Problems solved by technology

These cutting sheath or laser sheath solutions can also cause problems because the tissue removed by the sheath tends to build up in front of the sheath, eventually blocking the path the sheath is supposed to clear
[0005] Another option is to leave the existing leads in place and insert new ones, but this is not the preferred solution because the unused leads create additional obstruction to blood flow and heart valve function, and can become infected

Abstract

A method for extracting a lead from a patient comprising: providing a lead removal stylet; inserting the stylet into the lead; locking the stylet to a position inside the lead; and vibrating the stylet with tissue disrupting vibration to cause the lead to vibrate and to disconnect from binding tissue.

Description

technical field [0001] The present disclosure has a system and method for removing implanted leads from a patient, and in particular, has such a system and method that significantly improves the removal process of such cardiac leads. Background technique [0002] Pacemaker or ICD (implantable cardioverter defibrillator) leads are fed into the heart through a large vein and connect the pacemaker to the implantation site of the electrodes that wire terminated. Sometimes, these inserted leads need to be removed for one or more reasons, including infection, malfunction, lead deterioration, pacing system upgrades, or venous occlusion / stenosis. [0003] Ideally (if the lead has been implanted for a short time), it should be possible to remove the lead by simple pulling, however, this is often not the case. Lead removal is often complicated by the attachment of the leads to the patient's body at different locations in the path from the cardiac rhythm device to the myocardium, as ...
