Removal of the lead. A special sheath (tube) is placed in the vein. This sheath is threaded over the lead and guided to the tip of the lead (where the lead attaches to the heart). A laser light or mechanical drill-like tip can often be attached to the sheath to help break up the scar tissue. The lead is then removed
Pacemaker or ICD Lead Extraction. In pacemakers and ICD, the leads are inserted into a lead under the collar bone and advanced into the heart. The body tries to heal any objects that are inserted into it and gradually the leads become coated with fibrous tissue. Over time the fibrous tissue may become attached to the heart and the blood vessels. The longer the period that the leads have been in place there is a
