Quick connector to medical electrical lead

摘要

The quick connector includes an elastomeric sleeve, a rod slidable in the sleeve, and a tube mounted in permanent assembly with one end of the rod. The tube is split at an outer end providing a pair of jaw-like tube segments which extend in divergent relation when in an open position. Each of the segments has a series of longitudinally spaced rearwardly extending barbs. A guide wire having an axially inner end is co-axially embedded in the rod and an axially outer end of the guide wire projects axially outwardly between the diverging jaw-like tube segments. A medical electrical lead is co-axially mounted over the guide wire and between the diverging jaw-like tube segments in radially disposed relation to the barbs. The lead includes a tubular insulation sheath and a coiled conductor in the sheath. The rod and the elastomeric sleeve are axially movable relative to one another after the diverging jaw-like tube segments are moved radially inwardly into a closed position to cause the barbs carried on the thus moved segments to become embedded in the coiled conductor for locking the lead in fixed assembly with the rod.
