•
In models with a IS4-LLLL LV lead port, insert and secure the terminal pin of a IS4-LLLL lead.
WARNING:
When implanting a system which uses both a DF4-LLHH/LLHO and IS4-LLLL lead, ensure that
the leads are inserted and secured in the appropriate ports. Inserting a lead into an incorrect port will result in
unanticipated device behavior (potentially leaving the patient without effective therapy).

De

brillation lead.
•
In models with DF-1 lead ports,
fi
rst insert and secure the de
fi
brillation lead anode (+, proximal) into
the (+) DF-1 lead port. Then insert and secure the lead cathode (–, distal) into the (–) DF-1 lead port.
CAUTION:
For IS-1/DF-1 leads, never change the shock waveform polarity by physically switching the lead
anodes and cathodes in the pulse generator header—use the programmable Polarity feature. Device damage
or nonconversion of the arrhythmia post-operatively may result if the polarity is switched physically.
Connect each lead to the pulse generator by following these steps (for additional information about the torque
wrench, refer to "Bidirectional Torque Wrench" on page 65):
a.
Check for the presence of any blood or other body
fl
uids in the lead ports on the pulse generator header.
If
fl
uid inadvertently enters the ports, clean them thoroughly with sterile water.
b.
If applicable, remove and discard the tip protection before using the torque wrench.
c.
Gently insert the torque wrench blade into the setscrew by passing it through the preslit, center
depression of the seal plug at a 90° angle (Figure 7 on page 57). This will open up the seal plug, relieving
any potential pressure build-up from the lead port by providing a pathway to release trapped
fl
uid or air.
NOTE:
Failure to properly insert the torque wrench in the preslit depression of the seal plug may result
in damage to the plug and its sealing properties.
