluder at the atrial septum.
