WARNINGS
General
• Labeling knowledge. Read this manual thoroughly before implantation to avoid damage to the pulse
generator and/or lead. Such damage can result in patient injury or death.
• For single patient use only. Do not reuse, reprocess, or resterilize. Reuse, reprocessing, or
resterilization may compromise the structural integrity of the device and/or lead to device failure which, in
turn, may result in patient injury, illness, or death. Reuse, reprocessing, or resterilization may also create
a risk of contamination of the device and/or cause patient infection or cross-infection, including, but not
limited to, the transmission of infectious disease(s) from one patient to another. Contamination of the
device may lead to injury, illness, or death of the patient.
• Backup defibrillation p rotection. Always have external defibrillation equipment available during
implant and electrophysiologic t esting. If not terminated in a timely fashion, an induced ventricular
tachyarrhythmia can result in the patient’s death.
• Resuscitation availability. Ensure that an external defibrillator and medical personnel skilled in CPR are
present during post-implant device testing should the patient require external rescue.
• Separate pulse generator. Do not use this pulse generator with another pulse generator. This
combination could cause pulse generator interaction, resulting in patient injury or a lack of therapy delivery.
Handling
• Avoid shock during han dling. Program the pulse generator Tachy Mode(s) to Off during implant,
explant, or postmortem procedures to avoid inadvertent high voltage shocks.
• Do not kink leads. Do not kink, twist, or braid the lead with other leads as doing so could cause lead
insulation abrasion damage or conductor damage.
