The invention relates to an implantable quadripolar electrode for sequential neurostimulation of the phrenic nerve. A matrix is provided with two branches each consisting of a hook designed to come in contact with the phrenic nerve without totally encircling it and an extension (), or strip, designed to cross the corresponding incision arranged in the pleura and fix the same on the pericardium, each hook having an orifice allowing the phrenic nerve to pass; The hooks are connected with a bridge designed to keep them at a fixed distance from each other on the longitudinal plane of said phrenic nerve and to allow the rotation of the branches in relation to one another to position the hooks around the phrenic nerve via their respective openings.

A percutaneous gastrostomy catheter includes an internal retainer configured to be maintained pressed against the stomach wall and to disengage itself from a tubing by biodegradation; and an external flange, traversed by the tubing, configured to be pressed against an external face of the abdominal wall and exert, in cooperation with the internal retainer, a pressure adapted to press an external face of the stomach wall against an internal face of the abdominal wall. The internal retainer includes an internal flange. A first face of the internal flange is configured to be pressed against an internal face of the stomach wall, the internal flange being detachable from the tubing under the effect of a simple pulling force. The internal retainer also includes an end piece pressed against the second face of the internal flange, such that the internal flange is between the end piece and the external flange, the end piece being made of a completely biodegradable copolymer or polymer having a bond with the tubing.
