  • Tissue separating systems and methods
    Patent number: 10869687
    Abstract: Systems and methods for separating an object such as a pacing lead from a patient tissue involve a flexible and torqueable shaft having an internal lumen sized to receive the object, and a hard separating mechanism for separating the object from the tissue. Typically the shaft and separating mechanism are advanced along or toward the object, and the separating mechanism is contacted with the tissue. The shaft is rotated to effect separation between the object and the tissue. The systems and methods are well suited for use in cardiac pacing or defibrillator lead explant procedures.
    Type: Grant
    Filed: September 20, 2017
    Date of Patent: December 22, 2020
    Assignee: SPECTRANETICS LLC
