Abstract

Systems and methods are provided for extracting an implanted lead from a patient's body. The system may include a dilator and a trephine for extracting the electrode lead. A sheath may be included that is advanced over the proximal end of an electrode lead until the distal end of the sheath abuts a collar of the electrode lead coupled to proximal fixation elements. The dilator may be rotatably and axially advanced over the sheath until the distal end of the dilator collapses the proximal fixation elements within a lumen of the dilator. The trephine may then be rotatably and axially advanced over the dilator such that a cutting edge of the trephine cuts tissue surrounding distal fixation elements of the electrode lead to thereby dislodge the electrode lead.
