IMPLANTABLE ELECTRIC LEAD

摘要

An implantable lead has a distal lead portion with at least one electrode electrically connected to a connector ring through a conductor running in a lumen of the lead. A proximal lead portion includes the connector ring, a connector pin and a connector coupling mechanically and coaxially connected to each other with the connector coupling as a bridging element. A rotational lock in the form of a circumferential element of an elastically deformable, flexible material is provided in the connector coupling in the interface between the coupling and the connector ring. This rotational lock prevents any rotation of the connector pin to be propagated into a rotation of the connector coupling and consequently reduces the risk of damages to internal lead components due to any such unintentional coupling rotation.
