  • Publication number: 20110106099
    Abstract: The disclosure pertains to a lead extraction device which utilizes a chamfered coring tip to separate an implanted object, such as a pacemaker lead, from fibrous tissue and thereby permit the implanted object to be extracted from a body. The lead extraction device features an elongate body having a lead gripping mechanism. The gripping mechanism grips a lead to prevent kinking or simultaneous rotation of the lead with the lead extraction device that may cause tissue damage. The inner lumen of lead extraction device is preferably dimensioned so that a lead will fit within. The lead extraction device is thereby tracked over the lead. The chamfered coring tip on the distal end of the lead separates the lead from fibrous tissue. Through the disclosed lead extraction devices of the present disclosure, the lead may be separated along its length, as well as separated at its distal end from fibrous tissue, thereby permitting the lead to be readily extracted from the body.
