User's Manual

BEFORE OPENING THE PACKAGE
Before opening the package, check the "Use by" date printed on the labels on the box and
on the sterile package. Defibrillators that have not been implanted by the end of the “Use by”
date should be returned to Sorin.
Interrogate the device:
― if a warning is displayed, do not implant the device and contact your Sorin representative.
― if battery voltage is below 3V, and if the last reforming/charge occurred more than one
week ago, do not implant the device. Otherwise, wait for one more week before checking
the voltage.
NOTE : The battery voltage can decrease before the expiration date is reached. However,
the battery voltage should be equal to or higher than 3V at the time of implant.
When using the inductive wand, devices MUST NOT be interrogated and/or programmed
within the vicinity of other devices.
Also check the integrity of the sterile package. The sterility of the contents is no longer
guaranteed if the package has been pierced or altered. If the defibrillator is no longer sterile, it
should be returned in its packaging to Sorin. Any re-sterilization of the unit is at the discretion
of Sorin.
PRIOR TO IMPLANTATION
Use the programmer to verify the defibrillator can be interrogated before implantation.
Verify all shock therapies are disabled in order to avoid accidental discharge during
implantation.
It is not advisable to program the Smoothing function before implantation, since the
defibrillator may detect noise and pace at a rate higher than the programmed basic rate.
CAUTION:
Do not shake or tap sharply on the ICD package with the ICD inside, because the ICD's
sensing circuits can interpret this as P-waves or R-waves and record these as an arrhythmia
episode.
High voltage capacitors charge performed on ICD without connected leads using wireless
telemetry can generate false P-waves or R-waves detection.
It is recommended to reset the memory data and statistics before implanting the ICD.
DEVICE PLACEMENT
The pocket should be prepared in the left pectoral position, either subcutaneously or
submuscularly. Subcutaneous device implantation is recommended for optimal RF
communication efficacy.
Implantation in an abdominal position is not advisable.
In its final position, the defibrillator should be no more than 4 cm (1.6 in) below the skin
surface.
CHOOSING THE TYPE OF LEAD
The defibrillator should be connected to:
― one bipolar atrial sensing/pacing lead with or without dedicated SonR sensor
