  • Vascular implant retrieval assembly and method
    Patent number: 9398945
    Abstract: A retrieval assembly for retrieving an implanted device includes an outer catheter; an interior tube arrangement with a first tube extending through the catheter lumen and having a first distal end, and with a second tube having extending through the catheter lumen outside the first tube. The second tube has a distal portion extending distally past the first distal end with a bend toward the first tube axis and with a second distal end. An entangling element is configured to be advanced through the second tube past the second distal end and to be at least partially retracted into the second tube. A withdrawal tool configured for engaging the implanted device and for at least partially retracting the implanted device into the first tube. The entangling element may have a distal flexible coil, and the withdrawing tool may have a distal pickup hook.
