  • Suture tracking dilators and related methods
    Patent number: 9623220
    Abstract: Suture tracking dilators and methods for removing implanted medical devices such as microstimulators or microsensors from living tissue are described. A suture tracking dilator has a slit running along its axial length. The slit can have a curved portion. A suture is attached to a medical device prior to its implantation. To remove the implanted medical device, the free end of the suture is exposed and inserted in the slit in the suture tracking dilator. The suture is held under tension at its free end, the dilator is inserted in the living tissue and the dilator follows the suture to the implanted medical device. The medical device is removed by pulling on the free end of the suture.
