Abstract: An implantable assembly including an implantable medical lead having, at a first end, a lead connector intended to be received in a connection housing of a connector head for an implantable medical device in order to form a connection to the latter, the connector head having an inlet port defining an interior passage in communication with the connection housing for the insertion of the lead connector into the connection housing, the assembly also including a stiffening member, for stiffening the implantable medical lead, mounted on the first end upstream of the lead connector in order to stiffen the part of this implantable medical lead positioned in line with this stiffening member, the stiffening member being configured to be partially inserted into the interior passage, closing at least the inlet of the latter so as to prevent the passage of body fluid, in particular blood, into the connection housing.

Abstract: The object of the invention is an implantable intervertebral connection device comprising at least two pedicular screws (1, 2) provided in their upper portion with a hexagonal head (3) prolonged by a cylindrical bearing (4, 4′) and an inter-screw connection of adjustable length anchored at each end on said bearings, characterized in that said inter-screw connections constituted, on the one hand, by a ball (7, 7′) preferably of a resiliently deformable material threaded on each bearing (4) and, on the other hand, by two connection elements (E1, E2; E′1, E′2) in prolongation of each other and interconnected by a screw system (17, 18; 18′, 41, 42) for adjustment of spacing, the free ends of the elements being shaped as a cup (8, 9; 8′, 9′) which is concave and threadable on said bearing (4, 4′) and matching said ball (7, 7′) such that in line with each pedicular screw (1, 2; 1′, 2′) the ball will be sandwiched between two cups (8, 9; 8′, 9&p
