14. IMPLANT PROCEDURE
6. Removing the screwdriver: to avoid all risk of loosening screws during removal, hold the
screwdriver by its metal part and not by the handle.
To ensure full insertion, push the screwdriver's hex tip smoothly into the setscrew until it
reaches the bottom of the hex chamber in the screw, which could be felt as a solid metallic
contact. Do not implant the defibrillator if there is no feeling of solid metallic contact. Do not
implant the defibrillator if the wrench does not click when attempting to tighten the setscrew
on the lead pin.
In the case of an external defibrillation shock delivered to the patient, always check the
programming and functioning of the device, in particular its capacity to deliver shocks.
14.11. DEVICE IMPLANTATION
INTENSIA SonR CRT-D 184 should be implanted with the engraved side facing outwards for
optimal communication with the programming head and radiographic identification.
Carefully wind excess lead and place in a separate pocket to the side of the defibrillator.
It is recommended to not place any excess wire between the can and the heart.
Suture the casing connector to the muscle using the hole provided for this purpose, in order
to avoid potential migration of the device into the pectoral muscle.
14.12. TESTS AND PROGRAMMING
During the implant testing procedure, it is recommended that a security margin of at least 10
J be demonstrated between the effective shock energy and maximum programmable
energy.
Enable shock therapies, then program the defibrillator.
Verify that the defibrillation lead impedance for each shock delivered ranges from 30 to 150
ohms. Check the lead connection if the values are outside these boundaries.
Save the programming data on the programmer’s hard disk and on an external storage
device (if desired).

WARNING: Ensure that the screwdriver's tip is fully inserted in the setscrew; otherwise the
screwdriver can damage the setscrew and prevent connection with or disconnection from
the lead.
NOTE: To optimize cardioversion/defibrillation shocks, electrodes must be positioned so that
the electric field between anode(s) and cathode covers the largest myocardial mass. In
normal conditions, the anode and cathode are adequately separated. In case of a short-
circuit, the shock may be aborted to prevent damaging the defibrillator.
