EXTRACTABLE IMPLANTABLE MEDICAL LEAD

摘要

A medical electrical lead provided with a generally isodiametric lead body. The lead body includes a first elongated plastic tube and an elongated conductor mounted in the first plastic tube. A first coil electrode is mounted exterior to and around the outer surface of the first tube and is coupled to the conductor. A second elongated plastic tube having an outer diameter approximately equal to the outer diameter of the first coil electrode, is mounted exterior to and around the outer surface of the first tube adjacent the first coil electrode and extends proximally therefrom. A second coil electrode having an outer diameter approximately equal to the outer diameter of the first coil electrode may be mounted exterior to and around the first tube proximal to the first coil electrode such that the second elongated plastic tube extends to a point adjacent the second coil electrode. A third elongated plastic tube having an outer diameter approximately equal to the outer diameter of the second coil electrode may be mounted exterior to the first tube adjacent the second coil electrode and extending proximally therefrom. In a preferred embodiment, the first tube is an extruded multi-lumen tube.
