Abstract
A thrombectomy device includes a handle at a proximal end portion of the device, a cage at a distal end portion of the device, the cage being moveable between an expanded orientation and a contracted orientation, and a first tube extending from the proximal end portion of the device to at least a proximal end portion of the cage. The device also includes a second tube extending from the proximal end portion of the device to at least a distal end portion of the cage, and a self-adjusting control assembly including a biasing element coupled to one of the first tube or the second tube. The biasing element exerts an axial force to urge the cage toward the expanded orientation.
