Abstract

A connector head (10) and a process of joining a connector head to the case (12) of an active implantable medical device, such as a pacemaker, defibrillator, cardiovertor and/or a multisite device. The process includes the steps of a) mechanically and electrically assembling the connector head onto the case; b) injecting of a quantity of a photo-hardening adhesive, in particular a photo-reticulable silicone resin, into an interface formed between the assembled case and the connector head; c) irradiating the quantity of adhesive by a light having a wavelength that is adapted to harden the adhesive; d) optionally affixing a mask on a portion of the case; e) immersing the case provided with its connector head into a photo-hardening resin, so as to form on the case and the connector head a layer of photo-hardening resin coating; and f) irradiating this layer of resin by a light having a wavelength adapted to harden the resin. The connector head (10) is made out of a transparent or translucent material, and it comprises a peripheral lip (18) having a whose surface (20, 22) that mates to the case so as to define a closed volume (24) in an interface between the case and the connector head. The head has an injection opening at one extremity of the closed volume to inject adhesive (14) into the interface and at least one vent opening (16) communicating with the closed volume (24) at another extremity to allow the adhesive to fill the closed volume prior to curing.
