ABSTRACT:
An improved lead extraction system having multiple-jaw cutting edge that is useful for extraction and removal of unwanted lead by a minimal invasive procedure. A lead extraction system suitable for radiofrequency ablation of scar tissues surrounding the implanted lead comprises a catheter sheath having a distal end, a proximal end and at least one lumen extending therebetween, wherein a locking stylet is provided. In one embodiment, the lead extraction system has fluid infusion and irrigation means at its distal tip section and a set of ablation electrodes for loosening the target tissue by applying radiofrequency energy and cooled fluid to said electrode and its contacted tissue.
