Implantable electric lead
First Claim
1. An implantable electric lead comprising:
- a lead body comprising a lumen;
a distal lead portion comprising an electrode;
a conductor electrically connected to said electrode and running in said lumen;
a proximal lead portion comprising;
a connector pin connectable to an implantable medical device;
a connector ring electrically connected to said conductor;
a connector coupling mechanically interconnecting said connector pin and said connector ring, said connector pin, said connector ring and said connector coupling being co-axially arranged relative each other in said proximal lead portion; and
a rotational lock formed by a circumferential or circumferentially distributed element of an elastically deformable, flexible material in said connector coupling in an interface between said connector coupling and said connector ring and arranged for restraining rotation of said connector coupling relative said connector ring.

Abstract
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.

10. A method of assembling an implantable electric lead comprising a lead body having a lumen, a distal lead portion comprising an electrode, and a conductor electrically connected to said electrode and running in said lumen, said method comprising:
-
mechanically and coaxially connecting a connector coupling and a connector pin designed to be connectable to an implantable medical device to restrain any axial movement between said connector coupling and said connector pin but allow a rotation of said connector pin relative said connector coupling; providing a rotational lock in the form of a circumferential or circumferentially distributed element of an elastically deformable, flexible material in said connector coupling; and mechanically and coaxially connecting said connector coupling and a connector ring electrically connected to said conductor to restrain any axial movement between said connector coupling and said connector ring, and arranging said rotational lock in an interface between said connector coupling and said connector ring to restrain rotation of said connector coupling relative said connector ring.
