Positionable locating and orienting wing for a pacing lead

Claim 1

In a pacing lead assembly comprising a flexible pacing lead including at least one insulated conductor having a proximal end and a distal end, means at the proximal end for electrically connecting the insulated conductor to a pulse generator, a flexible bent or curved configuration in an outer end portion of the lead adjacent the distal end of the lead and an electrode assembly including at least one electrode mounted at the distal end of the pacing lead, the at least one electrode being connected to the conductor, the improvement comprising a positionable, locating, orienting and stabilizing device mounted on the pacing lead and having a passageway through which the pacing lead is received such that said device can be rotated on the pacing lead and cooperating locking means fixed on the lead and adapted to mate and lock with said device in a predetermined position of said device, whereby said device when locked in place in said predetermined position on the lead, has a predetermined orientation relative to the bent or curved configuration in the outer end portion of the pacing lead and whereby said device in its unlocked position can be rotated to a non-obtrusive position relative to the outer end portion of the pacing lead, said device being generally flat and planar in shape and said unobtrusive position being a position where the plane of said flat planar device is generally coplanar with the plane of the bent or curved configuration in the outer end portion of the pacing lead, whereby the pacing lead assembly can be packaged in a flat or flush position on a substrate.
