Abstract
Connector assemblies that are separate from medical lead extensions provide features such as bores for receiving both a medical lead and a medical lead extension and provide electrical connections between connectors of the leads and connectors of the lead extensions. Connector assemblies may include additional features such as contours and wings that reduce subcutaneous erosion. Connector assemblies may also include retention structures such as movable clips that are moved into engagement with leads and lead extensions to retain them within the connector assembly. Integrated lead extension connectors may also include contours and wings as well as retention structures including movable clips.

A connector assembly for receiving an implantable medical lead and a lead extension comprising:
- a body housing a first bore with an external opening and a second bore with an external opening, the body including a plurality of insulative spacers having apertures that are aligned adjacently to define the first bore and the second bore;
- a first plurality of electrical connectors further defining the first bore, each electrical connector of the first plurality of electrical connectors being separated from an adjacent electrical connector of the first plurality electrical connectors by an insulative spacer of the plurality of insulative spacers;
- a second plurality of electrical connectors further defining the second bore, the electrical connectors of the first plurality being paired and electrically coupled to corresponding electrical connectors of the second bore.
A connector assembly for receiving an implantable medical lead and a lead extension comprising:
- a body housing a first bore with an external opening and a second bore with an external opening, the second bore being adjacent to the first bore, the first bore and the second bore defining substantially parallel longitudinal axes;
- and
- an electrically conductive body within the body and extending laterally relative to the longitudinal axes, the electrically conductive body defining a first electrical connector aligned in the first bore and a second electrical connector aligned in the second bore.
A connector assembly for receiving an implantable medical lead and a lead extension, comprising:
- a body housing a first opening and a second opening and defining a first bore;
- a first electrical connector present at the first bore within the body and aligned with the first opening and completely encircling the circumference of the first bore;
- a second electrical connector disposed within the body and aligned with the second opening;
- and
- an electrically conductive path within the body that electrically couples the first electrical connector to the second electrical connector.
An implantable lead extension for receiving an implantable medical lead, comprising:
- an elongated insulative body having a proximal end and a distal end;
- a plurality of electrical connectors on the proximal end;
- a plurality of filars present within the elongated body and being electrically connected to corresponding electrical connectors;
- an extension connector assembly permanently attached to the distal end of the elongated body, the extension connector assembly comprising:
- a body housing a first bore and a groove perpendicular to the first bore, the groove housing a movable clip, the movable clip having a springable end such that movement of the clip moves the springable end into and out of alignment with the first bore;
- and
- a plurality of electrical connectors within the first bore, the plurality of filars being electrically connected to corresponding electrical connectors within the first bore.
