| 摘要 |
An intraluminal system for retrieving an implantable medical device from a body vessel includes, according to one embodiment, a grasping component including at least one deployable arm, where a proximal end of the arm is configured to extend away from a longitudinal axis of the system when deployed, and a first sheath disposed adjacent to the grasping component, where the first sheath includes a radially expandable portion at a distal end thereof. A second sheath overlies the first sheath and the grasping component. Relative motion between the second sheath and the grasping component allows the proximal end of the deployable arm to be deployed for grasping a distal portion of an implantable medical device, and relative motion between the second sheath and the first sheath allows the expandable portion of the first sheath to radially expand to receive a proximal portion of the implantable medical device.
