  • Distal end supported tissue slitting apparatus
    Patent number: 10835279
    Abstract: Methods and systems for separating an object, such as a lead, from formed tissue are provided. Specifically, a tissue slitting apparatus is configured to engage formed tissue at a slitting engagement point. While the object is subjected to a first traction force, the tissue slitting apparatus is caused to move further into the engaged tissue and slit the tissue past the point of engagement. The slitting apparatus causes the tissue to separate along an axial direction of the length of the formed tissue and releases at least some of the force containing the object. The slitting apparatus is supported by a distal end support device configured to lock onto the lead. While supported, a slitting element of the apparatus places fibers of the formed tissue under tension and performs a lifting cut operation. The methods and systems are well suited for use in cardiac pacing or defibrillator lead explant procedures.
