Abstract

A screwless quick connection system for connecting a lead connector to a generator of an active implantable medical device is shown and described. The connector head includes a housing receiving a plug of a lead connector. A mechanism for locking the plug into the housing is provided by a U-folded leaf spring. Each branch of the U is provided with a respective hole sized so that the plug passes through the holes on both branches when it is inserted into the housing. The blade is deformable between a free state, in the absence of plug, and a deformed state, with the plug inserted therein. In the free state, both holes are misaligned, while in the deformed state they are aligned. In this way, an edge of both holes exerts by reaction a radial stress force against the smooth outer surface of the plug inserted therein.

First claim

The invention claimed is:

1. A connector head for coupling a lead to a generator body, the connector head comprising:
at least one housing for receiving a plug end of a lead along an axis of insertion;
an elastic element configured to receive and immobilize the plug in the housing, wherein the elastic element comprises a U-shaped leaf spring having a first branch and a second branch, the first and second branches having respective first and second holes that allow the plug to be…
