Clip lock mechanism for retaining lead
First Claim
1. An implantable medical device comprising components housed within an enclosure, wherein the components are configured to carry out a desired function, the medical device further comprising:
- at least one lead, the at least one lead terminating in a lead connector;
at least one receptacle within the enclosure for receiving at least one lead connector comprising at least one lead pin; and
a clip pivotally mounted to the enclosure;
wherein the at least one lead pin of the at least one lead connector is inserted into the at least one receptacle; and
wherein the clip pivots over the at least one lead connector to secure the at least one lead to the enclosure.

Abstract
A straight-forward and tool-less mechanism is provided for securing lead wires to an implantable neurostimulator, or similar medical device. In one embodiment, a clip lock mechanism is pivotally connected to the enclosure of the medical device, which enclosure also includes at least one receptacle with contacts to the components within the device. The proximal end of the lead wires terminate in a connector, including at least one plug and at least one pin with contacts corresponding to the electrodes or other devices along the distal end of the lead. The pin is inserted into the receptacle, thus completing the connection between the pin and receptacle contacts, and the clip is pivoted over the plug. The plug preferably has depressions that provide a clear visual and tactual indication of the position of the properly placed clip.
