Abstract
A lead for an implanted medical device, particularly for a cardiac pacemaker, which has at its extremity distal a hollow cylindrical body (10) presenting at its distal side an opening (22) receiving a stimulation electrode (16) which is mounted axially in this opening, the body and electrode being mechanically fixed and set together by gluing the wall of the body to the wall of the electrode. The internal wall of the body is conformed in a manner to provide between the electrode and body, when the electrode is mounted in the body, a peripheral space defining a chamber (30, 34) between the opposing walls (50, 52) of the body and the electrode. This chamber is a glue expansion chamber essentially closed as compared to the exterior except for an injection canal (32) and an escape canal (36). The injection and escape canals are oriented radially and open in the chamber at two distinct extremities of the chamber such that the chamber could be gradually filled by penetration of glue under pressure by the injection canal and the excess glue escapes by the escape canal once the chamber is filled with glue.
