Abstract
Process and kit for passivating in situ a tip of a probe for an active implantable medical device, particularly for a cardiac pacemaker probe. The probe (10) is of the type comprising a hollow insulating sheath (12) made of a supple material having an internal conductor (14) terminated at its distal extremity by an electrode (16), an axial canal (18) along its length, and a support element (22) at its distal extremity in the neighborhood of the electrode, particularly a metallic filament or blade for shaping or reinforcing the distal extremity (20) of the probe. The support element is of a rigidity that is greater than the combination of the sheath and the internal conductor. The process of the invention is characterized by injection of a solidifiable material (48) in a fluid state in the internal volume of the sheath to fill the region of the distal extremity in a manner so as to coat at least a part of the support element and then to change the state of the solidifiable material to a solid, so as to immobilize the coated support element in the sheath. Advantageously, the injection is driven inside an injection tube (26) which is introduced inside the sheath and sealed in an hermetic manner to the sheath. The kit includes the equipment necessary to inject the solidifiable material into the probe in a passivation procedure.
