LOW PROFILE, VENTRICULAR, TRANSVENOUS, EPICARDIAL DEFIBRILLATION LEAD

摘要

A cardiac lead designed for implantation in the vasculature of the left side of the heart comprising a flexible lead body having a central lumen, a removable terminal pin, electrodes electrically coupled to the removable terminal pin, a mechanism for securing the electrodes in the proper position in the vasculature and a mechanism for sealing the central lumen after implantation to prevent body fluids from invading the lumen. The cardiac lead can be implanted or explanted using either a guidewire, a guide catheter or both.
