CONNECTOR ASSEMBLIES FOR RECEIVING IMPLANTABLE MEDICAL LEADS

摘要

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.

主权项

1. 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; anda plurality of electrical connectors within the first bore, the plurality of filars being electrically connected to corresponding electrical connectors within the first bore.
